Description

[0001] The invention relates to a timepiece mechanism for indicating and storing time information and a mechanism for correcting a device for displaying time information. The invention also relates to a timepiece movement comprising such a mechanism. The invention also relates to a timepiece, in particular a watch, comprising such a movement or such a mechanism.

[0002] Document EP1475681 discloses a device that allows the display of fractions of a second of a chronograph only when the chronograph is stopped. This system implements a cam secured to a pinion rotating at the rate of one revolution per second. The time information is displayed by means of a rack which is engaged with the display member, and which is likely to be in contact with the cam. When the chronograph is stopped, the feeler of the rack is in contact with the flank of the cam and is thus positioned so as to display the time information. When the chronograph is started or when resetting to zero, the feeler of the rack is raised to a predetermined position by an arm or a column wheel so that it is free of the cam's travel.

[0003] Document CH700902 concerns a switching mechanism capable of displaying time information on demand. This system has the particularity of displaying day / night information only in timepiece setting mode. This implements the characteristic elements of the conventional retrograde display device. In normal operation, when the crown is in the pushed position, the end of the stem controls the angular position of the feeler so that its beak is not in contact with the flank of a cam making a complete revolution in 24 hours. In the time-setting position, the stem releases the feeler, which is pressed against the cam under the effect of a return spring.

[0004] Document EP2159652 relates to a time display mechanism for displaying or not the current time. Under the actuation of a control lever, the set of hands indicates the time in a conventional manner or it is arranged in a predetermined position. This device implements spiral cams which are respectively engaged with the hour and minute kinematic chain. The time information is displayed by means of racks respectively engaged with the hour and minute hands. In the non-time display position, the racks, under the actuation of the control lever, are positioned so that their feelers are outside the cam travel. Consequently, the set of hands is arranged in a predetermined position.

[0005] Application EP1918792A1 relates to a disengagement device added to the conventional retrograde display device which, during the adjustment phase of the timepiece, makes it possible to move the feeler of the retrograde display lever away from the path of the spiral cam via a return lever. This return lever carries a toothed portion designed to act directly on the pinion which carries the retrograde time information, under the actuation of a control cam itself controlled by the stem. This solution thus requires a significant number of components which are added to the retrograde mechanism. Furthermore, immobilization of the retrograde display lever, during a possible retrograde information storage phase, causes immobilization of the return lever. Thus, in this configuration, it is not possible to act on this return lever. It is therefore not possible to act on the timepiece adjustment device due to the risk of breakage.

[0006] Application EP0851321A2 relates to a multifunction watch which is equipped in particular with a rapid time correction mechanism. The latter is kinematically linked to a retrograde display device for indicating the days of the week. When the stem actuating this correction device is pulled, the feeler of the retrograde lever is raised under the effect of the translation of a return lever which is movable in translation by the rotation of the pull-piece. Thus, when the stem is manipulated in the rapid hour correction position, the feeler of the retrograde lever is released from the path of the spiral cam and the retrograde day indicator hand is arranged in a predetermined position. Furthermore, it appears that immobilizing the retrograde display lever, during a possible phase of memorizing the retrograde information, blocks the translation of the return lever.So in this configuration the rod cannot be pulled and the correction position reached.

[0007] In view of the state of the art, it appears that there is no switching mechanism capable of selectively indicating current information or stored information by the same display member. It is indeed noted that the known switching mechanisms only allow selectively indicating current information or predetermined information that cannot be adjusted. To do this, a device connected to the display device makes it possible to control a lever of the display device mounted on the frame of a timepiece in a predetermined position.

[0008] In view of the prior art, it appears that there is also no correction mechanism for a retrograde device that is operable at all times.

[0009] The aim of the invention is to provide a timepiece mechanism for indicating and storing time information and a correction mechanism for a device for displaying time information. In particular, the invention proposes a timepiece mechanism for indicating and storing time information which makes it possible to selectively indicate current information and stored information by the same display member and a correction mechanism for a device for displaying time information which allows correction at any time of a timepiece, in particular a timepiece indicating stored time information.

[0014] The attached drawings represent, by way of examples, embodiments of clock mechanisms according to the invention.

[0015] THE figures 1 to 3 are schematic views of an embodiment of a timepiece according to a first aspect of the invention.

[0016] THE Figures 4 and 5 are schematic views of an embodiment of a mechanism according to the first aspect of the invention.

[0019] THE figures 14 to 17 are schematic views of an embodiment of a timepiece according to a second aspect of the invention.

[0020] THE figures 18 to 22 are schematic views of an embodiment of a mechanism according to the second aspect of the invention.

[0021] A first embodiment of a timepiece 1 according to the first aspect of the invention is described below with reference to figures 1 to 13 . The timepiece is for example a watch, in particular a wristwatch. It comprises a movement 2. This movement itself comprises a mechanism 3 for indicating and storing time information, one embodiment of which is described below.

[0022] As will be described below, the timepiece, in particular the movement and more particularly the mechanism, has the specific feature of selectively indicating current time information and stored time information, in particular stored information of the current time information, by the same display member. The control is carried out by the actuation of a single control member 4. Such an indication and storage mechanism 3 may for example be useful for marking a time, time information, or any information derived from the time on demand by a conventional display member normally provided for displaying the current information in question.

[0023] In the described embodiment, the stored information is represented or indicated by a retrograde system. Thus, the figure 1illustrates an embodiment in which a retrograde seconds memorization hand S' is added to the conventional second hand S of the timepiece. The movement of the display organ S' constituted here by a memorization hand can therefore be retrograde.

[0024] In normal operation, as shown in the figure 1 , the hand S', like the second hand S, indicates the current second. A first action, in particular pressure on the control member 4 as shown in figure 2, causes the hand S' to stop without acting on the second hand S, which continues its movement. In this state, the timepiece then provides a simultaneous indication or display of the current time information and the stored time information. A second action, in particular pressure on this same control member, repositions the hand S' so that it again displays the current second, as illustrated in figure 3 . The two hands S and S' are thus synchronized again. Each hand therefore displays the current second.

[0025] The mechanism 3 for indicating and storing time information comprises a transmission device 7 linking a counting chain 5 or counting system capable of providing the time information and a member S' for displaying the time information arranged so as to selectively display the current time information and the stored time information. The transmission device comprises: a cam C; a lever device L including a lever L1, a feeler L2 and a first elastic element R returning the lever and the feeler to a determined relative position.

[0026] The lever L1 is kinematically linked to the display member S' of the time information and the sensor L2 is returned by a second elastic element RL against the cam C.

[0027] In this embodiment, the time information concerns seconds. It can just as well concern hours, minutes, or even another unit of time magnitude.

[0028] The display member may comprise or consist of a needle cooperating with a marking bearing indications and / or graduations. By "counting chain" or "counting system" is meant any device for driving at least the display member. The display member is preferably not part of the counting chain. For example, a counting chain comprises an accumulator such as a barrel, a gear train in particular regulated by a balance-spring system and escapement.

[0029] By "selectively displaying the current time information and the stored time information" is meant that at any time, outside of transient phases, the display member indicates either the current time information or the stored time information. The transient phases are instantaneous or quasi-instantaneous. They last only a few fractions of a second, for example less than 0.3 seconds. The display member therefore never comes to a predefined position independent of time. It follows that the display member permanently performs a function of displaying time information.

[0030] The lever device L is preferably pivoted on a frame 6 of the mechanism, in particular a frame of the movement or of the timepiece.

[0031] As shown in the figure 4, the cam C is for example a spiral cam. It can be directly carried by a seconds wheel MS in kinematic connection with a second organ S for displaying the time information. In particular, the second display organ S can be driven onto the seconds wheel. The shape of the cam C is for example such that the first display organ S' performs a retrograde stroke with instantaneous return. The second display organ S may or may not be retrograde.

[0032] The lever device L is pivoted about an axis P. As seen previously, the lever device comprises two parts: the lever L1 and the feeler L2. Each of these parts is pivoted about the axis P. The two parts are connected to each other by a first elastic element such as a return spring R. This first return element makes it possible to return the lever and the feeler to a determined relative position as illustrated in figure 4 .

[0033] The lever L1 carries a toothing L10 or rake, for example at one of its ends. This toothing is engaged with a pinion PS' to which the display member S' is kinematically linked. In particular, a seconds memorization hand S' can be driven onto the pinion PS'. The second part of the lever device comprises a feeler L2 including a feeler head L20 which bears against the profile of the cam C under the effect of a second elastic return element RL.

[0034] In normal operation, namely when the display members S and S' are synchronized, the lever device behaves like a rigid element. It can therefore be likened to a rigid component pivoted about the axis P. Indeed, the first elastic element R contributes to maintaining the lever and the probe in a predetermined position relative to each other. This predetermined position is defined by stops provided on the lever and the probe and cooperating with each other by obstacle in the predetermined position. For example, a pin GL2 is driven into the probe L2 and is arranged to abut against a flank FL1 of the lever L1 as shown in the Figures 4 and 5 .

[0035] Alternatively, the pin could be driven into lever L1 and cooperate with a flank of lever L2 or another element of the feeler.

[0036] Thus, a rotation of the cam C in the anti-trigonometric direction induces a rotation of the lever device L in the trigonometric direction so that the toothing L10 can drive the display member S' in synchronization with the second display member as shown in the figures 6 to 9 . By "synchronization" here is meant that the two display elements indicate the same time value. However, their movements may not be identical. In particular, their angular displacement speed values ​​may be different.

[0037] Advantageously, the mechanism 3 comprises a blocker LB of the lever L1. The blocker can be actuated by the control member O, in particular the pusher 4, to selectively position the blocker in a first position leaving the lever L1 free or in a second position blocking or immobilizing the lever L1.

[0038] To do this, the control member O can actuate the blocker LB via a memory control element RC, such as a cam, in particular a column wheel.

[0039] The blocker can act on one end L100 of the lever L1 and / or can act by friction on the lever L1.

[0040] When the display members S and S' are synchronized, the blocking lever or blocker LB is positioned so that it cannot act on the lever L1 as shown in the figure. figure 10 .

[0041] This LB blocker is for example controlled by a memory control element such as a cam which is for example in the form of a column wheel RC which is angularly indexed by a jumper spring RS. This can be provided with a binary profile RCa which is made up of columns and hollows. In the aforementioned configuration shown in the figure 10, one end LB1 of the blocker LB is supported against one of the columns of the cam RC so that an arm LB10 of the blocker LB is located out of reach of the end L100 of the lever L1.

[0042] The column wheel RC is also provided with a ratchet toothing RCb which is intended to be actuated and driven by an angular pitch by a control lever LC under the effect of the control member O, in particular the pusher 4. Pressure on the latter induces rotation of the column wheel RC so that the end LB1 of the blocker LB moves within a hollow of the column wheel under the effect of a return spring RLB. In this configuration shown in the figure 11, the arm LB10 of the blocker LB exerts a force F against the oriented end L100, in particular as a function of the coefficient of friction f at the interface of the arm LB10 and the end of the lever L1, such that the lever L1 is immobilized or blocked in rotation around the axis P. However, the feeler L2 can for its part rotate around the axis P under the effect of the rotation of the cam C. This rotation is done against the first elastic element R which deforms. This situation results in an immobilization of the display member S', while the second display member S continues its travel.

[0043] Pressing the control O again repositions the column wheel RC in a configuration similar to that of the figure 10. The arm LB10 of the blocker LB then moves away from the end L100 of the lever L1 against the effect of the spring RLB. The lever L1 is therefore released and, under the effect of the first elastic element R, then repositions itself so that its flank FL1 comes into abutment against the pin GL2 of the probe L2. The lever device L thus resumes its configuration as illustrated in the figures 8 to 10 . Thus, the display organs S and S' are synchronized again.

[0044] In the memorization phase, that is to say when the display unit S' indicates the memorized time information, as shown in figure 11 , the driving organ of the movement of the timepiece, through the cam C, opposes the torque produced by the first elastic element R, this torque being added to that produced by the second elastic element RL. This situation is not optimal with regard to the chronometry of the timepiece.

[0045] To overcome this problem, the mechanism 3 may comprise an isolating device LI arranged so as to have a first position in which the feeler L2 is kinematically linked to the time information counting chain and a second position in which the feeler L2 is disconnected from the time information counting chain. Thus, in the first position, the feeler L2 is supported against the cam C and, in a second position, the feeler L2 is disconnected from the cam C or kept at a distance from the cam C.

[0046] Advantageously, the isolation device is arranged so as to act on one end L200 of the probe L2, in particular to act by contact.

[0047] Preferably, the isolation device and the blocker are kinematically linked, or even integral or fixed to each other. Thus, the isolation device can be in a first position when the blocker is in its first position and the isolation device is in a second position when the blocker is in its second position.

[0048] Preferably, an isolating device LI is therefore added to the blocker LB so as to release the feeler L2 from the path of the cam C when the blocker LB immobilizes the lever L1. To do this, the isolating device LI works in synchronization with the blocker LB by means of the column wheel RC. figures 12 And 13 illustrate such an isolation device.

[0049] When the display organs S and S' are synchronized as shown in the figure 12, the isolation device LI, comprising an isolation lever LI1 and an elastic element RLI such as a spring, is positioned so that it cannot act on the feeler of the lever device L, just like the blocker LB. More particularly, an end LI10 of the isolation device LI is located in a hollow of the profile RCa of the cam RC under the effect of a spring RLI so that a flank LI100 of the isolation device LI is located out of range of the flank L200 of the feeler L2.

[0050] In the memorization phase, as shown in the figure 13 , the side LI100 of the isolation device LI presses against the side L200 of the probe L2 against the springs R and RL, while the end L100 of the lever L1 is previously immobilized by the arm LB10 of the blocker LB. Thus, in all situations, in particular those represented on the figures 12 And 13, the driving organ of the movement of the timepiece, via the cam C, opposes as much as possible the torque produced by the spring RL. This maximum opposition is encountered in the situation of synchronization of the display organs.

[0051] Of course, several storage devices can be associated so as to store more than one piece of time information, in particular information that is kinematically linked to each other, for example the indications of minutes and seconds, hours and minutes, or even hours, minutes and seconds. Advantageously, these devices can be controlled by a single control member via a single RC cam intended to synchronizingly control the levers of each of these pieces of time information. It is thus possible to obtain a mechanism, a movement or a timepiece making it possible to store: hours and minutes, or minutes and seconds, or hours, minutes and seconds.

[0052] Advantageously, the isolating device is linked to the control member O, in particular to a push button 4, the control member itself being linked to the blocker LB. Thus, the control member makes it possible to simultaneously control the change of position of the blocker and the isolating device.

[0053] Also, the control member may comprise an element for actuating the isolation device via a storage control element RC, in particular the column wheel, which actuates the blocker LB.

[0054] A second embodiment of a timepiece 1' according to the second aspect of the invention is described below with reference to figures 14 to 22. The timepiece is for example a watch, in particular a wristwatch. It comprises a 2' movement. This movement itself comprises a 3' mechanism for correcting a device for displaying time information as described below.

[0055] The correction mechanism allows bidirectional correction for a device for displaying time or time-derived information or bidirectional correction of a device for displaying time or time-derived information. Such a mechanism is particularly suitable for correcting in both directions of correction a time or time-derived indication which is capable of being stored by a display and storage device according to the first aspect of the invention.

[0056] In the embodiment described, the information to be corrected is indicated retrogradely, in particular retrogradely with instantaneous return. By "retrograde display", we mean any display capable of implementing a display member capable of pivoting in two directions of rotation. Instead of making a complete turn, the display member travels from a starting point A to an arrival point B in front of a graduation representing, for example, a time-related quantity. Once the journey from A to B has been completed, the indicating member can in particular return back to point A instantaneously. In the following, the display members M and M' are minute display members. However, they could just as well be hour or second display members, or even another quantity. As in the previous embodiment, the display members can comprise or consist of hands.

[0057] Elements of the embodiment according to the second aspect of the invention and elements of the embodiment according to the first aspect of the invention which are identical or which have the same function bear the same references.

[0058] As in the first embodiment, a spiral-shaped cam allows the information to be displayed and ensures the instantaneous return of the display member M' to a predetermined position by means of the lever device L and the return spring RL. This cam is kinematically linked to the current time display system, so that it is rotated during a forward and backward correction of this current display. However, the geometry of this cam, characterized by the presence of a steep flank to allow the instantaneous return of the lever device and therefore of the display member M', poses a problem during a backward correction. Indeed, a correction in the anti-clockwise direction is not possible when the feeler of the lever device reaches the level of the steep flank of the cam. This configuration therefore induces a blockage which risks leading to the deterioration or even breakage of elements.

[0059] Also, the 3' mechanism, like the variants of the 3 mechanism represented on the figures 12 And 13 , includes a clutch system connected to the retrograde system which allows the feeler to be disconnected from the cam. In the mechanism 3', this system also allows bidirectional rotation of the cam during the operation of adjusting the time information. This clutch system has the specific feature of acting directly on the retrograde lever device L, in particular by a rotational movement of the isolating device. Indeed, such a configuration allows the functions of correction and storage of the time information to interact advantageously. Another advantage lies in the fact that it minimizes the number of components required when it comes to multiplying the correction mechanisms.

[0060] In the solutions of the prior art, it appears that immobilizing the lever determining the display of time information, during a possible phase of memorizing the time information, blocks the movement of the return lever allowing said lever to be released. Thus, in this configuration, the rod cannot be pulled and the correction position reached.

[0061] The embodiments of correction mechanisms according to the second aspect of the invention make it possible to remedy the aforementioned defects. Indeed, they can be activated at any time, that is to say even when time information is stored.

[0062] As shown in the figure 18, the mechanism 3' for correcting a device for displaying time information, comprises a first member M for displaying first time information and a second member M' for displaying the first stored information. The mechanism comprises a device for isolating the first and second display members.

[0063] Thanks to the presence of the isolation lever, it is possible to operate the mechanism as shown below. In normal operation as shown in the figure 14 , the second display organ M', just like the first display organ M, indicates for example the current minute. In the correction phase as shown in figure 15, namely when an adjustment crown CR is pulled out, the second display member M' is positioned in a predetermined position while a bidirectional rotation of the adjustment crown causes the first display member M to be driven in both directions. The predetermined position is preferably time-invariant.

[0064] In the memorization phase as shown in the figure 16 , under the actuation of the control member O, the second display member is stopped while the first display member continues its travel. In this configuration as shown in the figure 17 , the adjustment crown CR has no effect on the second display member M' which remains in its position as defined by the control member O. A bidirectional rotation of the adjustment crown CR then causes the first display member M to be driven in both directions of rotation.

[0065] Thus, the isolation device has a first configuration in which the positions of the first and second members are linked and a second configuration in which the positions of the first and second members are independent.

[0066] The mechanism 3' may comprise, as in the first embodiment, a spiral cam C directly carried by a cannon pinion CH on which the first display member is fixed, in particular driven. The second display member M' is moved by a retrograde system similar to that described in the first embodiment.

[0067] The isolating device can be shaped so that it can be actuated by a pull rod T of the correction mechanism and by a cam RC of the memory mechanism.

[0068] In normal operation as shown in the figure 18, namely when the first and second display members are linked or synchronized, the isolation device is in the first configuration. More particularly, the isolation device is shaped or arranged so as to be out of range of the retrograde lever device L. More particularly, an end LI10 of the isolation device LI is located in a hollow of the binary profile RCa of the cam RC under the effect of a spring RLI so that a flank LI100 of the isolation device LI is located out of range of a flank L200 of the feeler L2.

[0069] The isolation device LI can be actuated by a correction element, in particular a rod TR or a pull rod T, to selectively position the probe L2 in a first position defined by the first configuration of the isolation device LI and in a second position defined by the second configuration of the isolation device.

[0070] Actuation of the isolation device LI by the correction element can induce rotation of the lever device L10.

[0071] As seen previously, the isolating device and the correction element can be arranged so that the actuation of the isolating device LI by the correction element induces the positioning of the second display member M' in a predefined position, in particular in an extreme or stop position. This position can indicate to the user the correction state. In the memorization phase, the display can also be corrected. In this case, the second member M' remains in the position which is memorized. These functions are ensured by a particular arrangement of the isolating device LI, the correction element T, TR, the memorization control element RC and the blocker LB. In each of the two cases, the isolating device is in the second configuration. In addition to the arrangement shown in the figures 18 to 22 , other arrangements are obviously possible.

[0072] Furthermore, the control member O and the isolating device LI are advantageously arranged such that the control member can actuate the isolating device. In particular, this actuation is carried out via the storage control element RC.

[0073] Thus, the isolation device is in the first configuration, unless the control member or the correction element is in a state conditioning the second configuration of the isolation device. The preceding "or" is an "inclusive or", that is to say that it is sufficient that at least one of the control member and the correction element is in a state conditioning the second configuration of the isolation device, for the isolation device to be in this second configuration. If each of the control member and the correction element is in a state conditioning the second configuration of the isolation device, the isolation device is in a fortiori in this second configuration.

[0074] The pull rod T of the correction mechanism has a completely conventional operating mode. It is engaged with the rod TR by means of a pull rod stud PT so that it is driven in rotation when the rod is actuated in translation. The positions of the rod: 1.- neutral position, 2.- adjustment position, are also conventionally defined by the notching produced by a beak of a jumper (not shown in the figures) intended to cooperate with the pull tab.

[0075] In the configuration of the figure 18, a flank LI1000 of the isolating device is located opposite a pin GT1 of the pull rod T. Thus, a pull of the adjustment rod TR induces the pivoting of the isolating device by means of the pin GT1 which presses on the flank LI1000 of the isolating device. In the adjustment phase, the flank LI100 of the isolating device LI thus actuates the flank L200 of the lever device L, which positions the lever device L against the return spring RL in a determined angular position so as to release the feeler L20 from the path of the cam C. A bidirectional rotation of the cam C is thus authorized. The kinematic chain CM intended to correct the display indicated by the first display member M can therefore be driven in both directions of rotation as shown in the figure 19 .

[0076] The CM kinematic chain can be activated by the effect of a GT2 pin of the pull rod T. In the adjustment position, this chain positions a rocker B against a spring RB so as to engage the CM kinematic chain via the front teeth DF of a sliding pinion PC as shown in the figure. figure 20 .

[0077] In the memorization phase as shown in the figure 21, namely when the second display member M' is immobilized under the effect of a blocking lever or blocker LB, the isolating device LI is arranged to disengage the feeler L20 from the path of the cam C under the effect of the control cam RC. More particularly, the end LI10 of the isolating device LI bears against one of the columns of the cam RC so that the flank LI100 lifts the flank L200 of the lever L2 against the actions of the springs R and RL. In this configuration, the pin GT1 of the pull rod T is out of reach of the flank LI1000 of the isolating device LI. Thus, pulling the adjustment rod TR has no effect on the isolating device LI which is previously positioned such that the feeler L20 is disengaged from the path of the cam C. Bidirectional rotation of the cam C is thus permitted.The CM drive train intended to correct the display indicated by the first display member M can therefore be driven in both directions of rotation as shown in the . figure 22 .

[0078] Thus, preferably, in the first position of the isolation device LI, the feeler L2 is arranged so as to bear against the cam C linked to the first display member M under the effect of the second elastic element. In a second position of the isolation device LI, the feeler L2 can be arranged so as to be disconnected from the cam C, or kept at a distance from the cam.

[0079] The isolating device LI may comprise the isolating lever LI1 capable of acting or arranged to act on the pivoted lever device L and including the lever L1, the feeler L2 and the first elastic element R recalling the lever L1 and the feeler L2 in a determined relative position. The lever L1 is kinematically linked to the second display member M'.

[0080] The isolating device, the correction element and the probe are arranged so that the probe is positioned in the second position by the correction element TR, T when the blocker LB is in a first position leaving the lever L1 free.

[0081] The blocker LB can cooperate with the storage control element RC to selectively position the blocker in a first position leaving the lever L1 free or in a second position blocking the lever L1.

[0082] The isolation device LI can be arranged to act on one end L200 of the probe L2 and / or to act by obstacle on the probe.

[0083] In other words, according to the second aspect of the invention, the isolation device preferably comprises: a first element intended to link it kinematically to the correction element, in particular by contact cooperation, a second element intended to link it kinematically to the storage control element, in particular by contact cooperation, a third element intended to link it kinematically to the probe, in particular by contact cooperation.

[0084] The configuration, in particular the position, of the correction element and the configuration, in particular the position, of the storage control element determine the configuration, in particular the position, of the isolation device. The configuration, in particular the position, of the isolation device, and the configuration, in particular the position, of the storage control element determine the configuration, in particular the position, of the probe.

[0085] Of course, several correction devices can be associated so as to correct more than one time information, in particular information which is kinematically linked to each other, for example the hour and minute indications. Advantageously, these devices can be controlled by a single pull rod T and a single control cam RC so as to synchronously control isolation levers specific to each of the display members of the stored time information. Preferably, the isolation levers LI and the pull rod T can form a single kinematic chain.

[0086] In the various embodiments, the blocker could be actuated directly by a control element such as a push button, without using a column wheel. In this case, the stored information can be displayed only when the user acts on the control element.

[0087] In the various embodiments, the blocker LB can be arranged so that it can block the lever L1 regardless of the position of the lever L1 in the “memorization” phase. In other words, in the “memorization” phase, the blocker LB can be arranged so that it can stop the display member S' regardless of the position of the display member S'.

[0088] In the various embodiments, the lever device L may be manufactured in one piece or be a single piece. In this case, the first elastic element R is produced by an elastically deformable part, in particular an elastically deformable part separating the lever L1 and the feeler L2.

[0089] In the various embodiments, "storing time information" means an action of storing time information. This storage action is triggered by a user action. This storage action relates to storing the current or instantaneous time information during the user action. Thus, with each specific user action, new time information can be stored. The display of this stored time information can be maintained. Storing time information consists of freezing the current or instantaneous time information. Other components can continue to display the current time information when some are frozen or blocked to indicate the stored time information.

[0090] In the various embodiments, the first elastic element and the second elastic element are distinct.

[0091] In the different embodiments, the probe L2 can be articulated or pivoted on the lever L1.

[0092] Positioning display members in one or more random or once-and-for-all positions, i.e. in one or more positions that cannot be defined or modified by the user, as can be found in on-demand display mechanisms, does not constitute memorization within the meaning of the invention.

[0093] The first and second aspects of the invention can obviously, except in the case of technical or logical incompatibility, be combined.
