APPEALING WATCH SET

Description

Scope of the invention

[0001] The invention relates to a sympathetic clock assembly, which includes a clock and at least one watch arranged to be placed in a receptacle which includes the clock, in a unique transfer position, said sympathetic assembly including a linking mechanism between said clock and each watch when said watch is placed in said receptacle in said transfer position.

[0002] The invention relates to the very particular field of sympathetic clocks and watches, where these clockwork pieces paired in pairs each include a time base for counting time, and display means for displaying clockwork quantities; in particular these display means are arranged to allow the user to simultaneously view the display on the clock and the display on the watch. Background of the invention

[0003] Since 1800, Abraham-Louis Breguet has designed sympathetic clocks that allow the watches dedicated to them to be wound, set, and adjusted, with no other constraint than placing the watch on the clock.

[0004] These three functions (which is the maximum number of known functions) operate simultaneously at a time defined by the clock's construction, generally once or twice a day. This is the case, for example, with the Breguet clock No. 128 and its associated watch No. 5009, described in George Daniels' book "The Art of Breguet." The timing of the time setting determines the accuracy of the time setting; this explains why this function only occurs once or twice a day for clocks from the 1800s, and every two hours for clocks from the 1990s. It should be noted that watches do not have an hour correction in addition to the minute, as mentioned in George Daniels' analysis, which requires the user to make a preliminary adjustment with an initial rough time setting, on the order of plus or minus fifteen minutes, with the clock making the fine time setting at the same time.

[0005] To date, these types of functions have only been applied to the few existing sympathetic clocks.

[0006] Some self-winding clocks continuously wind the watch's mainspring, using an automatic winding mechanism, and set the minute once or twice a day at fixed times. In this type of clock, the winding of the mainspring must be rapid to ensure the watch is wound within a reasonable timeframe.

[0007] Some sympathetic clocks ensure the adjustment of the rate which is derived from the setting of the watch.

[0008] Several disadvantages arise from the construction of these friendly clocks: If the watch is continuously placed on the clock, it will be set periodically (every two hours, twelve hours, or twenty-four hours), which unnecessarily stresses the time-setting mechanism; if the watch is continuously placed on the clock, and if the winding is constant and rapid, the automatic barrel required in this case suffers significant wear; if the watch is stopped when the user places it on the clock, the time will not be set, and it is necessary to wait for the next time to be set, for an uncertain time setting; if the watch is stopped when the user places it on the clock, and the winding is scheduled to be periodic with the time setting, the winding will not take place before the next time to be set, and therefore the watch will not work and the prior time setting to plus or minus fifteen minutes will be lost;If the watch is stopped when the user places it on the clock, and winding is intended to be constant at a slow speed, it will not reach full winding for several days; if the watch is stopped when the user places it on the clock, and winding is intended to be constant at a fast speed, it will not reach full winding more quickly, but if the watch remains stored on the clock, this fast speed will stress the sliding bridle function of the mainspring barrel and cause premature wear; only the minute-setting and winding functions are guaranteed, other functions are difficult to ensure or add. Summary of the invention

[0009] The invention aims to improve the functionality of sympathetic clocks and watches, by overcoming the drawbacks of the known technique.

[0010] The invention aims to develop a set consisting of a clock and at least one watch, which: ensures optimal winding of the watch at all times as soon as it is placed on the clock; ensures the time setting at the user's request, for example before taking the watch to wear it; allows for precise time setting, to the second for example; allows for complete time setting, even if the watch has stopped; allows for the transmission of more information than just the minute, for example: second, minute, hour, date, phase and / or age of the moon, day of the week, week, month, year, leap year, or other.

[0011] The clock is a true autonomous timepiece, with its own time base, and its own display of time and quantities related to the complications it includes.

[0012] For this purpose, the invention relates to a sympathetic assembly according to claim 1. Brief description of the drawings

This probe has a rake that cooperates with a gear arranged to drive a second actuator; more specifically, this gear is an input gear of a differential mechanism, one output of which is the leftmost transfer shaft in the figure, and which is arranged to drive a second actuator via a linkage; the figure 12 illustrious, in a similar way to the Figure 10A similar but less bulky design uses two snail cams, one with fewer than 12 steps for reading the hours, and the other with more than 30 steps for reading the two-minute increments; similarly, each is traversed by a feeler, whose rake constitutes an input for the differential that corrects the unit difference; figures 13 to 18 illustrate a seventh variant of setting the reference time on displays: the figure 13This schematic diagram, in plan view, represents part of the mechanism of the sympathetic watch, which includes a hammer, similar to a chronograph hammer, in a cocked position where it is held by a ratchet and tensioned by a spring, and an active position where it bears against the periphery of a first heart-shaped hour cam, thus constraining it to rotate to its smallest radius. This first heart-shaped hour cam is similar to those used in chronograph mechanisms and is carried by the hour wheel. A second truncated heart-shaped minute cam is carried by the minute display.

Figures 16 and 15 ; THE figures 19 to 21 illustrate an eighth variant of setting the reference time on displays: the figure 19represents, schematically and in plan view, part of the mechanism of the sympathetic watch, which includes a ratchet with a ratchet spring, a rack meshing with an hour wheel and disengaging clockwise from the hour wheel, driven by a return spring, a rack pinion (or hour pinion), a first hour cam carried by the hour wheel and having an opening, and a second minute cam carried by a minute display mechanism and having a wolf's tooth opening or notch, and a jumper arranged to cooperate with a star attached to the minute display mechanism;

the figure 26 is a flowchart showing a 12-hour cycle between the clock and the watch, with an optional request for DMAH time setting by the user, and R winding and MAH time setting actions; the figure 27 , similar to the figure 1, represents the clock with its still empty receptacle, at 10:09, and the watch displaying 08:17; the clock here has three actuators, a first actuator approximately at four o'clock on the watch, a second actuator approximately at eight o'clock on the watch, and a third actuator arranged to cooperate with the watch's crown at three o'clock, all arranged in a star shape around the receptacle, here constituted by a shaft with a pivoting movable part; the figure 28 , similar to the figure 27 , represents the watch inserted into its receptacle; the figures 29 to 33 illustrate the main steps of setting the time and winding, and each includes the simultaneous display of the watch on the left and the clock on the right: the figure 29 represents the watch ready to be wound and set, as it appears on the figure 28 ; there figure 30represents the winding of the watch by the rotation of a winding sleeve, constituting the third actuator, driving the watch crown, which is wound by the equivalent of thirteen hours of autonomy, either on demand by the DMAH user, or periodically, every twelve hours at a fixed time; the figure 31 represents the stopping of the watch by the action of a stop lever on the resonator's balance wheel; the clock, via the first actuator at four o'clock, controls this stopping of the watch's resonator, the disengagement of the gear train's hands, and the return of the hands to a reference position, here chosen at 12:00; the figure 32represents the movement of the watch hands in increments of a predetermined step, chosen to be three minutes in this example, until they reach the position of the instantaneous time displayed by the clock, here 10:12, plus a three-minute step, therefore at the position 10:15; it is the clock that transmits this instantaneous time value to the watch, after reading it from the clock's snail-shaped mechanism(s), by means of the required number of pulses to control the overall movement of the hands; the watch is then ready to restart, and is only waiting for the release of its stop lever, which will be controlled by the clock; the figure 33 represents the start of the watch by releasing the stop lever; when the clock passes through the 10:15 position, the watch is then set to the time with the best possible accuracy and is ready to be worn by the user; the figure 34 is a perspective view of the whole sympathetic Figures 27 and 28, with the clock according to the execution of the figure 12 ;

figures 37 to 45 are logic diagrams comprising the elementary operations of the processes according to nine variants described later, respectively from the first variant to the ninth variant. Detailed description of preferred embodiments

[0014] The invention relates to a sympathetic clock assembly 1000, which includes a sympathetic clock 100, which includes a clock hour display 104, and a clock minute display 105, and at least one sympathetic watch 200, which includes a watch hour display 4, and a watch minute display 5, and which is arranged to be placed in a receptacle 150 which includes the clock, in particular at the level of a stretcher 670, in a unique transfer position, this sympathetic assembly 1000 includes at least one linking mechanism between this clock 100 and each watch 200 when this watch 200 is placed in the receptacle 150 in the transfer position.

[0015] According to the invention, this at least one linking mechanism comprises at least two separate transmission lines, one for selecting a function to be performed or a display value to be adjusted, and the other for transferring energy or movement, and / or transmitting a pulse.

[0016] More specifically, at least one transmission line, and more specifically each transmission line, includes a shaft. More specifically, this shaft is at least rotatable.

[0017] More specifically and without limitation, at least one of these trees, or each of these trees, is similar to that of the Breguet clock No. 128 (G. Daniels: Art de Breguet: page 277).

[0018] At least one such shaft, and more specifically each shaft, is divided into two half-shafts between the clock 100 and the watch 200 in question. These two half-shafts are arranged to cooperate in driving each other when the watch 200 is placed on the clock 100 in the receptacle 150 in the transfer position, either by direct drive, and more specifically by coaxial drive, or via a gear train or a wheel. The transmission between these half-shafts is not described in detail here; any suitable drive mechanism can be used, such as teeth, splines, dog clutches, friction drives, or the like. The half-shafts can cooperate end-to-end, internally to each other, tangentially to each other, or via a gear train or wheel, or the like.

[0019] These at least two transmission lines share the different functions.

[0020] The invention is more particularly described with two transmission lines, in the form of at least two shafts: a first selection shaft 1 and at least a second drive shaft 2. Naturally, some of the functions described below can be broken down and handled by other additional shafts.

[0021] The first selection shaft 1 transmits a function selection, one of the functions being a neutral / winding function for recharging the energy of a 200-watch. This transmission is specifically of the alternating function type: neutral-winding, date, hours, minutes, or others, distributed over 360°. The first selection shaft 1 is comparable to a selector, a machine controller, or a column wheel of a chronograph or complicated watch.

[0022] The second drive shaft 2 transmits force, particularly torque, for recharging energy, specifically for winding a mainspring barrel or a watch 200 from the clock 100, and / or for transmitting an adjustment or setting value to a watch 200, in the form of a rotation angle based on a value given by the clock 100, and / or for imparting an impulse to a component of the watch. The adjustment or setting value may correspond to one of the quantities displayed by the watch; it may also be an adjustment value of the watch's resonator, achieved by acting on a regulator, a balance spring stud, a flexible blade, an inertia adjustment, or other means.

[0023] The first tree 1 and the second tree 2 are distinct from each other; in one variant, they can extend along parallel axes, or even coincide.

[0024] In one particular variant, their axes are coplanar.

[0025] In another particular variant, their axes intersect.

[0026] The invention allows the adjustment, in particular the setting of the time, of a watch 200 by at least two separate shafts 1 and 2, the first of which indicates the type of correction desired, and the others the correction values, at least one of the latter being devoted to the function of recharging the energy of the watch, in particular a rewinding of the barrel.

[0027] The first shaft 1 and / or the second shaft 2 can be mobile in different ways, in translation and / or in rotation.

[0028] In one variant, the first tree 1 and the second tree 2 are mobile in rotation.

[0029] In one variant, the first tree 1 and the second tree 2 are mobile in translation.

[0030] In one variant, one of the first tree 1 and the second tree 2 is mobile in rotation, and the other is mobile in translation.

[0031] In one variant, one of the first tree 1 and the second tree 2 is mobile in rotation and translation, and the other is mobile in translation.

[0032] In one variant, one of the first tree 1 and the second tree 2 is mobile in rotation and translation, and the other is mobile in rotation.

[0033] In one variant, the first tree 1 and the second tree 2 are mobile in rotation and translation.

[0034] Advantageously, the setting is sequential, and starts with a neutral position in which energy is recharged; this neutral position is followed, preferably after a certain predefined duration, or by action of the user, by at least one elementary sequence of adjustment of one of the quantities displayed by the watch, or by the triggering of a particular function.

[0035] More specifically, the watch adjustment settings are made sequentially, with each measurement being adjusted independently of the others.

[0036] More specifically, this sequential time setting is performed by a dedicated mechanism, in parallel with the traditional time-setting mechanism of the watch.

[0037] More specifically, the sequential time setting is controlled by the clock. In particular, in one specific variant, the interval between two elementary sequences is adjustable. More specifically, each interval between two elementary sequences is adjustable.

[0038] Advantageously, the timing system defining the tempo of the elementary sequences, controlled by the clock, defines the triggering moment (or the signal) for the start of the watch, which is previously held in a stopped position by a stop mechanism 20 comprising, in particular but not limited to, a stop-seconds mechanism 25 with a stop lever or similar. The embodiments described below include, in particular but not limited to, a stop lever arranged to cooperate with an inertial mass 15, in particular a balance wheel, or a resonator 10, for its locking or release.

[0039] More specifically, the adjustment setting or sequential time setting corrects, without limitation, all or part of the following indications: hour, minute, date, day, month, and / or any other indications.

[0040] The neutral position allows the watch to be recharged or wound, and this winding is controlled by the watch.

[0041] This first tree 1 and this second tree 2 allow the collaboration between the clock 100 and a watch 200 in the manner shown below.

[0042] The first tree 1 includes a first lower half-tree 11 of the clock 100 and a first upper half-tree 12 of the watch 200.

[0043] When watch 200 is absent, i.e. not placed on clock 100, and when clock 100 does not carry any watch 200, these two half-trees intended to together constitute the first tree 1, namely the first lower half-tree 11 and the first upper half-tree 12, are each in neutral position.

[0044] Similarly, the second tree 2 has a second lower half-tree 21 of the clock 100 and a second upper half-tree 22 of the watch 200.

[0045] When the watch 200 is placed on the clock 100, the first lower half-shaft 11 and the first upper half-shaft 12, on the one hand, and the second lower half-shaft 21 and the second upper half-shaft 22, on the other hand, are aligned. Since the first lower half-shaft 11 and the first upper half-shaft 12 are in the neutral position, the selected function is neutral / winding. Setting the watch is facilitated by the independent indexing of each half-shaft to its neutral position, which are naturally indexed.

[0046] The clock 100 is arranged to deliver a torque on the first shaft 1 in the presence of the watch 200. The rotation of this first shaft 1 is regulated by a regulating mechanism, for example of the minute repeater regulator type.

[0047] Each 200 watch is designed to release or block the rotation of the second shaft 2 depending on the level of energy it has stored, specifically depending on the winding of the mainspring barrel in a given case, according to a defined hysteresis, for example, by a power reserve mechanism. This rotation of the second shaft 2 is, in this particular case, transmitted to the winding of the mainspring barrel and ensures its winding. In this neutral position, the 200 watch therefore ensures its winding at all times within a defined range.

[0048] The clock 100 includes at least one control means 300, which is arranged to be operated by the user, or to be controlled by the clock's time base, to rotate the first lower half-shaft 11, to select the function of the first shaft 1.

[0049] When the watch 200 is placed on the clock 100 and the user requests the time to be set, using a control device 300, such as a lever (particularly one present on the clock 100), the adjustment or time setting of the watch 200 is performed by a sequence of functions controlled by the clock 100. For example, this might involve adjusting the date, hour, minute, and second values ​​to the current time. Following the user's request, the adjustment sequence to the current value begins, for example, for a time-setting sequence. Each sequence starts at a precise tempo, which is defined by the time base of the clock 100.

[0050] Naturally, it is also possible to install a control means 300 on the watch 200, instead of installing it on the clock 100, or to equip both the clock 100 and the watch 200, each with a control means 300. If the control means 300 is only on the watch, this allows the function to be locked, as long as the watch 200 is not in the transfer position in the receptacle 150.

[0051] In the particular case where the sympathetic 1000 assembly is arranged for the successive adjustment of the date, hour, minute and second values, several elementary sequences follow one another.

[0052] During the first elementary sequence, the clock 100 rotates the first shaft 1 to the date position and rotates the second shaft 2 by an angle corresponding to the instantaneous value of the date. The watch 200 recognizes the rotation of the first shaft 1 to the date position, actuates the stop lever, which stops the resonator and the watch, sets the date, hour, minute, and second displays to the zero position, and applies the value transmitted by the second shaft 2 to the date display.

[0053] Here, "display" means any known moving display element in watchmaking: hand, ring, disc, cursor, flag, city or time zone display, moon phase display, leap year display, AM / PM display, day / night display, power reserve indicator, alarm selector, wake-up indicator, calendar display, or other.

[0054] After a predetermined initial duration D1, for example 2 minutes, the clock 100 triggers the second elementary sequence. During this second elementary sequence, the clock 100 rotates the first shaft 1 to the hour position and rotates the second shaft 2 by an angle corresponding to the instantaneous value of the time. The watch 200 recognizes the rotation of the first shaft 1 to the hour position and applies the value transmitted by the second shaft 2 to the time display 4 of the watch 200.

[0055] After a second predetermined duration D2, for example two minutes, the clock 100 triggers the third elementary sequence. During this third elementary sequence, the clock 100 rotates the first shaft 1 to the minute position and rotates the second shaft 2 by an angle corresponding to the instantaneous value of the minutes, plus the value of a third predetermined duration D3, which separates the third elementary sequence from the next change of elementary sequence, which will be the last adjustment before the watch 200 is released from its running function. The watch 200 recognizes the rotation of the first shaft 1 to the minute position and applies the value transmitted by the second shaft 2 to the minute display of the watch 5.

[0056] After the third predetermined duration D3, for example two minutes, the clock 100 returns the first shaft 1 to the neutral / winding position. The watch 200 recognizes the rotation of the first shaft 1 in the neutral / winding position and releases the stop lever; the watch 200 is then fully adjusted and set to the correct time, and starts precisely on the second.

[0057] The playful and practical nature of this design is noteworthy: in this example, in 6 or 8 minutes (if the first sequence starts after a two-minute transition period D0), watch 200, presented on the clock in an unwound, stopped, and unset state, is wound and fully set to the correct time, including the date. A special option is to add a perpetual calendar to clock 100, which then allows the simple date display of watch 200 to be corrected at the user's request via the control unit 300.

[0058] More specifically, the 100 clock is a mechanical movement clock.

[0059] In one variant, the clock 100 receives a signal from a time base, for example a radio-controlled signal, GPS, a signal from an electronic clock, or other, and includes means for transforming the signal indicating the instantaneous time into movements of mechanical components, for the transmission of the information to a watch 200.

[0060] In one variant, all energy and motion transfers between clock 100 and watch 200 are mechanical and / or magnetic.

[0061] In one variant, all energy and motion transfers between the clock 100 and the watch 200 are mechanical.

[0062] In one variant, all energy and motion transfers between pendulum 100 and watch 200 are magnetic.

[0063] In one variant, no energy and / or movement is transferred through the watch's winding and time-setting stem.

[0064] More specifically, each half-shaft 12, 22, which comprises the watch 200 is distinct from the winding and time-setting stem of the watch 200 when it has one.

[0065] In one variant, no energy transfer is made through the watch's winding and time-setting stem.

[0066] In one variant, no transfer of movement is made through the winding and time-setting stem of the watch.

[0067] The winding system does not require a sliding-flange barrel and avoids wear and tear on it. Winding takes only a few minutes and can be done whenever the watch 200 is placed on the clock 100, and as needed.

[0068] Since adjustments, particularly time setting, are made on demand, wear on the mechanisms is limited when the watch 200 is stored on the clock 100 for extended periods. In such cases, time setting can be triggered at regular intervals, for example, once a week, by a command sent from the time base of the clock 100.

[0069] This invention makes it possible to create a user-friendly clock adapted to the needs of today's users, offering both practical and entertaining uses as described above. It represents a true evolution of a product known for two hundred years.

[0070] The 100 clock's movement, more stable and precise than that of the 200 watch, keeps the latter on time when not worn, and corrects it on demand.

[0071] The great autonomy of the 100 clock is brought to the 200 watch: when it is not worn, it allows, for example, weekend wear and weekday maintenance at an ideal operating range.

[0072] Different variants of the sympathetic 1000 watch assembly according to the invention, and different variants of use, are described below.

[0073] Such a sympathetic assembly 1000 comprises a sympathetic clock 100 and at least one sympathetic watch 200, which is arranged to be placed in a receptacle 150 of the clock 100, in a unique transfer position. The sympathetic assembly 1000 includes a linkage mechanism having at least two separate transmission lines between the clock 100 and each watch 200 when the watch 200 is placed in the receptacle 150 in the transfer position.

[0074] The sympathetic clock 100, which is arranged for the energy recharging and display and / or timing adjustment of at least one sympathetic watch 200, includes at least one actuator for carrying out the energy recharging and / or display and / or timing adjustment of at least one sympathetic watch 200 placed in the receptacle 150 in the transfer position.

[0075] And the clock 100 includes at least one first actuator of the clock 501, movable between a rest position and an activated position, to control the activation or deactivation of a mechanism that includes the watch 200. And the clock 100 includes at least one other actuator of the clock 502; 503, which is arranged to impart a series of pulses or to transmit a mechanical torque to a receiver that includes a watch 200.

[0095] More specifically, the clock 100 includes a stop control mechanism 120, which is arranged to transform a step-by-step time-setting command made by a user or by the clock 100, into a sequence, the first step of which is an action to control a stop mechanism 20 and / or to disengage the displays that a sympathetic watch 200 includes.

[0096] More specifically, this stop control mechanism 120 is arranged to control a movement of a transmission line to identify a time-setting action, and to control the transfer of a pulse or torque to a stop mechanism 20 that is included in the watch 200.

[0097] With regard to the sympathetic 200 watches, advantageous, non-limiting types are described below: a heart and hammer version, a ratchet and double cam version, and a ratchet, rake and double cam version.

[0098] These watches share common characteristics.

[0099] In both versions of the watch, the sympathetic watch 200 has at least one energy storage barrel, for powering at least one resonator 10 that this watch 200 has. The watch 200 has a display gear and a finishing gear.

[0100] To set the time, it is necessary to use a clutch mechanism and / or a resonator stop mechanism. For this purpose, for all the time-setting devices and methods presented in this description, the watch 200 comprises either a stop mechanism 20 arranged to stop the operation of the resonator 10, or a clutch mechanism allowing the display to be disengaged from the finishing gear train, or both such a stop mechanism 20 and such a clutch mechanism.

[0101] The clutch, when open, allows the rotation of the displays, including the hands, independently of the finishing gear, whether for moving these displays towards a predetermined reference time, or for moving towards the exact instantaneous time (step-by-step time setting, or relative time setting, or permanent time setting), or for moving an offset (version with top seconds), and, when closed, to drive the displays or hands.

[0102] The use of a stop mechanism 20 incorporating a stop-seconds mechanism 25, particularly with a stop lever, is necessary for certain time-setting modes, such as continuous time setting. It also offers an advantage for step-by-step time-setting modes, where the stop mechanism 20 allows for a precise start at 0 seconds, or for relative time-setting modes where the user can observe the inertial mass 15 of the resonator 10, specifically a balance wheel, at rest during the time-setting process. In these two time-setting modes, the clutch alone can start the hands without the balance wheel being stopped; the display of the seconds hand is then random: ±30 s.

[0106] The 500 reset mechanism is arranged to return at least one, and more specifically but not limited to each, display 3; 4; 5, of the 200 watch to its reference position. For this purpose, the reset mechanism 500 includes, for at least one display 3, 4, 5, at least one core 401, 702, 703, which is rotationally fixed to the display concerned 3, 4, 5, and the reset mechanism 500 includes at least one hammer 402, 701, which is arranged to cooperate in support with a core 401, 702, 703, under the pressure of a spring when it is released by the activation of the reset mechanism 500.

[0108] In particular, the hammer 402 or 701 is unique, and common to all the hearts 401, 702, 703, which comprise the watch 200, for the adjustment of the display for the different corresponding horological quantities.

[0109] More specifically, the watch 200 includes such a stop mechanism 20, and a first watch actuator 901, which is arranged to be actuated by the clock 100, to control this stop mechanism 20 to block or release the movement of its resonator 10 and / or a disengagement mechanism for the displays of the watch 200.

[0110] More specifically, the first actuator of the 901 watch is arranged to ensure the re-cocking of the 402, 701 hammer.

[0111] More particularly, this stopping mechanism 20 includes a stop-seconds mechanism 25 comprising a stop lever arranged to cooperate in support with an inertial mass 15 of the resonator 10 in a blocking position, and to remain at a distance from the inertial mass 15 during the normal operation of the resonator 10.

[0114] More specifically, the 200 watch includes a second actuator of the 902 watch, which is capable of operating in a back-and-forth motion, to drive a minute display 5 of the 200 watch, by steps of a given value, and to indirectly drive, through this minute display 5, an hour display 4 of the 200 watch.

[0115] The 200 watch is designed for step correction of the display, with correction steps of a predetermined value, for example, two minutes. This correction step is an integer submultiple of the hour: one minute, two minutes, three minutes, four minutes, five minutes, six minutes, ten minutes, twelve minutes, fifteen minutes, twenty minutes, thirty minutes. The 200 watch features a minute wheel, which is precisely positioned by means of a 30-tooth, 15-tooth, or other type of star wheel with a number of teeth corresponding to the number of correction steps chosen per hour.

[0116] The watch 200 advantageously comprises at least one first upper half-shaft 11 for selection and at least one second upper half-shaft 12 for drive, and the watch 200 is arranged to recognize the movement of a transmission line for selection or a transmission line for drive in the time-setting end position, where the first upper half-shaft 12 is arranged to actuate the stop lever of the stop mechanism 20, to release the resonator 10, and / or a disengagement mechanism for the displays, and to allow the watch 200 to run.

[0123] The 200 watch advantageously features a time-setting friction suitable for allowing the transfer of torque from the winding mechanism, or features a clutch mechanism instead of a time-setting friction.

[0124] More specifically, the watch 200 includes at least one clutch mechanism, which is arranged for engaging or disengaging a display 3, 4, 5. In particular, this clutch mechanism 706 between the display gear 705, 707, 708 and the finishing gear 710, includes a friction spring 709.

[0125] More specifically, the 200 watch features a 5-minute display, which is designed to rotate clockwise or counterclockwise, and includes a ratchet mechanism. This ratchet is designed to unlock when the 5-minute display is moved to the setting position and to lock the minute display in the reference position. The 200 watch also advantageously incorporates a friction mechanism designed to allow the watch to continue rewinding after this locking action during counterclockwise rotation.

[0126] The watch 200 notably includes a hammer 701, which is movable between a cocked position, where the hammer 701 is held by a ratchet and tensioned by a spring, and an active position, where the hammer 701 is positioned to bear against the periphery of a first heart-shaped hour cam 702, carried by an hour wheel 708, so as to constrain it to rotate to its smallest radius. The watch 200 also includes a star mounted on a minute display mechanism, cooperating with a jumper 704, 7040, to maintain each display position at a regular interval.

[0127] And the 200 watch features a second 703 minute cam in the shape of a truncated heart, carried by a 705 minute display to guarantee the display position to the minute.

[0128] In both watch versions, the convenient 1000 assembly includes a controller mechanism for setting the displays to the reference position. Specifically, this controller mechanism includes at least one 840 column wheel.

[0129] More specifically, the 200 watch includes a function controller, capable of occupying at least two positions, the first corresponding to the start of the function where the controller is arranged to control the disengagement of the finishing gear, and stop the inertial mass 15 of the resonator 10, and the second corresponding to the end of the function where the controller is arranged to release the clutch and the balance wheel.

[0130] In one variant, the function controller is able to occupy, between the first position and the second position, an intermediate position in which the controller commands the cocking of the hammer.

[0131] Alternatively, the function controller is integrated into the 200 watch, and includes either a rotary controller, of the column wheel type, controlled by the interface, with two to five successive stable positions, or a shuttle-type back-and-forth controller, controlled by the interface, with two successive stable positions.

The 200 watch also includes a finishing gear train with a ratchet mechanism, designed to wind at least one mainspring barrel during a counterclockwise rotation.

[0143] More specifically, the interface is arranged to drive, in addition to the rotation of at least one display 3, 4, 5, in a counter-clockwise direction, a manual winding gear of at least one barrel, by means of an external ratchet mechanism to a finishing gear that comprises the watch 200.

[0147] And the 200 watch features a clutch mechanism 806 between a display gear 805, 807, 808, and a finishing gear 810.

[0148] The 1000 assembly includes an interface between the clock 100 and the watch 200. This interface is arranged to disengage the clutch mechanism 806 by actuating it to its disengaged position, allowing the rack 823 to drive the hour and minute display gear of the watch 200 counterclockwise, for as many revolutions as necessary, until the pawl 801 meets the opening 8020 of the first hour cam 802, corresponding to the minutes preceding a reference hour corresponding to a predetermined reference position of the displays 3, 4, 5 of the watch 200. At this point, the pawl 801 can bear against the second minute cam 803 for a rotation corresponding to the last minutes before reaching this reference hour, and until it locks in the toothed opening 8030. of the second cam of minutes 803, the blockage corresponding to the reference display position.

[0149] The time-setting mechanism controlled by the clock 100 is arranged to set the displays 4, 5, of the watch 200, clockwise, to the correct time by resetting the rack 801.

[0150] The interface between the clock 100 and the watch 200 is further arranged to reconnect the finishing gear with the display gear, by engaging the clutch mechanism 806 to reset the rake 801 or complete the resetting of the rake 801.

[0151] The cooperation between the jumper 804 and the star allows the displays to be maintained in each step, and allows the rake 801 to be reset without loss of display.

[0152] The star, carried by the minute display 5, is either a thirty-toothed star cooperating with a single-tooth 804 jumper, or a fifteen-toothed minute wheel pinion cooperating with one tooth at a time of a double 8040 jumper having two teeth, or has a number of teeth that corresponds to the whole number of predetermined steps contained in an hour.

[0153] The clutch mechanism 806 advantageously includes a friction spring 809.

[0154] More specifically, this clutch mechanism 806 is a chronograph clutch mechanism, comprising a clamp 821 whose function is to ensure the engagement and disengagement, under the control of a column wheel 840 which controls the angular separation of the arms of the clamp 821, 822, for the opening or closing of the clamp, corresponding respectively to disengagement or engagement.

[0155] As in the hearts and hammer version, the friendly 1000 set includes a controller mechanism, either inside or outside the 200 watch, for controlling the setting of the displays in the reference position.

[0156] More specifically, this function controller is capable of occupying at least two positions, the first corresponding to the start of the function where the controller is arranged to control the disengagement of the finishing gear, and stop the resonator's balance wheel, and the second corresponding to the end of the function where the controller is arranged to release the clutch and the balance wheel.

[0157] More specifically, the function controller is integrated into the 200 watch, and comprises either a rotary controller, of the 840 column wheel type, controlled by the interface, with two to five successive stable positions, or a shuttle-type back-and-forth controller, controlled by the interface, with two successive stable positions.

[0158] More specifically, the function controller is external to the watch 200 and is housed in the clock 100, and the watch 200 has only one reciprocating cam driven by the interface and returning to rest by default, and has a stable rest position, and one to three driven positions.

[0159] More specifically, the function controller includes a snail cam and a two-position cam.

[0160] In a first specific variant, known as step-by-step time setting, the Sympathique 1000 set is arranged to allow for step-by-step time setting. More specifically, this Sympathique 1000 set, comprising a Sympathique 100 clock and at least one associated Sympathique 200 watch, is designed to perform the following functions: The watch starts running when it is placed on the clock; the watch is wound with the assurance of a minimum twelve-hour power reserve when it is removed from the clock; the watch keeps running when it is on the clock; the watch sets the time when it is placed on the clock or on demand, to within 15 seconds; the watch keeps the time as long as it is on the clock; the possibility of deactivating the function for possible storage of the stopped watch on the clock.

[0161] In this first variant, the step-by-step time setting can be done at the user's request at the control means 300, and / or automatically, i.e. controlled by the clock 100, in particular by a mechanism linked to the rotation of the displays of the clock 100, in particular and not limited to an hour display of the clock 104, and a minute display of the clock 105. The command performed by the clock 100 can be periodic, or linked to an auxiliary mechanism set by the user, called an alarm type, analogous to an alarm clock mechanism; this command performed by the clock 100 is executed only if a watch 200 is present in the receptacle 150, in the transfer position.

[0162] Setting the time is only of interest to the user, except for demonstration purposes, if the 200 watch is not completely unwound. Therefore, setting the time generally follows a rewinding, or more generally, a recharging of the 200 watch's energy. This description is simplified by using the terms "winding" or "rewinding" for any recharging or charging of energy, respectively.

[0163] The 200 watch classically includes displays, 3, 4, 5, and in particular and not limited to an hour display for watch 4, and a minute display for watch 5. The figures illustrate non-limiting variants where these displays are hands.

[0164] More specifically, the command issued by the clock 100, or the user's action on the control means 300, has the initial effect of positioning one of the transmission lines to a position corresponding to the time setting. One of the transmission lines is then capable of imparting to a time-setting mechanism, which is internal to the watch 200, the movement(s) necessary to accurately display the current time.

[0165] The invention is described below in a non-limiting embodiment, in which one of the transmission lines between the clock and the watch comprises a first clock actuator 501, which is arranged to cooperate with a first watch actuator 901 for starting or stopping the watch, and another of these transmission lines comprises a second clock actuator 502, which is arranged to cooperate with a second watch actuator 902, in particular a pusher or similar, which incrementally provides the setting motion. In another embodiment, these pushers may be combined. In yet another embodiment, another transmission line comprises a third clock actuator 503, arranged to cooperate with one of the watch actuators.

[0166] The watch 200 includes a resonator 10, which includes at least one inertial mass 15; the present description concerns the most common case of a balance-spring type resonator, where the inertial mass 15 is a balance wheel.

[0167] The watch 200 is equipped with a stop mechanism 20, arranged to stop the operation of the resonator 10, notably by the pressure of an arm, or a leaf spring, or another actuator, on the inertial mass 15 or on a suitable element of the resonator. More specifically, this stop mechanism 20 is a stop-seconds mechanism 25 comprising a stop lever.

[0168] The clock 100 includes a stop control mechanism 120, which is arranged to transform the step-by-step time-setting command performed by the user or by the clock 100, into a sequence, the first step of which is a control action of the stop mechanism 20 of the watch 200.

[0169] The stop control mechanism 120 of the clock 100 is arranged to control a movement of one of the transmission lines to identify the time-setting action, and to control the transfer of a pulse or torque to the stop mechanism 20 of the watch 200.

[0170] The time-setting sequence is as follows: To perform the time setting, the resonator 10 is stopped, in particular the balance wheel 15 of the watch 200, is stopped and the displays of the watch 200 return to the reference position, in particular 12:00, instantaneously; the hour 4 and minute 5 displays of the watch 200 then reach, by successive steps, a restart display position which corresponds to the exact instantaneous time, plus the value of at least one additional step imposed by the mechanism, in particular a step of two minutes; at the passage of the next two minutes, that is to say at the instant corresponding to the restart display position which has just been reached, the resonator 10, in particular the balance wheel 15, of the watch, is released by the stop mechanism 20 of the watch 200, in particular by this stop-seconds mechanism 25.

[0171] To do this, the watch 200 recognizes the movement of the transmission line between the clock 100 and the watch 200 in the time-set position, a first actuator of the watch 901 (in particular a pusher or similar) actuates the stop lever of the stop-seconds mechanism 25, which stops the resonator 10 and the watch 200. This first actuator of the watch 901 is advantageously also a control mechanism of at least one hammer or similar, and causes the positioning of the hour 4 and minute 5 displays of the watch 200 in the reference position, by bringing into cooperation, for each adjusted horological quantity, a hammer with a heart carried by a carriage.

[0172] Thus, more specifically, the step-by-step time setting involves a sequence of steps, described here with numerical values ​​for the step that are by no means limiting:

[0173] When the time-setting command is given by the user at the control means 300, or given by the clock 100 itself, the control means 300, or a clock movement 900 which includes the clock 100, activates the stop control mechanism 120, which immediately commands the stop mechanism 20 of the watch 200, through the first pusher 901.

[0174] The resonator 10 is then stopped, in the particular case illustrated here the inertial mass 15 is stopped.

[0175] The watch 200 has at least one display 3, 4, 5; more specifically, and without limitation, this description relates to the setting of an hour display on the watch 4, and a minute display on the watch 5

[0176] The watch 200 includes a reset mechanism 500, which is arranged to return at least one display 3, 4, 5 of the watch, in particular the hour display of the watch 4 and the minute display of the watch 5, to a reference position, in particular for example the reference position, in particular 12:00, i.e. twelve hours and zero minutes, or, as seen on the figures 27 to 33 The 10:10 position, that is, ten hours and ten minutes, or any other value. Unless otherwise indicated in this description, the reference position is this reference position of 12:00, twelve hours and zero minutes.

[0177] More specifically, this 500 reset mechanism is arranged to return each display 3, 4, 5 of the watch to its reference position.

[0178] In a non-limiting embodiment, this reset mechanism 500 comprises, for each display 3, 4, 5, a core 401, 702, 703, which is rotationally fixed to this display 3, 4, 5, and the reset mechanism 500 comprises at least one hammer 402, 701, which is arranged to cooperate in support with this core 401, 702, 703, during the activation of the reset mechanism 500; preferably this hammer 402, 701, is returned by a hammer spring 403 which tends to move it away from the core 401, 702, 703, in normal operation.

[0179] In a particular variant, the hammer 402, 701 is unique, and common to all the hearts 401, 702, 703, which comprise the watch 200 for the different horological quantities to be adjusted.

[0180] The stop mechanism 20 thus commands, simultaneously with the stopping of the watch 200, the resetting of its display by activating its reset mechanism 500 to return each display 3, 4, 5, to its reference position.

[0181] Thus each display 3, 4, 5, of the 200 watch instantly takes the reference display position, for example the twelve o'clock and zero minute position.

[0182] Another transmission line is then driven by the clock to impose a particular display on the watch; instead of being continuous, this drive is performed in steps. This other transmission line includes a second actuator for the 902 watch, which here operates in a reciprocating motion; this implementation is one, but not the only, possible way of controlling the watch's time setting.

[0183] Subsequently, by means of this second actuator of the watch 902, the clock 100 drives the minute display of the watch 5, in steps of a given value, for example of two minutes, and thus indirectly drives, through the minute display of the watch 5, the hour display of the watch 4, until the display on the watch corresponds to a restart display position which corresponds to the exact instantaneous time which is the value of the instantaneous display visible on the clock 100, increased by at least one additional step, therefore here of two minutes.

[0184] This mechanism functions similarly to a date corrector: watch 200 has a corrector linked to a minute wheel, and clock 100 activates a second actuator on watch 902, which presses this corrector the number of times necessary to reach the current time, plus the increment, here two minutes. This linear movement resembles the operation of a bicycle pump. The reference point on the clock is established in a manner similar to that of a minute repeater mechanism, by probing the hour and minute snail cams typically found on clocks.

[0185] Two-minute increments are a non-limiting example, and in this example, the number of increments to be taken for two-minute increments varies between 0 and 359 increments (60 / 2 * 12). During this phase, the minute wheel of the watch is precisely positioned using a star, specifically, but not exclusively, a 30-toothed star; the advantageous case of a 15-toothed star will be discussed later. More generally, the minute wheel of the 200 watch is precisely positioned by combining a star fixed to the minute wheel and a jumper with one or more teeth. The number of teeth on this star and the number of teeth on this jumper together define the value of the predetermined increment.

[0186] The operation of the first actuator of the 901 watch can be used to ensure the re-cocking of the 402, 701 hammer.

[0187] Subsequently, the 100-second clock awaits the next two-minute interval. At that precise moment, corresponding to the previously set restart display position, the stop lever is released by means of the first pusher, 901, thus allowing the watch to keep accurate time. Thanks to the stop-seconds function, this time setting is highly precise.

[0188] Indeed, this same transition to the following two minutes has the effect of changing the state of the stop control mechanism 120, and of commanding a movement of the start / stop control transmission line, to identify the action of ending the time setting, and to command the transfer of a pulse or a torque to the stop mechanism 20 of the watch 200.

[0189] In the embodiment where the sympathetic clock 100 has a first selection shaft 1 and at least a second drive shaft 2, the watch 200 recognizes the movement of one of the transmission lines in the time-setting end position, the first upper half-shaft 12 re-actuates the stop lever of the stop mechanism 20, which releases the resonator 10 and the watch 200, whose running resumes instantly.

[0190] In summary, through a first interface, the pendulum 100 stops the inertial mass 15, in particular the balance wheel, of the watch 200, in particular by means of a stop-seconds lever mechanism 25.

[0191] Subsequently, by a second mechanism, the clock 100 drives, in steps here in two-minute steps, the minute display of the watch 5 of the watch 200, and through it the hour display of the watch 4 of the watch 200, until these displays together reach and indicate the exact instantaneous time plus two minutes.

[0192] Next, clock 100 waits for the next two-minute interval to release the stop lever, thus allowing watch 200 to run on the correct time.

[0193] The watch is thus set with great precision.

[0194] In summary, the step-by-step process of setting the time on such a friendly 200 watch involves different steps described below. 1A: A predetermined autonomy value is determined for the watch 200 to have at all times after initial winding in the event of the clock 100 being removed. 1B: A predetermined time-setting increment value is determined. 1C: A reference position for the displays 3, 4, and 5 of the watch 200 is defined. 1D: The linking mechanism is equipped with at least two separate transmission lines, one for transferring energy or motion, and the other for selecting a function to be performed or a display value to be adjusted, each transmission line having an interface with a pendulum actuator in the clock 100 and at least one watch actuator in the watch 200.1E: The watch 200 is placed in the receptacle 150, in the transfer position allowing the clock 100 to detect the presence of the watch 200 and to perform an initial winding of the watch 200 to trigger its starting if the watch 200 is stopped when placed on the clock 100. 1F: The clock 100 winds the watch 200 to ensure the predetermined autonomy of the watch 200 when it is removed from the clock 100. 1G: The clock 100 sets the time on the watch 200, either when the watch 200 is placed on the receptacle 150, or at a predetermined time when the clock 100 passes over it, or at the request of a user via a control device 300. that includes the clock 100 or the watch 200, or on order of a clock movement 900 that includes the clock 100.1H: The clock 100 positions a transmission line in a position corresponding to the time setting, and actuates, in successive steps, each by the value of this predetermined step, a transmission line capable of imparting to an internal time-setting mechanism of the watch 200 all the movement necessary to accurately display the current time. 1I: The clock 100 keeps the watch 200 running as long as the watch 200 is on the clock 100, in the receptacle 150, in the transfer position. 1J: More specifically, the clock 100 and / or the watch 200 are equipped with a control means arranged to allow the user to deactivate the time-setting function and the winding function for storing the watch stopped on the clock.1K: More specifically, the time setting is controlled step by step by a periodic mechanism linked to the rotation of the clock's displays 100, or by a user-set alarm mechanism. 1L: More specifically, the assembly 1000 is equipped with a first transmission line comprising a first clock actuator 501, which is arranged to cooperate with a first watch actuator 901 for starting or stopping the watch, and a second transmission line comprising a second clock actuator 502, which is arranged to cooperate with a second watch actuator 902, which incrementally provides the setting movement.1M: More specifically, the assembly 1000 is equipped with a first transmission line comprising a first clock actuator 501, which is arranged to cooperate with a first watch actuator 901 to control the engagement or disengagement of the watch display 200 relative to the resonator without stopping the latter, and a second transmission line comprising a second clock actuator 502, which is arranged to cooperate with a second watch actuator 902, which incrementally provides the positioning movement. 1N: More specifically, a single actuator is provided that constitutes both the first watch actuator 901 and the second watch actuator 902.1O: More specifically, the watch 200 is equipped with a stop mechanism 20, and the clock 100 is equipped with a stop control mechanism 120, which is arranged to transform the step-by-step time-setting command performed by a user or by the clock 100, into a sequence, the first step of which is a control action of the stop mechanism 20 of the watch 200, the stop control mechanism 120 of the clock 100 being arranged to control a movement of a transmission line to identify the time-setting action, and to control the transfer of a pulse or torque to the stop mechanism 20 of the watch 200.1P: More particularly, for the actuation, by successive steps, of the transmission line to the internal time-setting mechanism of the watch 200, a time-setting sequence is carried out according to which the stop control mechanism 120 of the clock 100 commands the stop mechanism 20 of the watch 200 to stop the resonator 10 before performing the time setting, and to command a reset mechanism 500, with which the watch 200 is equipped, to instantly recall the displays 3, 4; 5, of the watch 200 to their reference position, then the advancement of the displays 3, 4, 5 is commanded, by successive steps, to a restart display position which corresponds to the exact instantaneous time readable on the clock 100, increased by a value corresponding to a predetermined step, or an integer number of predetermined steps, imposed by the mechanism.And the passage of the clock 100 to the time corresponding to the restart display position changes the state of the stop control mechanism 120, and commands a movement of the start / stop control transmission line, to identify the end action of the time setting, and commands the transfer of a pulse or torque to the stop mechanism 20 of the watch 200 to release it and restart the resonator 10.1Q: More specifically, to perform the reset, the watch 200 recognizes the movement of the transmission line between the clock 100 and the watch 200 in the time-setting position, and a first actuator of the watch 901 actuates the stop mechanism 20 which stops the resonator 10 and the watch 200, the first actuator of the watch 901 constituting a control mechanism of at least one hammer, to cause the positioning of at least one hour display 4 and one minute display 5, in the reference position, by bringing into cooperation, for each adjusted horological quantity, a hammer 402, 701, with a heart 401, 702, 703, fixed in rotation to a display and carried by a bearing.1R: More specifically, to perform the time-setting sequence, the clock 100 drives another transmission line to impose a particular display on the watch 200. This other transmission line includes a second actuator of the watch 902, which operates in a back-and-forth motion, and, by means of the second actuator of the watch 902, the clock 100 drives the minute display of the watch 5 of the watch 200, by an integer predetermined number of steps, and drives, through the minute display of the watch 5, the hour display of the watch 4 of the watch 200, until the display on the watch 200 corresponds to the restart display position.1S: More specifically, to perform the time-setting sequence, the clock 100 is equipped with a mechanism for driving hour and minute snail cams with movement 900, and a mechanism for instantly displaying the hour and minute, as on a minute repeater mechanism. 1T: More specifically, to perform the time-setting sequence, the clock 100 is equipped with a mechanism for driving a single minute snail cam with movement 900, driven at a speed of one revolution every twelve hours, or one revolution every twenty-four hours, with a number of steps corresponding to the chosen minute step multiplied by 12 or 24, and a mechanism for instantly displaying the minutes, as on a minute repeater mechanism.1U: More specifically, a predetermined two-minute increment is chosen, and the number of increments varies between 0 and 359. During these increments, the minute wheel or dial of watch 200 is precisely positioned using a 30-tooth or 15-tooth star, which can then be the minute wheel itself. 1V: More specifically, the minute wheel or dial of watch 200 is precisely positioned by combining a star attached to the minute wheel or dial with a jumper with one or more teeth. The number of teeth on the star and the number of teeth on the jumper together define the value of the predetermined increment.1W: More specifically, a clock 100 is implemented which includes a first selection shaft 1 and at least a second drive shaft 2, and the watch 200 is arranged to recognize the movement of one of the transmission lines in the time-setting end position, and includes a first upper half-shaft 12 which controls the stop mechanism 20 to release the resonator 10.

[0195] A second variant, called periodic impulse winding and time-setting function, concerns the periodic winding of the watch 200, when the watch is in the receptacle 150 of the clock 100, by a winding value which corresponds to the duration of one period, plus a safety duration.

[0196] The general objectives are the same as for the first step-by-step time-setting variant.

[0197] In an advantageous design, a winding identical to that performed at each period is also triggered when the watch is set, either at the user's request or at the request of the clock's time base 100, to ensure the watch 200 continues to function after the time has been set. This winding is then performed prior to the time-setting operation.

[0198] This principle requires the presence, in the 200 watch, of a safety mechanism, such as a sliding-flange type barrel, to prevent the mainspring from breaking under overload. In a more complex version, a power reserve indicator mechanism can prevent unnecessary or damaging winding of the mainspring.

[0199] For example, and without limitation, periodic winding is carried out with a period of twelve hours, therefore twice a day, for a winding value greater than the periodic winding period, for example a winding value of thirteen hours, so as to have thirteen hours of autonomy.

[0200] The execution of a periodic winding can be done at the user's request at the control means 300, and / or automatically, i.e. controlled by the clock 100, in particular by a mechanism linked to the rotation of the displays 104, 105, of the clock 100. The command performed by the clock 100 can be periodic, or linked to an auxiliary mechanism set by the user, an alarm mechanism, or an alarm-type mechanism; this command performed by the clock 100 is executed only if a watch 200 is present in the receptacle 150, in the transfer position.

[0201] The execution of a periodic winding can be triggered by a user action when requesting a time setting, or by a command from the clock 100 itself for the same purpose.

[0202] More specifically, it is through one of the transmission lines between the clock and the watch, or through a third interface such as a crown, that the clock 100 drives the winding gear of the watch 200 by a number of revolutions equivalent to thirteen hours of power reserve, in this example. This power reserve allows the watch 200 to function if the user immediately puts it on, provided that the watch is equipped with an automatic winding mechanism that ensures the additional winding, even if the watch 200 was unwound beforehand, prior to the time-setting request.

[0203] If the 200 watch is automatic, it will continue winding itself while being worn.

[0204] If the watch 200 remains in its receptacle 150 on the clock 100, it continues to function until the next periodic winding, in our advantageous example, after twelve hours.

[0205] It can be noted that, in an extreme case, the winding may decrease in such a way that the chronometry is impaired, but if the winding period is coupled with a time-setting period, this loss is not detrimental to the user.

[0206] It is also noted that, after approximately 50 cycles, the maximum winding of the watch, for example 60 hours, will be reached, the watch will therefore operate continuously between 48 and 60 hours of winding and the barrel flange is then stressed for a slip of two hours per day, which is much less than for normal wear of an automatic watch, and does not generate unreasonable wear of the mechanism.

[0207] This periodic winding is very simple, and preserves the watch's energy storage mechanism, while ensuring availability for the benefit of the user.

[0208] In summary, the process of winding such a sympathetic 200 watch by periodic impulse involves different steps described below. 2A: A winding period is determined, and when the watch is in the receptacle 150, the watch 200 is periodically wound with a period equal to the winding period, with a winding value corresponding to the duration of one winding period plus a safety time. 2B: More specifically, a winding identical to the periodic winding performed at each winding period is triggered, either during a time-setting operation of the watch 200 by the clock 100, or on demand by a user's action on a control means 300, or by a clockwork movement 900 contained in the clock 100, to ensure the continued operation of the watch 200 after the time-setting operation, the winding being performed prior to the time-setting operation.2C: More specifically, the clock 100 keeps the watch 200 running as long as the watch 200 is on the clock 100, in the receptacle 150, in the transfer position. 2D: The clock 100 and / or the watch 200 are equipped with a control means arranged to allow the user to deactivate the time-setting function and the winding function for storing the stopped watch on the clock. 2E: The watch 200 is equipped with a safety mechanism, a sliding flange barrel or a power reserve measuring mechanism, to prevent the barrel spring from breaking under overload and to prevent unnecessary or damaging winding of the barrel.

[0209] More specifically, a twelve-hour arming period is chosen. 2F: More specifically, a winding value of thirteen hours is chosen, including a twelve-hour winding period and a one-hour safety duration, so as to provide a total of thirteen hours of autonomy. 2G: More specifically, an automatic periodic winding system is chosen, controlled by the clock 100, either periodically by a mechanism linked to the rotation of the clock 100's displays, or by triggering an auxiliary mechanism set by the user, at a time defined by the user in an alarm mechanism or in a similar alarm-type mechanism. 2H: More specifically, a periodic winding system is triggered either by a user action when requesting the time setting, or by a time-setting command from the clock 100.21: The clock 100 drives the winding mechanism of the watch 200 via one of the transmission lines, or via a third interface controlling the rotation of a crown on the watch 200, by a number of turns sufficient to achieve a winding value equal to the sum of the winding period and the safety time, so as to allow the immediate operation of the watch 200, even if the user immediately puts on the watch 200, and even if the watch 200 was previously unwound before the time-setting request. 2J: More specifically, the winding period is reduced to a threshold at which the chronometric accuracy of the watch 200 is impaired, and the winding period is coupled with a time-setting period, so that the loss of chronometric performance is not detrimental to the user. More specifically, the linking mechanism is implemented, comprising at least two distinct transmission lines between the clock 100 and the watch 200.More specifically, this attractive set 1000 is made with a watch 200 comprising at least one resonator 10, and a display gear and a finishing gear, and either a stop mechanism 20 arranged to stop the operation of the resonator 10, or a clutch mechanism allowing the display to be decoupled from the finishing gear, or both such a stop mechanism 20 and such a clutch mechanism, and the watch 200 comprising at least one hour display 4 and one minute display 5. A third variant, called relative time setting, concerns the execution of the time setting on demand, and automatically on a periodic basis, for example twice a day, controlled by the clock 100.

[0210] The general objectives are the same as for the first step-by-step time-setting variant.

[0211] At each period, the clock 100 drives the displays 4 and 5 of the clock 200 backward by a value that ensures the displays move to the 12 o'clock and 0-minute position, for example, a value of 13 o'clock for setting the time on a 12-hour clock. Each of these displays 4 and 5 is held in place at the 12 o'clock and 0-minute reference position by a ratchet. More specifically, this reference position is adjustable, as is the ratchet locking position specific to at least one display 4 or 5, and more specifically, to each display 4 or 5.

[0212] The clock 100 drives the watch displays 4, 5, to the correct time, with an accuracy of approximately ± 20 seconds.

[0213] The execution of this time setting on demand, and automatically on a periodic basis, can be done at the user's request at the level of the control means 300, and / or automatically, that is to say controlled by the clock 100, in particular by a mechanism linked to the rotation of the displays 104, 105, of the clock 100. The command carried out by the clock 100 can be periodic, or linked to an auxiliary mechanism set by the user, an alarm mechanism or an alarm type mechanism; this command carried out by the clock 100 is only executed if a watch 200 is present in the receptacle 150, in the transfer position.

[0214] Through a crown-type or similar interface, the clock 100 drives the minute display of the watch 5, which in turn drives the hour display of the watch 4, in a counterclockwise direction (SIAM) equivalent to thirteen hours, thus ensuring that the hours pass through the reference position, specifically at twelve o'clock and zero minutes. Upon passing through the twelve o'clock and zero minute position, or advantageously upon passing through a nearby position, known as the preparation position, for example, the twelve o'clock and fifteen minute position, a ratchet is released and locks the minute display at the reference position, specifically 12:00. The clock's drive, along the thirteen-hour counterclockwise path, continues via a friction system.This principle is the inverse of the principle which allows the exact setting, to the minute, of the ringing time of an alarm clock, by combining two cams, one which is an hour cam and which has an opening corresponding to a period of time of about a quarter of an hour before the time scheduled for the execution of the ringing, this opening being arranged to cooperate with a pin for the continuation of the drive by the movement of the single minute cam which triggers the ringing at the exact minute set beforehand, as can be read in the document EP2073076B1 in the name of MONTRES BREGUET.

[0215] Subsequently, via a suitable interface, the clock 100 drives the minute display of the watch 5 in the normal clockwise direction (SAM), and through it the hour display of the watch 4, until they reach the correct time. It should be noted that the accuracy of the time setting depends heavily on play and slight variations in the time-setting mechanism; it is estimated at approximately + / - 15 to 20 seconds per minute.

[0216] More specifically, the reference position and / or the preparation position is adjustable, as well as the locking position of at least one ratchet, in particular of each ratchet.

[0217] In summary, the process of setting the relative time of such a sympathetic 200 watch involves different steps described below. 3A: A reference position is defined for the displays 3, 4, and 5 of the watch 200. 3B: The time setting is performed either on demand by a user's action on a control means 300 included in the clock 100 or the watch 200, or automatically and periodically controlled by the clock 100. 3C: To perform the relative time setting, the clock 100 drives the displays 4 and 5 of the watch backward, counterclockwise, with a sufficient travel to ensure that the displays 4 and 5 pass through the reference position. 3D: For a watch 200 displaying the time over twelve hours, a travel greater than twelve hours is chosen, particularly, but not exclusively, for twice-daily time setting.3E: More specifically, the watch 200 is equipped with, notably but not limited to, for each of its displays 4, 5, a ratchet arranged to lock at least one display 4, 5, when it passes into the position corresponding to the reference position. 3F: More specifically, the control means 300 is equipped with an adjustment means to set the locking position of the ratchet specific to at least one display, or to set the locking position of the ratchet specific to each display.

[0218] More specifically, the control means 300 is equipped with an adjustment means to adjust the reference position. 3G: More specifically, we choose a periodic time setting type in automatic, controlled by the clock 100, either periodically by a mechanism linked to the rotation of the displays of the clock 100, or by the triggering of an auxiliary mechanism set by the user, at a time defined by the user in an alarm clock mechanism or in an alarm clock type mechanism. 3H: More specifically, a periodic time setting is triggered either by a user action when requesting a time setting, or by a time setting command from the clock 100. 3I: More specifically, through an interface, the clock 100 drives the minute display of the watch 5, and by this, drives the hour display of the watch 4, in a counter-clockwise direction, to lock the minute display at the reference position, the driving of the hours by the clock 100 continuing on a friction system.3J: More specifically, then, via a suitable interface, the clock 100 drives the minute display of the watch 5, this time in the normal clockwise direction, and thereby the hour display of the watch 4, until they reach the correct time. 3K: More specifically, a ready position is defined, close to the reference position, at the point where a ratchet is unlocked; the control means 300 is equipped with an adjustment means for setting the ready position.3L: More specifically, the assembly 1000 is equipped with a first transmission line comprising a first clock actuator 501, which is arranged to cooperate with a first watch actuator 901 to control the engagement or disengagement of the watch display 200 relative to the resonator 10 without stopping the latter, and a second transmission line comprising a second clock actuator 502, which is arranged to cooperate with a second watch actuator 902, which provides the positioning movement. 3M: More specifically, the watch 200 is equipped with a stop mechanism 20 to hold the inertial mass 15 of the resonator 10 stationary during time setting. 3N: More specifically, the watch 200 is equipped with a clutch mechanism to ensure the starting of the displays 4; 5 without the inertial mass 15 of the resonator 10 being stopped during the time setting.

[0219] In a fourth variant, known as relative time setting, the watch is wound during the thirteen-hour counterclockwise rotation of the relative time setting mechanism described above. This winding occurs automatically twice a day, on demand. The thirteen-hour counterclockwise rotation of displays 4 and 5 ensures the watch is wound for a period of thirteen hours.

[0220] This fourth variant allows for time setting and winding with a single rotating interface.

[0221] The time-setting function is triggered by a user action on the clock (on demand), or by a mechanism linked to the rotation of the clock displays (periodic).

[0222] Through a crown-type or similar interface, the clock 100 drives the minute display of the watch 5 and the hour display of the watch 4 counterclockwise by the equivalent of thirteen hours for relative time setting. This rotation can be used to wind the mainspring barrel, advantageously by thirteen hours.

[0223] Two solutions are proposed: either the interface drives, in addition to the counter-clockwise rotation of the displays, the manual winding mechanism; or the finishing mechanism includes a ratchet mechanism, which allows the barrel to be wound during the counter-clockwise rotation of the displays.

[0224] The first option is simple to implement. It includes a ratchet system so that the relative time setting displays can rotate clockwise, but the ratchet system is not located in the finishing gear.

[0225] The second option is interesting because it requires only a ratchet wheel in the finishing gear train. The setting friction must allow the transfer of torque from the winding mechanism; the typical winding torque is approximately 1 N·mm, and the typical winding torque for maximum winding is 3 N·mm. A clutch system can replace the conventional setting friction.

[0226] This invention makes it possible to ensure winding for a period of thirteen hours when setting the time on demand, and for a period of thirteen hours for periodic time setting.

[0227] In summary, the process of rewinding such a sympathetic 200 watch by relative time setting involves different steps described below. 4A: A reference position is defined for the displays of the watch 200. 4B: Winding is performed either by setting the time, or on demand by a user's action on a control means 300 located on the clock 100 or the watch 200, or automatically and periodically controlled by the clock 100. To perform the relative time setting that enables winding, the clock 100 drives the displays 4 and 5 of the watch backward, counterclockwise, with a sufficient travel to ensure that the displays 4 and 5 pass through the reference position. 4C: More specifically, for a watch 200 displaying the time over twelve hours, a travel greater than twelve hours is chosen, particularly, but not exclusively, for twice-daily time setting.4D: More specifically, the watch 200 is equipped with, for each of its displays 4, 5, a ratchet arranged to lock that display 4, 5 when it passes into the position corresponding to the reference position. 4E: More specifically, the control means 300 is equipped with an adjustment means for setting the locking position of the ratchet specific to at least one display, or for setting the locking position of the ratchet specific to each display. 4F: More specifically, the control means 300 is equipped with an adjustment means for setting the reference position. 4G: More specifically, a periodic automatic time setting is chosen, controlled by the clock 100, either periodically by a mechanism linked to the rotation of the displays of the clock 100, or by triggering an auxiliary mechanism set by the user, at a time defined by the user in an alarm or alarm-type mechanism.4H: More specifically, a periodic time setting is triggered, either by a user action when requesting a time setting, or by a time setting command from the clock 100. 41: More specifically, through an interface, the clock 100 drives the minute display of the watch 5, which in turn drives the hour display of the watch 4, counterclockwise, to lock the minute display at the reference position. The hour display driven by the clock 100 continues via a friction system to ensure the defined winding. In particular, a preparation position is defined, close to the reference position, upon passing through which the pawl is unlocked, thus locking the minute display. 4J: More specifically, when the displays are rotated counter-clockwise, the interface winds the barrel.Either the ratchet is external to the finishing gear train and the interface drives, in addition to the displays, the manual winding gear train of the 200 watch, or the finishing gear train has a ratchet mechanism that allows the barrel to be wound by the display gear train and the part of the finishing gear train located between the ratchet mechanism and the barrel during the reverse rotation of the displays.

[0228] In a fifth variant, called permanent time setting, the time setting, like the winding, only takes place on demand.

[0229] In this variant, the watch 200 is necessarily equipped with a stop mechanism 20, arranged to stop the operation of the resonator 10, notably by the pressure of an arm, or a leaf spring, or another actuator, on the inertial mass 15 or on a suitable element of the resonator. More specifically, this stop mechanism 20 is a stop-seconds mechanism 25 comprising a stop lever.

[0230] The stop lever is activated.

[0231] The clock moves the displays back by thirteen hours; they are blocked when passing the reference position, in particular 12:00, by ratchets.

[0232] These thirteen hours of reverse rotation also ensure the winding of the watch as before.

[0233] The clock then drives the displays to the correct time, with an accuracy of approximately ± 20 seconds.

[0234] Next, the clock continues to drive the displays until the watch is unlocked on the clock.

[0235] Unlocking the watch on the clock releases the stop lever.

[0236] This fifth variant avoids constant operation of the watch (outside of display), daily winding and time setting, the functions being performed only once, from the request until the watch is taken.

[0237] The time-setting function is triggered by a user action on the clock (on demand) only.

[0238] Through a second interface (push-button type), the clock stops the watch and disengages the display (road clutch).

[0239] Through a first interface (crown-type), the clock drives the minute display, and consequently the hour display, counterclockwise by the equivalent of thirteen hours, thus ensuring the hour display reaches the reference position, specifically 12:00, and guaranteeing a minimum winding of more than twelve hours of power reserve, particularly with a thirteen-hour power reserve, similar to the fourth variant. Shortly before reaching the reference position, specifically 12:00, in reverse, for example, when passing the 12:15 position, or similar, a ratchet unlocks and locks the minute display at the reference position, specifically 12:00; the clock's counterclockwise drive of the thirteen hours continues via a friction system.

[0240] Subsequently, through the first interface, the clock drives the minute display, and through it the hour display, until they reach the correct time. It should be noted that the accuracy of the time setting depends heavily on play and irregularities in the time-setting mechanism; it is estimated at ±20 seconds per minute.

[0241] Subsequently, via the first interface, the clock drives the displays at real speed until the watch is unlocked from the clock for wearing.

[0242] When the watch is unlocked for wear by the user, the clock, via the second interface, releases the stop lever and the clutch of the display, the watch is once again independent.

[0243] This invention has the advantage of saving wear and tear on the watch's operation when it is on the clock.

[0244] It also guarantees a minimum of thirteen hours of battery life regardless of when the watch is taken.

[0245] In summary, the process of winding such a sympathetic 200 watch by permanent time setting involves different steps described below. 5A: A reference position is defined for the displays of the watch 200. 5B: The time setting is performed only on demand by action of a user on a control means 300 which includes the clock 100 or the watch 200, or automatically periodically controlled by the clock 100, and, to perform the time setting, the clock 100 drives the displays 4, 5, of the watch backwards, in a counter-clockwise direction, with a stroke large enough to guarantee that the displays 4, 5, pass through the reference position; or the clock 100 controls means of the watch 200 which are arranged so as to ensure the movement of the displays towards the reference position by means of cores.5C: Through an interface, the clock 100 drives the minute display of the watch 5, which in turn drives the hour display of the watch 4, counterclockwise, to lock the minute display in the reference position. The hour display driven by the clock 100 continues via a friction system, and then, through a suitable interface, the clock 100 drives the minute display of the watch 5, this time clockwise, and through it, the hour display of the watch 4, until they reach the correct time in continuous rotation. More specifically, a preparation position is defined, close to the reference position, at which point a ratchet is unlocked to lock the minute display.5D: The user's action on the control means 300 activates the stop mechanism 20 to stop the operation of the resonator 10, prior to the drives of the displays 4, 5, to the reference position, and, after the instantaneous time reached by the displays 4, 5, of the watch 200, the clock 100 drives the displays 4, 5, as long as the watch 200 is in the transfer position in the receptacle 150, and the removal of the watch 200 from the receptacle 150 dissociates it from the clock 100 and generates the release of the stop mechanism 20 to allow the operation of the resonator 10. 5E: The drives of the displays 4, 5, to the reference position, in a counter-clockwise direction. 5F: When the user acts on the control means 300, the pendulum 100 actuates the stop mechanism 20 through an on / off interface to stop the operation of the resonator 10.5G: More specifically, for the reverse drive of displays 4 and 5, the clock 100 drives displays 4 and 5 via a motion transmission interface. After displays 4 and 5 reach the current time in a normal clockwise direction, the clock 100 drives displays 4 and 5 at full speed as long as the watch 200 is in the transfer position in the receptacle 150. Removing the watch 200 from the receptacle 150 disengages it from the clock 100 and disengages the connection between the motion transmission interface and displays 4 and 5. 5H: More specifically, for a watch 200 displaying the time over twelve hours, a travel with a value greater than twelve hours is selected, particularly, but not exclusively, for twice-daily time setting.5I: More specifically, the watch 200 is equipped with, for each of its displays 4, 5, a ratchet arranged to lock that display 4, 5 when it passes into the position corresponding to the reference position. 5J: More specifically, the control means 300 is equipped with an adjustment means for setting the locking position of the ratchet specific to at least one display, or for setting the locking position of the ratchet specific to each display. 5K: More specifically, the control means 300 is equipped with an adjustment means for setting the reference position. 5L: More specifically, a permanent automatic time-setting trigger is chosen, controlled by the clock 100, either periodically by a mechanism linked to the rotation of the displays of the clock 100, or by triggering an auxiliary mechanism set by the user, at a time defined by the user in an alarm-type mechanism.5M: More specifically, such permanent time setting is triggered either by a user action when a time setting request is made, or by a time setting command from the clock 100. 5N: More specifically, the control means 300 is equipped with an adjustment means for setting the ready position. 5O: More specifically, the winding is performed only on demand when a user acts on the control means 300 during the permanent time setting that enables winding.

[0246] A sixth variant, called data acquisition for on-demand time setting, aims to allow the time displayed by the clock to be read and the information transmitted to the watch within the framework of the sympathetic clock operating modes described in the first, third, and fifth variants above. figures 8 to 12 illustrate this data collection on the clock for time setting on demand.

[0247] This sixth variant uses a mechanism that reads the difference between the current time and the reference time, arbitrarily chosen (and not limited to) 12:00 for all the variants described. It also transmits this difference to the watch, allowing it to be indexed after its displays are reset to the reference position, specifically 12:00. Advantageously, this transmission can provide either the exact difference or the sum of the difference and an offset necessary for setting the time to the second.

[0248] This sixth variant is presented here in a manner analogous to the first variant, known as step-by-step time setting; we will see that it is also valid for the third and fifth variants.

[0249] Recall that, according to the first variant, the time-setting function is triggered by a user action on the clock (on demand at the control means 300) or by a mechanism linked to the rotation of the clock's displays (periodic). Through the first interface, the clock stops the resonator 10, specifically the balance wheel 15 of the watch (balance wheel stop lever mechanism), and actuates a hammer mechanism that returns the hour display of the watch 4 to 12 o'clock, and consequently the minute display of the watch 5 to 00 minutes. Then, through the second interface (pusher), the clock advances the minute display of the watch 5, and consequently the hour display of the watch 4, in two-minute increments, until these displays 4 and 5 reach and indicate the correct time plus an unlimited two-minute increment. This function can also reset the hammer.During this phase, the minute wheel is positioned precisely using a star, specifically a 30-tooth or 15-tooth star.

[0250] Next, the clock waits for the next two-minute interval to release the stop lever and allow the watch to keep time.

[0251] A first embodiment of this sixth variant includes a single cam 601 at the level of the clock 100, and performs the time setting step by step.

[0252] The clock 100 has a snail cam 601 that makes one revolution every twelve hours and has 360 bearings 6010 around its circumference, or one bearing every two minutes. This cam is integral to the clock's display (one revolution every twelve hours).

[0253] The clock 100 includes a feeler 602, specifically a rocker, which has a rack 603 at one end and a feeler finger 604 with a beak 605 at the opposite end. The latter is held by default in a rest position, which corresponds to the reference time plus an offset to account for any gear play and a possible additional jump to enable the stop-seconds function according to the first variant. This feeler 602 is advantageously held in place by an adjusting eccentric (not shown), allowing the watchmaker to easily compensate for this play.

[0254] The adjustment can also advantageously be carried out with a fine adjustment rake according to the teachings of application EP20158326.7 in the name of MONTRES BREGUET.

[0255] When the user requests the time setting, or when the clock itself requests this time setting, the proposed time setting cycle includes a phase of setting the watch to the reference position, 12:00 for example.

[0256] The probe 602 carrying the probe finger 604 is subjected to the action of return means, and in particular of an elastic return means such as a spring.

[0257] As soon as this reference setting is completed, the clock 100 releases the feeler 602, which is then rotated by this return mechanism, not shown in the figures. The feeler 602 rotates until it comes to rest against one of the 360 ​​bearings 6010 of the cam 601. This rotation corresponds exactly to the number of two-minute steps separating the reference time from the time displayed on the clock.

[0258] This rotation is transmitted, without limitation, via an interface, notably a back-and-forth type, to the watch and its display or minute display. In a variant, the interface may also be rotary instead of back-and-forth.

[0259] At the end of its function, the clock 100 resets and returns the feeler 602 to its rest position by a mechanism similar to the known mechanisms of grande sonnerie, and is ready for a new function.

[0260] A second embodiment of this sixth variant includes two cams 610 and 620 in the clock 100, and performs the time setting step by step.

[0261] A 360-position cam, such as the one used in the first embodiment, remains in fact a difficult element to manufacture, and necessarily bulky, even in the context of a clock.

[0262] The operation of this second embodiment is analogous to that of the first single-cam embodiment, but compensates for the difficulty of manufacturing the cam: thus, the clock 100 has two cams: a first hour cam 610 making one revolution every twelve hours and having on its circumference 12 bearings 6100 of one hour each, and a second minute cam 620 making one revolution every hour and having 30 bearings 6200 of two minutes each. These cams are integral to the clock's display, respectively to the hour display 104 (one revolution every twelve hours) and the minute display 105 (one revolution every hour).

[0263] The 100 clock also has two feelers: a first feeler 630 arranged to cooperate with the first hour cam 610, and a second feeler 640 arranged to cooperate with the second minute cam 620. These two feelers are held by default in a rest position which corresponds, for the first hour feeler 630 to the reference time plus an offset corresponding to possible gear play, and for the second minute feeler 640 to a possible additional jump to allow the time-setting function with a stop-seconds mechanism 25 according to the first variant.

[0264] As soon as watch 200 has been set to the reference time, clock 100 releases feelers 630 and 640 until they come into contact with their respective cams 610, 620.

[0265] This rotation is transmitted to an interface and to the watch 200, notably via a differential gear train 680, one of whose ratios is 1 / 12 relative to the other, in order to combine the values ​​of the two cams. An output of this differential mechanism 680 is arranged to drive a second actuator 502, notably but not exclusively via a second control cam 684.

[0266] More particularly, this second actuator 502 includes a crank and a connecting rod arranged to push and pull a second control rod 512 which is included in this second actuator 502, so as to impart to the second control rod 512 a back-and-forth movement for setting the time of such a watch 200. In a variant, the second control rod 512 is returned to the second cam 684 by second elastic return means 513.

[0267] In one variant, the pendulum 100 includes at least one electromechanical or electronic movement, which is arranged to control the movement of an output mobile which is arranged to drive such a second actuator 502, in particular but not limited to via a second control cam 684.

[0268] This rotation is transmitted via this interface to the 200 watch and its 5 minute display.

[0269] At the end of its function, the clock 100 resets and returns the two feelers 630 and 640 to their rest positions, by a mechanism similar to the known mechanisms of grande sonnerie, and is ready for a new function.

[0270] In summary, the process of taking data from clock 100 for setting the time on demand of watch 200 involves different steps described below. 6A: A reference position is defined for the displays of the watch 200. 6B: The clock 100 sets the time on the watch 200, either when the watch 200 is placed on the receptacle 150, or when the clock 100 passes over a predetermined time, or at the request of a user via a control 300 on the clock 100 or the watch 200, or upon command from a clockwork mechanism 900 in the clock 100. The time displayed by the clock 100 is then read to transmit the time information to the watch 200. This is achieved by implementing a reading mechanism in the clock 100, which reads the difference between the current time and the reference time and is configured to transmit the value of this difference to the watch. 200, so as to index it after its displays 4, 5, 6C have been set to their reference position: More specifically,The reading mechanism is arranged to transmit the information of the value, or of the exact deviation, or of a corrected deviation which is the sum of the deviation and an offset necessary for setting the time to the second. 6D: More specifically, a predetermined time-setting step value is determined, and the clock 100 positions a transmission line in a position corresponding to the time setting, and actuates, in successive steps, each corresponding to the predetermined step value, a transmission line capable of imparting to an internal time-setting mechanism in the watch 200 all the movement necessary to accurately achieve the display of the current time. And, for the successive-step actuation of the transmission line to the internal time-setting mechanism in the watch 200,A time-setting sequence is performed whereby the stop control mechanism 120 of the clock 100 commands the stop mechanism 20 of the watch 200 to stop the resonator 10 or disengage the finishing gear of the display gear before setting the time, and to command a reset mechanism 500 in the watch 200 to instantly return the displays 3, 4, 5 of the watch 200 to their reference position. 6E: Then, the displays 3, 4, 5 are advanced in successive steps until they reach a restart display position that corresponds to the exact instantaneous time readable on the clock 100, plus a value corresponding to a predetermined step, or a whole number of predetermined steps, imposed by the mechanism. 6F: Then, the transition of the clock 100 to the time corresponding to the restart display position modifies the state of the stop control mechanism 120,and commands a movement of the start / stop control transmission line, to identify the end action of the time setting, and commands the transfer of a pulse or torque to the stop mechanism 20 of the watch 200 to release it and restart the resonator 10 or engage the finishing gear to the display gear. 6G: More specifically, to perform the reset, the watch 200 recognizes the movement of the transmission line between the clock 100 and the watch 200 in the time-setting position, and a watch 200 is used in which a first actuator of the watch 901 actuates the stop mechanism 20 which stops the resonator 10 and the watch 200, this first actuator of the watch 901 constituting a control mechanism of at least one hammer, to cause the positioning of at least one hour display 4 and one minute display 5, in the reference position, by cooperation, in particular for each adjusted clock quantity,of a hammer 402, 701, with a core 401, 702, 703, fixed in rotation to one of the displays, and more particularly but not limited to being carried by a roadway. 6H: More specifically, to perform the time-setting sequence, the clock 100 drives another transmission line to impose a particular display on the watch 200. This other transmission line includes a second actuator for the watch 902, which is fitted to the watch 200 and operates in a back-and-forth motion. By means of this second actuator of the watch 902, the clock 100 drives the minute display of the watch 5 on the watch 200, by a predetermined integer number of steps, and drives, via the minute display of the watch 5, the hour display of the watch 4 on the watch 200, until the display on the watch 200 corresponds to the restart display position. 6I: More specifically, to perform the time-setting sequence,The clock 100 is equipped with a mechanism for driving hour and minute snail cams by the movement 900, and with a mechanism for instantly displaying the hour and minute on demand. 6J: More specifically, to perform the time-setting sequence, the clock 100 is equipped with a mechanism for driving a single minute snail cam driven at a speed of one revolution every twelve hours, or one revolution every twenty-four hours, by the movement 900, having a number of steps corresponding to the chosen minute step multiplied by 12 or 24, and with a mechanism for instantly displaying the minutes. 6K: More specifically, a predetermined two-minute interval is selected, and the number of intervals to be taken varies between 0 and 359. During this time, the minute track or wheel of the 200 watch is precisely positioned using a 30-tooth or 15-tooth star wheel, which can then be formed by the minute track itself. 6L: More specifically,The minute wheel or carriage of the 200 watch is precisely positioned by the combination of a star attached to the minute wheel or carriage, and a jumper with one or more teeth, the number of teeth of the star and the number of teeth of the jumper together defining the value of the predetermined pitch. 6M: More specifically, when the clock 100 drives the minute display of the watch 5, it also ensures the resetting, at least partially, of at least one hammer 402, 701, or of each hammer 402, 701. 6N: More specifically, to perform the instantaneous hour and minute feel, a clock 100 is used which includes a single snail cam 601 making one revolution every twelve hours, and having three hundred and sixty bearings 6010 on its circumference, i.e., one bearing every two minutes, the single snail cam 601 being integral with the display of the clock 100 which makes one revolution every twelve hours, and the clock 100 includes a feeler 602,subjected to the action of elastic return means, and which comprises at a first end a rake 603, and at a second opposite end a feeler finger 604 with a beak 605, which feeler 602 is held by default in a rest position, which corresponds to the reference time, plus a positive or zero offset corresponding to possible gear play and a possible additional jump to allow for a time-setting function with stop seconds, and, when the user requests the time setting, or when the clock 100 requests the time setting, the time-setting cycle begins with a phase of referencing the clock 100 to the reference position, and, as soon as this referencing is carried out, the clock 100 releases the feeler 602, which rotates until it comes to rest on one of the bearings 6010 of the cam 601,according to a rotation which corresponds exactly to the number of steps separating the reference time from the time displayed on the clock 100. 6O: More specifically, at the end of the function, the clock 100 resets and returns the feeler 602 to its rest position, and is ready for a new function. 6P: More specifically, to perform the instantaneous hour and minute touch-up, a clock 100 is used which includes a first hour snail cam 610 making one revolution in twelve hours and having on its circumference twelve bearings 6100 of one hour each, and a second minute snail cam 620 making one revolution in one hour and having thirty bearings 6200 of two minutes each, which cams 610 and 620 are respectively fixed to the hour display of the clock 104 making one revolution in twelve hours and to the minute display of the clock 105 making one revolution in one hour,the clock 100 comprising a first feeler 630 arranged to cooperate with the first hour cam 610, and a second feeler 640 arranged to cooperate with the second minute cam 620, the first feeler 630 and the second feeler 640 being held by default in a rest position which corresponds, for the first hour feeler 630 to the reference time plus a positive or zero offset corresponding to any gear train play, and for the second minute feeler 640 to a possible additional jump to allow the time-setting function with a stop-seconds mechanism 25, and, when the user requests the time setting, or when the clock 100 requests the time setting, the time-setting cycle begins with a phase of referencing the clock 200 to the reference position, and, as soon as this referencing is carried out,The clock 100 releases the first feeler 630 and the second feeler 640 until they come into contact with their respective cams 610 and 620, in a rotation which is transmitted to an interface and to the minute display 5 of the watch 200, via a differential gear 680, one of whose ratios has a ratio of 1 / 12 to the other, in order to combine the values ​​of the two cams 610 and 620. 6Q: More specifically, at the end of its function, the clock 100 resets and returns the first feeler 630 and the second feeler 640 to their rest position, and is ready for a new function.

[0271] A seventh variant, known as the display reference time setting, and illustrated by the figures 13 to 18 , proposes a solution for the function of returning to the reference position, specifically 12:00, of the 200 watch displays, a function which is necessary for the implementation of the first, third, and fifth variants above.

[0272] The aim is to enable the execution of a cycle, for a first movement of an interface between the watch 200 and the clock 100, a corrector for example, to perform the following functions in the watch 200 at any time: disengage the display gear from the finishing gear; bring the displays to a reference position, for example 12:00; maintain this position as precisely as possible; enable a time-setting function (which will be detailed later); take advantage of this time-setting function to reset a hammer; or deactivate this hammer.

[0273] On a second movement of the interface between watch 200 and clock 100: Engage the display gear with the finishing gear; if necessary, reset the hammer.

[0274] To this end, the 200 watch includes: a hammer 701, analogous to a chronograph hammer, which has an armed position where it is held by a ratchet and tensioned by a spring, and an active position where it comes to bear on the periphery of a first hour cam 702, in the shape of a heart, so as to constrain it in rotation to its smallest radius; this first hour cam 702, in the shape of a heart, is similar to those used in chronograph mechanisms.This first hour cam 702 is carried by the hour wheel 708; a second minute cam 703 in the shape of a truncated heart, carried by the minute display 705; a jumper 704 cooperating in support with a 30-toothed star attached to the minute display (not shown in the figures); a 30-toothed star carried by the minute display (not shown in the figures); a road wheel pinion 705, which can act as a star, in particular a 15-toothed star cooperating with a double jumper 7040, as seen on the . figure 17 ; a clutch mechanism 706 between the display gear 705-707-708 and the finishing gear 710, comprising a friction spring 709 in the particular case illustrated by the figures; a control mechanism for the three phases of the function (not shown in the figures).

[0275] The cycle takes place in three phases: triggering the setting to the reference position, specifically 12:00, and disengaging via the interface, in the position of the figure 15 ; maintaining the position of the displays for time setting, isolation or hammer resetting; clutching and, if necessary, resetting the hammer via the interface.

[0276] During the first phase, the interface actuates the 706 clutch to its disengaged position, as seen on the figure 16 .

[0277] The interface then releases the hammer 701, which, via the first heart cam 702, moves the hour display and, via the timer, the minute display to the reference position, specifically 12:00.

[0278] The typical timer set allows for an error of approximately 3 minutes in the position of the minute display relative to the hour display: ±1.5 minutes, depending on the direction of the zeroing transmitted by the hammer on the heart, as visible on the Figures 13 and 14 .

[0279] Advantageously, an additional minute-heart cam 703 works at the end of the function of the hammer 701, and guarantees the position to the minute.

[0280] During the second phase, the 704 jumper and the 30-tooth star maintain the display position at the reference position, specifically 12:00, and at all subsequent positions in two-minute correction increments. In our example, the 15-tooth chain advantageously replaces the 30-tooth star, working with a double jumper as shown in the diagram. figure 17 .

[0281] The mechanism can reset the hammer without loss of display, the time can be set in two-minute increments.

[0282] During the third phase, the interface can release the clutch, and reconnect the finishing gear with the display gear.

[0283] Thus, the option of two core cams improves the precision of the operation.

[0284] There figure 18 illustrates a BREGUET 1050 chronograph clutch mechanism, comprising a clamp 721 whose function is to ensure the clutching and disengagement, under the control of a column wheel 740 which controls the angular separation of the clamp arms 721 and 722, for the opening or closing of the clamp, and therefore the disengagement or the clutching.

[0285] This seventh variant allows for the use of a time-setting mechanism, and allows the display gear to be disengaged from the finishing gear, and for them to be re-engaged with each other.

[0286] The construction is simplified in the case of the advantageous use of the road toothing for the star function.

[0287] In summary, the process of setting the reference time of the displays involves different steps described below. 7A: A reference position for the displays is defined. 7B: A watch 200 is used, comprising a clutch mechanism 706 between a display gear 705, 707, 708, and a finishing gear 710, and comprising a hammer 701 movable between an armed position where it is held by a ratchet and tensioned by a spring, and an active position where the hammer 701 is arranged to bear against the periphery of a first hour cam-heart 702 carried by an hour wheel 708 of the watch 200, so as to constrain the rotation of the first hour cam-heart 702 to its smallest radius.

[0288] And we execute a cycle comprising three phases: 7C: a first phase during which, by a first movement of an interface between the clock 100 and the watch 200, the clutch mechanism 706 is disengaged by the interface that actuates it towards its disengaged position, and, after disengagement of the clutch 706, the interface releases the hammer 701, which drives, via the first hour cam 702, the hour display 4, and, via the timer, the minute display 5 towards the reference position; 7D: a second phase where the position of the displays 4, 5, is maintained, for setting the time, isolating or resetting the hammer 701; 7E: and a third phase where, by a second movement of the interface between the clock 100 and the watch 200, to reconnect the finishing gear with the display gear, the clutch mechanism 706 is engaged by the interface which actuates it towards its engaged position and during which third phase it is possible to reset the hammer 701 via the interface. 7F: More specifically, at the end of the hammer's travel, the hammer 701 engages with a second truncated heart-shaped minute cam 703, which is integral with the minute display 5, to guarantee the position to the nearest minute. 7G: More specifically, a predetermined time-setting step value is determined, and, during the second phase, the display is held in the reference position by a jumper 704 and a star on the watch 200, and then in each subsequent position step by step, to allow the hammer 701 to be reset without loss of the display. 7H: More specifically, the star on the minute display 5 is chosen to be either a thirty-toothed star that engages with a single-tooth jumper 704, or a fifteen-tooth minute wheel pinion that engages with one tooth at a time on a double jumper 7040 with two teeth.71: More specifically, the minute wheel or dial of the watch 200 is precisely positioned by combining a star attached to the minute wheel or dial with a jumper having one or more teeth. The number of teeth on the star and the number of teeth on the jumper together define the predetermined pitch. 7J: More specifically, the clutch mechanism 706 is equipped with a friction spring 709. 7K: More specifically, a chronograph clutch mechanism 706 is used, comprising a clamp 721 whose function is to engage and disengage the clutch. This mechanism is controlled by a column wheel 740, which adjusts the angular separation of the arms of the clamp 721, 722, for opening or closing the clamp, corresponding respectively to disengaging or engaging the clutch. 7L: More specifically, a three-phase control mechanism is used.More specifically, this control mechanism includes at least one 740 column wheel.

[0289] As an alternative to this seventh variant, an eighth variant, known as the reference time setting, is illustrated by the figures 19 to 21 , proposes another solution for the function of returning to the reference position, specifically 12:00, of the 200 watch displays, a function which is necessary for the implementation of the first, third, and fifth variants above.

[0290] Here too, the aim is to allow the execution of a cycle, for a first movement of an interface between the watch 200 and the clock 100, a corrector for example, to perform the following functions in the watch 200 at any time: disengage the display gear from the finishing gear; bring the displays to a reference position, for example 12:00; maintain this position as precisely as possible; enable a time-setting function (which will be detailed later).

[0291] And, on a second movement of the interface between the watch and the clock, engage the display gear with the finishing gear.

[0292] We use a 200 watch which includes: a rake 823 geared onto an hour wheel 808 attached to the time display of the watch 4, and carrying an hour cam 802 having a wolf's tooth notch, a ratchet 801 which is held against the hour cam 802 by a ratchet spring 8010, where the rake 823 is arranged to unclip clockwise from the hour wheel 808, and is driven by a return spring 825.

[0293] The watch 200 still has a rack pinion 824 or hour pinion, which rack pinion 824 is arranged to drive and wind the rack 823, which clicks at each tooth, during normal operation of the watch 200 when the watch 200 does not cooperate with the clock 100.

[0294] The 200 watch still includes a clutch mechanism 806 between a display gear 805; 807; 808 and a finishing gear 810.

[0295] And, at any given time, the reference time of the 200 watch is set by a cycle comprising three phases, consisting of: A first phase during which the reference position is triggered by an initial movement of an interface between the clock 100 and the watch 200. The reference time of the displays 4 and 5 of the watch 200 is set, and the clutch mechanism 806 is disengaged by the interface that actuates it towards its disengaged position. This allows the rack 823 to drive the hour and minute display gear of the watch 200 counterclockwise for as many revolutions as necessary until the pawl 801 encounters the toothed opening of the hour cam. This locking corresponds to the reference display position. A second phase where the position of the displays 4 and 5 is held for time setting, and where the time-setting mechanism controlled by the clock 100 sets the time. displays 4, 5,of the watch 200 in a clockwise direction towards the exact time by resetting the rack 801, and a third phase where, by a second movement of the interface between the clock 100 and the watch 200, to reconnect the finishing gear with the display gear, the clutch mechanism 806 is engaged by the interface which actuates it towards its engaged position and during which third phase it is possible to reset the rack 801 or to complete the resetting of the rack 801, begun during the second phase, by the interface.

[0296] More specifically, a watch 200 is used, comprising a watch hour display 4 carrying an hour cam 802 having an opening 8020, a second minute cam 803 carried by the minute display of the watch 805, and having a wolf's tooth opening 8030 or a notch 831.And the clutch mechanism 806 is disengaged in its disengaged position, which allows the rake 823 to drive the hour and minute display gear of the watch 200 counterclockwise, over as many turns as necessary, until the pawl 801 meets the opening 8020 of the first hour cam 802, corresponding to the minutes preceding the reference time, at a time when the pawl 801 can bear on the second minute cam 803 for the rotation corresponding to the last minutes before reaching the reference time, and until it locks in the toothed opening 8030 of the second minute cam 803, the lock corresponding to the reference display position.

[0297] The 200 watch still features a jumper 804 arranged to cooperate with a star, specifically a 30-tooth star attached to the minute display wheel 805, similarly to the seventh variant, and includes a mechanism controlling the three phases of the function

[0298] The cycle thus takes place in three phases: triggering the setting to the reference position, in particular 12:00, and disengaging via the interface; maintaining the position of the displays for setting the time; engaging, and if necessary resetting the 801 ratchet via the interface.

[0299] During normal watch operation, excluding sympathetic functions, the hour pinion 824 drives and winds the ratchet 823, which disengages with each tooth, as visible on the figures 19 And 20 .

[0300] During the first phase, the interface actuates the 806 clutch to its disengaged position, as seen on the figure 21 .

[0301] The clutch releases the hour display gear and the minute display, which is driven counterclockwise by the 823 rack.

[0302] The display gear, driven counterclockwise by the 823 rack, can potentially make more than one revolution of the hour wheel (hour display), and more than twelve revolutions of the roadway (minute display) linked by the timer.

[0303] During the second phase, the time-setting mechanism can perform its function clockwise to the correct time by resetting the 801 rack. If the resetting is not complete by setting the time, it is completed by the normal clockwise rotation of the watch display.

[0304] During the third phase, the interface can release the clutch, and reconnect the finishing gear with the display gear.

[0305] In summary, the process of setting the reference time involves several steps described below. 8A: A reference position for the displays is defined. 8B: A watch 200 is used comprising: a rack 823 meshed with an hour wheel 808 attached to the hour display of the watch 4, and carrying an hour cam 802 having a wolf's tooth notch, a ratchet 801 which is held against the hour cam 802 by a ratchet spring 8010, where the rack 823 is arranged to unclick in a clockwise direction from the hour wheel 808, and is driven by a return spring 825.

[0306] The watch 200 still has a rack pinion 824 or hour pinion, which rack pinion 824 is arranged to drive and wind the rack 823, which clicks at each tooth, during normal operation of the watch 200 when the watch 200 does not cooperate with the clock 100.

[0307] The 200 watch still includes a clutch mechanism 806 between a display gear 805; 807; 808 and a finishing gear 810.

[0308] And, at any given time, the reference time of the 200 watch is set by a cycle comprising three phases, consisting of: 8C: a first phase during which the reference position is triggered by an initial movement of an interface between the clock 100 and the watch 200. The reference time of the displays 4 and 5 of the watch 200 is set, and the clutch mechanism 806 is disengaged by the interface that actuates it towards its disengaged position. This allows the rack 823 to drive the hour and minute display gear of the watch 200 counterclockwise, for as many revolutions as necessary, until the pawl 801 encounters the toothed opening of the hour cam. This locking corresponds to the reference display position. 8D: a second phase where the position of the displays 4 and 5 is maintained for time setting, and where the time-setting mechanism controlled by the clock... 100 sets the time on displays 4, 5,of the watch 200 in a clockwise direction towards the exact time by resetting the rack 801, 8E: and a third phase where, by a second movement of the interface between the clock 100 and the watch 200, to reconnect the finishing gear with the display gear, the clutch mechanism 806 is engaged by the interface which actuates it towards its engaged position and during which third phase it is possible to reset the rack 801 or to complete the resetting of the rack 801, begun during the second phase, by the interface. , 8F: More specifically, a predetermined time-setting step value is determined, and, during the second phase, the display position is maintained in the reference position by cooperation between a jumper 804 and a star on the watch 200, and then in each subsequent position step by step, to allow the resetting of the rack 801 without loss of the display. 8G: More specifically, the star on the minute display 5 is chosen to be either a thirty-toothed star cooperating with a single-tooth jumper 804, or a fifteen-tooth minute wheel pinion cooperating with one tooth at a time of a double jumper 8040 with two teeth.8H: More specifically, the minute wheel or dial of the watch 200 is precisely positioned by combining a star attached to the minute wheel or dial and a jumper with one or more teeth. The number of teeth on the star and the number of teeth on the jumper together define the predetermined pitch. 8I: More specifically, the clutch mechanism 806 is equipped with a friction spring 809. 8J: More specifically, a chronograph clutch mechanism 806 is used, comprising a clamp 821 whose function is to engage and disengage the clutch. This is controlled by a column wheel 840, which adjusts the angular separation of the arms of the clamp 821, 822, for opening or closing the clamp, corresponding respectively to disengaging or engaging the clutch. 8K: More specifically, a three-phase control mechanism is used.8L: More specifically, a controller mechanism is used which includes at least one 840 column wheel.

[0309] A ninth variant relates to a method and mechanism for step-by-step time setting of hour and minute displays. The invention proposes a solution for the time-setting function of the watch displays in two-minute increments following a reset to the reference position, in particular 12:00, as described in the seventh and eighth variants. It is controlled by the interface of a sympathetic clock, the data acquisition mechanism of which for time setting is as described in the sixth variant above.

[0310] The aim is, once again, to allow the execution of a cycle, for a first movement of an interface between the watch and the clock, a corrector for example, to perform the following functions in the watch at any time: bring the displays to a position corresponding to the current time, by a number of steps defined relative to the original position, for example 12:00; bring the displays to a position corresponding to the current time increased by an offset allowing waiting for a top seconds which releases the watch's resonator for precise time setting.

[0311] This description relates to a non-limiting construction of a mechanism that sets the time in two-minute increments. Increments of 1, 3, 4, 5, 6, and 10 minutes are also possible.

[0312] The watch includes: a corrector 932 coinciding with the interface of the clock or another element enabling the transmission of a back-and-forth movement; a rocker 931 having an arm 921 capable of driving the wheel by one tooth by back-and-forth movement; a jumper 904 maintaining the position of the minute display in the interval of the driving functions; a 30-tooth star carried by the minute display for steps of two minutes, in a manner analogous to the seventh variant; a clutch mechanism 906 between the display gear 905-907-908 and the finishing gear 910 which is in the open position for setting the time and can be closed in operation of the watch, in a manner analogous to the seventh or eighth variant.

[0313] In the specific embodiment illustrated in the figures, a 15-tooth 905 sprocket, which is also necessary, is advantageously used to replace the 30-tooth star. This option is not limiting, and the star must be defined according to the desired number of steps per minute. Ze = 60 min / 2 min. Therefore, the 15-tooth sprocket has 30 stable positions thanks to the double jumper 904 described in the figure 25 , and to the staggering of the two offset support surfaces 922 and 923 of the arm 921 of the rocker 931.

[0314] In the initial state, the first stable position therefore corresponds to the display obtained after returning to the reference position, i.e. 12:00 in this example.

[0315] The clutch is in the open position relative to the 910 finishing gear as seen in figure 24 The display is therefore independent of the watch's mechanism. This mechanism is also stopped by the stop lever during operation.

[0316] Regarding the time-setting function, the clock, according to the sixth variant, transmits via its interface a defined number of increments necessary to reach the current time, in two-minute steps. It also transmits one or two additional increments to allow for the waiting time until the second chime.

[0317] The clock interface collaborates with the watch corrector 932 which drives the rocker 931. This rocker 931 is constructed so as to drive the 30 star by one step, or, in the alternative embodiment, the 15 pinion by half a step.

[0318] The 931 rocker arm drives the 15-tooth pinion for 80% of its travel and returns to its rest position. The jumper then completes the remaining travel, with the remaining 20% ​​of the current travel, and positions the pinion for the next half-step, as shown in the diagram. figure 25 .

[0319] This execution fulfills the desired time-setting functions, allowing the clock to move the displays in two-minute increments up to the current time, and to add an offset.

[0320] In summary, the step-by-step process of setting the time on the hour and minute displays involves several steps described below. 9A: A reference position of the displays is defined. 9B: A watch 200 is used, comprising a corrector 932 cooperating with an interface of the clock 100 for the transmission of a back-and-forth movement, a rocker 931 capable of driving the minute display wheel 5 by one tooth per back-and-forth movement, and a jumper 904 maintaining the position of the minute display within the interval of the drive functions, the watch 200 also comprising a clutch mechanism 906 between a display gear 905, 907, 908 and a finishing gear 910.And, at any time, the clock 100 is able to bring the displays 4, 5, either to a position corresponding to the current time read on the clock 100 by driving the teeth of the minute display 5 by the rocker 931, by a number of steps defined relative to the reference position, or to another position corresponding to the current time increased by an offset allowing the waiting for a seconds signal enabling the stop mechanism 20 to release the resonator 10 of the watch 200 by the partial driving of the minute display 5 by the rocker 931 which only performs a part of the stroke corresponding to each tooth, the rest of the stroke of each tooth to complete the indexed rotation of the minute display 5 then being carried out under the impulse of the jumper 904. 9C: A predetermined step value for setting the time is determined.9D: The minute wheel or carriage of the 200 watch is precisely positioned by the combination of a star attached to the minute wheel or carriage, and a jumper with one or more teeth, the number of teeth of the star and the number of teeth of the jumper together defining the value of the predetermined pitch. 9E: More specifically, the minute wheel or carriage of the watch 200 is driven by the combination of, on the one hand, a star fixed to the minute wheel or carriage, and a rocker or a driver or a rake, the movement of which is controlled by the pendulum 100. 9F: More specifically, in a first phase, the pendulum 100 controls the stop mechanism 20 to stop the resonator 10, brings the displays 4, 5 into the reference position, and positions the clutch mechanism 906 in the open position relative to the finishing gear 910 which is then independent of the gear of the watch 200.9G: More specifically, in a second phase, the clock 100 transmits via its interface a defined number of movements necessary to reach the current time, in a predetermined integer number of steps. 9H: More specifically, in a second phase, the clock 100 transmits via its interface a defined number of movements necessary to reach the current time, in a predetermined integer number of steps, plus one or two movements corresponding to one or two additional predetermined steps to allow the waiting time until the seconds signal, enabling the stop mechanism 20 to release the resonator 10 of the watch 200. 9I: More specifically, a watch 200 is used whose rocker 931 is arranged to drive a thirty-tooth star wheel with one step, or a fifteen-tooth pinion with a half step.9J: More specifically, a watch 200 is used whose rocker 931 is arranged to drive a fifteen-tooth pinion by half a step, and drives the fifteen-tooth pinion through 80% of the stroke, and returns to its rest position, the jumper 904 ensuring the remaining 20% ​​of the current stroke, and positions the fifteen-tooth pinion for the next half step.9K: More specifically, a watch 200 is used which includes a constant-step time-setting mechanism, and includes a corrector 932 coinciding with the interface of the clock 100 or another element enabling the transmission of a back-and-forth motion, a rocker 931 capable of driving the wheel by one tooth per back-and-forth movement, a jumper 904 arranged to maintain the position of the minute display within the interval of the drive functions, a star carried by the minute display with a number of teeth according to the value of the required step, a clutch mechanism 906 between the display gear 905, 907, 908, and the finishing gear 910 and which is in the open position for time setting and can be closed during the operation of the watch 200, the interface of the clock 100 being arranged to cooperate with the corrector 932 of the watch 200 which drives the rocker 931 which is arranged to drive the star by one step, or half a step.9L: More specifically, a 200 watch is used, the star of which is formed by the minute track.

[0321] The seventh and eighth variants implement a function controller to ensure the execution of functions in the different phases:

[0322] In the seventh variant, the function controller has three positions: Start of function: it controls the disengagement of the finishing gear, stops the balance wheel, and releases the hammer; time-setting function: it cocks the hammer; end of function: it releases the clutch and the balance wheel.

[0323] In the eighth variant, the controller has two positions: Start of function: it controls the disengagement of the finishing gear, and stops the balance wheel; end of function: it releases the clutch and the balance wheel.

[0324] The invention proposes, without limitation, different embodiments, with either a specific controller integrated into the watch, similar to those used in chronographs, or a controller external to the watch, integrated into the clock.

[0325] For the watch's integrated controller, you can use: a rotary controller, of column wheel type, controlled by the interface (with two to five successive stable positions: 1-2-3-1-2-3-1 etc...); a shuttle-type reciprocating controller, controlled by the interface (two successive stable positions: 1-2-1-2-1 etc...).

[0326] When the controller is in the clock, the watch only has a back-and-forth cam controlled by the interface and returning to rest by default (a stable rest position, and one to three controlled positions: 1-2-3-2-1-2-3 etc...).

[0327] The column wheel configuration is well-suited to the seventh variant. For example, a three-position column wheel is chosen, with the positions selected sequentially by the clock via the user interface. This column wheel drives three levers, similar to those found in chronographs. These levers control the clutch, the stop lever, and the hammer(s), or are part of these mechanisms. The levers are designed to rest against the columns of the column wheel so that they can be activated as needed.

[0328] The different positions are: Position 0: Initial and final: clutch active, stop lever inactive, and hammer cocked; Position 1: Return to the reference position, in particular 12:00: clutch inactive, stop lever active, and hammer released; Position 2: Time setting: clutch inactive, stop lever active, and hammer cocked; Position 0: Return after complete rotation.

[0329] This execution can be applied to the eighth variant with a two-position column wheel.

[0330] The second execution with a simple shuttle is sufficient for the eighth variant where two positions are sufficient, and can replace the column wheel.

[0331] The design in which the controller is located within the clock is well suited to the seventh variant: the three-position column wheel described earlier is functionally replaced by a three-level snail cam, also located within the clock. This snail cam drives, via a sympathetic interface, a reciprocating cam within the clock. This cam controls the clutch, the stop lever, and the hammer(s), as required.

[0332] The different positions are: position 0: initial and final: clutch active, stop lever inactive, and hammer cocked; position 1: return to the reference position, in particular 12:00: clutch inactive, stop lever active, and hammer released; position 2: time setting: clutch inactive, stop lever active, and hammer cocked; position 0: return to zero of the cam.

[0333] This execution with a controller external to the watch is interesting because it prevents the watch from remaining in position 1 or position 2 when the watch is unexpectedly removed from the clock (during the execution of the function).

[0334] The construction is adapted to prevent the hammer from falling when moving from position 1 to position 0.

[0335] This execution in which the controller is in the pendulum can be applied to the eighth variant, with a snail and a two-position cam.

[0336] In summary, such a controller responds to the desired time-setting functions, allows the disengagement of the finishing gear display and its engagement, allows the hammer to be controlled if needed, and allows the stop lever to be controlled.

[0337] Naturally, the use of such a controller is also applicable to the other variants described above.

[0338] Thus, these different variants allow us to fulfill the following functions: start the watch when it is stopped and placed on the clock; ensure a minimum autonomy of twelve hours when the watch is removed from the clock to be worn; keep the watch running when it is on the clock; set the time when the watch is placed on the clock or on demand, with an accuracy of ±15s; keep the watch on time as long as it is on the clock; in a variant, the sympathetic set 1000 includes an option with a disengagement mechanism, so that the function can be deactivated for storage of the stopped watch on the clock.

[0339] More specifically, the first interface includes a first external actuator in the clock, and a first internal actuator in the watch.

[0340] Similarly, the second interface includes a second external actuator in the clock, and a second internal actuator in the watch.

[0341] Similarly, the third interface includes a third external actuator in the clock, and a third internal actuator in the watch.

[0342] Similarly, if we generalize to a larger number of interfaces, the nth interface has an nth external actuator in the pendulum, and an nth internal actuator in the watch.

[0343] The whole thing, and the different processes corresponding to as many different use scenarios described above, are based on clocks and watches without chimes.

[0344] It is understood that it is possible to create such a nice set with a chiming clock, and / or a chiming watch.

[0345] The chiming mechanisms have the advantage of providing precise references for setting the time, which one can imagine using for setting the time on sympathetic watches.

[0346] However, precautions must be taken.

[0347] The striking snails can be used for the time-setting mechanism. In an example of time setting in five-minute increments, the corresponding snail must have 144 five-minute increments and will not be used for the striking mechanism. In a striking mechanism, the hour snail is generally linked to the striking mechanism, so even the drive is unique. The watch can be striking, but this makes the system slightly more complex because the striking mechanisms must be isolated during sympathetic operation, where the sympathetic clock 100 and the sympathetic watch 200 cooperate. Otherwise, the striking mechanisms would sound continuously during time setting and could cause the mechanism to jam.

[0348] Under this condition of interposing insulators, which makes the execution more complex, the realization of such a mechanism for a striking watch is possible; the striking snails of the watch would then be driven by the sympathetic time setting.

[0349] Only the basic winding and time-setting functions have been described here; the transfer of other information concerning other quantities is of course possible by extrapolation: second time zone, day-night display, AM / PM, date, and more generally calendar elements, or others.
