Description

[0001] Device for selecting and actuating at least two functions of a clockwork movement

[0002] The present invention relates to a device for selecting and actuating at least two functions of a watch movement. In particular, the present invention relates to a device for correcting at least two displays of a watch movement.

[0003] Such correction devices are used in complication watches in order to be able to correct the information displayed by these different complications. The complications to be corrected in connection with the present invention relate more particularly to “astronomical” complications, such as the indication of the date, the day of the week, the month, or the moon phase.

[0004] Traditionally, a watch is equipped with a winding stem, which can occupy a first, neutral position for winding, a second, pulled-out position for correcting the date, for example, and a third, pulled-out position for setting the time. A single complication can therefore generally be corrected using the winding stem, which therefore allows three functions of the watch to be acted upon (winding, correcting the date, and setting the time, for example).

[0005] In order to correct other complications, different pushers must be provided and distributed around the circumference of the watch case, the number of pushers being adapted to the number of complications to be corrected. These different pushers present on the watch case, imposed by the number of complications, can be considered unaesthetic. In addition, these pushers or correctors make the construction of the watch case more complex: it is necessary to take into account certain elements such as the horns which can sometimes require the addition of intermediate mobiles in the correction mechanism to move the pusher or corrector. Finally, these multiple pushers or correctors cause as many openings in the case which increases the risks of water resistance problems.

[0006] To solve this problem, for example, patent EP 2 701 015 has proposed a device for correcting a plurality of time functions displayed by a timepiece. This correction device comprises a push-piece for selecting the complication to be corrected, the actuation of which rotates a selection wheel carrying a corrector wheel in order to bring said corrector wheel into engagement with a corrector pinion of the selected complication to be corrected, said corrector wheel being furthermore rotated by the winding stem, in one of its two pulled-out positions, by means of a suitable gear train, to in turn rotate said corrector pinion in order to correct said complication.

[0007] Such a device makes it possible to eliminate all correction pushers, keeping only one pusher to select the complication to be corrected and the winding stem to carry out the correction.

[0008] However, this device is not suitable if one wishes to eliminate the use of any pusher, and to be able to select the complication to be corrected and correct said complication solely by rotating movements of two control members.

[0009] This device is also not suitable if one wishes to eliminate the use of any pusher, and keep only a single control stem, such as the winding stem, to both select the complication to be corrected and correct said complication.

[0010] Document EP 3 882 718 also describes a device for correcting a number N of complications of a timepiece comprising a mechanism for selecting the complication to be corrected arranged to be actuated by the winding stem. Said winding stem can conventionally occupy a pushed position for winding, a first pulled position for setting the time and a second pulled position for selection / correction. In its selection / correction position, the winding stem actuated in one direction of rotation makes it possible to select the complication to be corrected and actuated in the other direction of rotation makes it possible to correct the selected complication to be corrected.The correction device further comprises a correction gear arranged to be actuated by the winding stem to correct the selected complication to be corrected, N complication correction mechanisms arranged to be capable of cooperating with the correction gear to correct their respective complication and a selection mechanism comprising a selection wheel mounted so as to be able to rotate on said frame, and cooperating with the winding stem in its correction / selection position to drive it in rotation.An activation member of the correction mechanism of the selected complication to be corrected is arranged to be moved with the selection wheel so as to cooperate with the correction mechanism of the selected complication to be corrected in order to move it from a passive position, in which said correction mechanism does not cooperate with the selection wheel or with the corrector gear train or with its respective complication, to an active position in which said correction mechanism of the selected complication to be corrected can cooperate with the corrector gear train to be actuated when said corrector gear train is activated by the winding stem pivoted in the correction direction in its selection / correction position, in order to cooperate with said selected complication to be corrected to carry out its correction.

[0011] Such a device certainly makes it possible to eliminate all correction pushers and to select and correct two or more complications solely by means of the winding stem. However, this device is complex and includes a large number of components, some of which, such as the selection wheel, are bulky.

[0012] Additionally, with both of the above solutions, it is necessary to provide a display of the selection. Without a display, the user would have to remember the last selection made or try to make a correction without knowing which one to make and then select the correct correction.

[0013] The aim of the present invention is to provide a device for selecting and actuating at least two functions of a watch movement which is simple, compact and which allows the selection and actuation of several functions, in particular functions for correcting at least one complication or display, using a single control member which is preferably the winding stem. The invention also aims to propose a selection and actuation device which makes it possible to avoid having to display the current selection, while remaining simple and quick for the user who is not forced to remember what the last selection made was.

[0014] The present invention relates to a device for selecting and actuating at least two functions of a watch movement according to claim 1, a watch movement comprising such a device and a timepiece comprising such a movement.

[0015] The attached figures illustrate schematically and by way of example an embodiment of a device for selecting and actuating at least two functions of a watch movement according to the invention.

[0016] Figure 1 illustrates an embodiment of a selection and actuation device according to the invention in a position in which a first correction mechanism is selected, the winding stem being in its first pushed position.

[0017] Figure 2 illustrates the device of Figure 1 in which the first correction mechanism is always selected and the winding stem in its pushed position is pivoted in a first direction by more than one revolution.

[0018] Figure 3 illustrates the actuation of the first selected correction mechanism, the winding stem being in its first pulled-out position. Figure 4 illustrates the device in a position in which a second correction mechanism is selected, the winding stem being in its first pushed-in position.

[0019] Figure 5 illustrates the actuation of the second selected correction mechanism with the winding stem in its first pulled-out position.

[0020] Figure 6 illustrates the device in a time-setting position, with the winding stem in its second pulled-out position.

[0021] Figure 7 illustrates in detail the selection mobile of the selection and actuation device of Figures 1 to 6, in particular in the configuration of Figures 1, 3 and 6.

[0022] The selection and actuation device according to the invention is intended to equip a watch movement to enable at least two functions of the watch movement to be selected and actuated. The functions to be selected and actuated may be functions for correcting one or more complications or one or more displays, a winding function for a driving member such as a barrel or an adjustment function such as setting the time of a time display.

[0023] According to the invention, a single control member which can move in rotation and translation makes it possible to select and activate the functions.

[0024] Preferably, and as in the embodiment illustrated in the figures, the control member is a winding stem 1. In addition to winding and setting the time, the selection and actuation device according to the illustrated embodiment makes it possible to select correction functions and to actuate a first and a second correction mechanism 91, 92 represented by their first wheel set in the figures.

[0025] The winding stem 1 is arranged in a conventional manner to occupy three successive distinct axial positions: a pushed position for winding, a first pulled position for actuating the correction functions and a second pulled position for setting the time. The winding stem 1 carries in a known manner a winding pinion 2 mounted freely in rotation and a sliding pinion 11 adjusted squarely on the winding stem 1.

[0026] The winding pinion 2 meshes with a crown wheel 20 kinematically connected in a known manner to the driving member of the movement (for example, in the case of a barrel, via the ratchet fixed squarely on the barrel arbor).

[0027] A pull rod 12 is pivotally mounted at A and is arranged to switch between three distinct positions when the winding stem 1 is pulled or pushed in a conventional manner by means of its tenon which is housed in a hollow in the winding stem 1. The pull rod 12 comprises a first arm 121 carrying a pin 120 arranged to cooperate with the active end 130 of a pull rod spring 13. The pull rod spring 13 is arranged to determine the three distinct positions of the pull rod 12 and consequently the three successive distinct axial positions of the winding stem 1.

[0028] The puller 12 further comprises a beak 123 arranged to cooperate with a control lever 14 of the sliding pinion 11 pivoted on the movement and subjected to the action of a return spring 15. The control lever 14 cooperates with the sliding pinion 11 via a beak 141 housed in a hollow of said sliding pinion 11 to slide the latter on the winding stem 1 when the control lever 14 pivots.

[0029] When the winding stem 1 is in its pushed position or winding position as illustrated in figures 1, 2 and 4, the pull 12 is in its winding position pushed by the pull spring 13 against a stop of the clockwork movement and the control lever 14 of the sliding pinion 11 holds the latter in a position on the winding stem 1 in which said sliding pinion 11 meshes with the winding pinion 2. Thus, by turning the winding stem 1 (for example by means of a crown not shown), the sliding pinion 11 drives the winding pinion 2 which itself drives the crown wheel 20 for winding the driving member of the movement. The winding function is therefore carried out conventionally. The puller 12 also comprises a second arm 122 arranged to cooperate with a time-setting lever 3 pivoted on the movement and subjected to the action of its return spring 31.The time-setting lever 3 carries a pin 32 arranged to pass through an opening 41 of a correction lever 4. The correction lever 4 is pivoted on the movement and carries a main gear 5. Depending on the position of the correction lever 4 and the pin 32 of the time-setting lever 3 in the opening 41, the main gear 5 meshes either with a time-setting gear 33 kinematically connected to the minute train for setting the time of the clockwork movement, or with a correction gear 6 pivotally mounted at B on the movement. The main gear 5 as well as the correction gear 6 can have any suitable shape. In particular, they could each comprise several superimposed and integral teeth, added or in one piece, with identical or different modules or numbers of teeth, to allow the main wheel 5 to mesh with the time-setting wheel 33 and with the correction wheel 6 on different levels.

[0030] When the winding stem 1 is in its second pulled-out position or time-setting position as illustrated in Figure 6, the pull-out 12 is in its time-setting position pushed by the pull-out spring 13 against a stop of the corresponding clockwork movement and the control lever 14 of the sliding pinion 11 holds the latter in a position on the winding stem 1 in which said sliding pinion 11 meshes with the main gear 5 which is itself in a position in which it meshes with the timer train represented by the time-setting gear 33. The time-setting function is therefore also carried out conventionally.

[0031] The selection and actuation device according to the illustrated embodiment further comprises a selection wheel set 7 kinematically connected to the crown wheel 20. In the illustrated embodiment, the selection wheel set 7 comprises a selection cam 71 secured to and superimposed on a selection pinion 72 arranged to mesh with the crown wheel 20. The selection cam 71 drives a selection lever 8 pivoted on the movement at B concentrically with the correction wheel 6. The selection lever 8 carries a selection wheel 81 arranged to mesh with the correction wheel 6 regardless of the position of the selection lever 8.The selection lever 8 pivots - driven by the selection cam 71 - between a position in which the selection gear 81 is engaged with a first correction mechanism of which only the first wheel 91 is illustrated (figures 1, 2, 3 and 6) and a position in which the selection gear 81 is engaged with a second correction mechanism of which only the first wheel 92 is illustrated (figures 4 and 5).

[0032] Preferably, the first correction mechanism is arranged to allow the correction of a first mechanism of the watch movement when its first mobile 91 pivots in a first direction and the correction of a second mechanism of the watch movement when the first mobile 91 pivots in a second direction (one mechanism for two functions depending on the direction of rotation of the winding stem). The first and second watch mechanisms may be, for example, a date display mechanism and a month display mechanism. Similarly, preferably, the second correction mechanism is arranged to allow the correction of a third mechanism of the watch movement when its first mobile 92 pivots in a first direction and the correction of a fourth mechanism of the watch movement when the first mobile 92 pivots in a second direction.The third and fourth watch mechanisms can be, for example, a day of the week display mechanism and a moon phase mechanism.

[0033] Alternatively, one or both of the first and second correction mechanisms 91, 92 could be arranged to allow correction of a single watch mechanism of the movement in both directions (one mechanism for one function regardless of the direction of rotation of the winding stem). Such correction mechanisms are well known to those skilled in the art and will not be described here.

[0034] The operation of the above device for selecting and actuating the first and second correction mechanisms 91, 92 is described below.

[0035] In the illustrated embodiment, the non-selection position does not exist: at rest - the winding stem 1 in its pushed winding position - the device retains the last selection made. Thus, Figure 1 illustrates the device in a position in which the selected correction mechanism is the first correction mechanism 91.

[0036] To reach this position and select the first correction mechanism 91, the winding stem 1 must be axially moved into its first pushed winding position. The pull 12 is then in its winding position constrained by the pull spring 13 and the control lever 14 of the sliding pinion 11 holds the latter in a position on the winding stem 1 in which said sliding pinion 11 meshes with the winding pinion 2.

[0037] The pull-out 12 in its winding position does not actuate the time-setting lever 3 which is in its rest position maintained by its return spring 31. In this rest position of the time-setting lever 3, the pin 32 cooperates with the opening 41 of the correction lever 4 to maintain the latter in a correction position in which the main reference 5 does not mesh with the time-setting reference 33 but meshes with the correction reference 6.

[0038] Then, the winding stem 1 is pivoted in a first direction driving the sliding pinion 11, the winding pinion 2 and the crown wheel 20. The crown wheel 20 is engaged with a toothing 721 of the selection pinion 72 of the selection wheel set 7 and drives the latter. The selection cam 71 secured to the selection pinion 72 then pivots until a finger 711 of said cam 71 enters the fork 82 of the selection lever 8. By continuing its rotation in the same direction, the selection cam 71 then drives the selection lever 8 which pivots to reach its first selection position in which the selection return 81 meshes with the first correction mechanism 91. The selection cam 71 drives the selection lever 8 until an arm of the fork 82 of the selection lever 8 comes into abutment on the selection cam 71. This stop position is illustrated in Figure 1.

[0039] Thus, in this first device selection configuration, the first correction mechanism 91 is selected.

[0040] The selection pinion 72 also comprises a toothless section 722 and a detent spring 73 which is arranged to cooperate with a beak 712 of the selection cam 71. Thus, the selection wheel set 7 is arranged to be able to detent at the end of its travel if the winding stem 1 and therefore the crown wheel 20 continue to rotate in the first direction - winding direction - which makes it possible to select the first correction mechanism while the selection lever 8 has reached its first selection position in abutment on the selection cam 71.This unclicking position is illustrated in Figure 2: the crown wheel 20 continues to rotate driven by the winding stem 1 pivoted in the first direction, but at the end of its travel, when the selection lever 8 is in its first selection position in abutment on the selection cam 71, the crown wheel 20 cooperates with the toothless section 722 of the selection pinion to no longer drive the selection cam 71 while the unclicking spring 73 bearing on the beak 712 ensures that the teeth 721 of the selection pinion 72 remain in the path of the crown wheel 20 in order to be able to mesh with it when the winding stem 1 is turned in the other direction.

[0041] Preferably, the device - in particular the selection wheel 7 - is arranged so that the selection lever 8 reaches its first selection position in abutment on the selection cam 71 after approximately 1 revolution of the winding stem 1. Other choices are of course possible (more or less than one revolution). After having selected it, to actuate the first correction mechanism 91, it is now necessary to pull on the winding stem 1 (without turning it) to move it into its first pulled-out position as illustrated in Figure 3. From the configuration of Figures 1 or 2, the axial movement of the winding stem 1 into its first pulled-out position causes the rotation of the pull-out 12 at A into its correction position determined by its return spring 13. By pivoting, the pull-out 12 pivots the control lever 14 of the sliding pinion 11.The sliding pinion 11 is then moved axially on the winding stem 1 into a position in which it no longer meshes with the winding pinion 2 but meshes with the main wheel 5. In this correction position, the pull-out piece 12 and its arm 122 can come into contact with the time-setting lever 3 but do not drive it and this time-setting lever 3 remains in its rest position.

[0042] In this configuration of the device, by rotating the winding stem 1, the sliding pinion 11 drives the main setting wheel 5, the correction setting wheel 6, the selection setting wheel 81 and finally the first correction mechanism 91. Preferably, by rotating the winding stem 1 in a first direction, the first correction mechanism 91 corrects a first watch mechanism such as the date and by rotating the winding stem 1 in a second direction, the first correction mechanism 91 corrects a second watch mechanism such as the month display. Thus, in this first selection configuration of the device, it is possible to actuate two functions depending on the direction of rotation of the winding stem 1.

[0043] From the configuration illustrated in Figure 3, an axial displacement of the winding stem 1 into its first pushed position or into its second pulled position does not change the selected correction mechanism. In particular, by pushing the winding stem 1 into its first pushed position, the device resumes the configuration illustrated in Figures 1 or 2.

[0044] By pulling the winding stem 1 into its second pulled-out position, the device moves into a configuration illustrated in Figure 6. The pull-out 12 pivots into its time-setting position and its arm 122 actuates the time-setting lever 3 which pivots against the action of its return spring 31 from its rest position into its time-setting position. By pivoting, the pin 32 moves into the opening 41 of the correction lever 4 which pivots and moves the main setting wheel 5 into a position in which it meshes with the time-setting wheel 33 and no longer meshes with the correction wheel 6.

[0045] The selection lever 8 has not moved during the axial displacement of the winding stem 1. The control lever 14 of the sliding pinion 11 has continued its rotation pushed by the beak 123 of the pull rod 12, in doing so it slides the sliding pinion 11 on the winding stem 1 to keep it in a position in which it is engaged with the main wheel 5 which has moved.

[0046] Thus, in the configuration of Figure 6 when the winding stem 1 is in its second pulled-out time-setting position, a rotation of the winding stem 1 drives the sliding pinion 11, the main setting wheel 5 and the time-setting wheel 33. The kinematic chain starting from the correction wheel 6 and comprising the selection wheel 81 and the first wheel of the first correction mechanism 91 is not activated. In this position, it is therefore possible to perform a conventional time-setting by turning the winding stem 1 in one direction or the other.

[0047] To select another function to be actuated, in particular to select the second correction mechanism 92, the winding stem 1 must be moved axially to return it to its first pushed position. The device is then again in the configuration of figure 1.

[0048] From this configuration in which the first correction mechanism 91 is selected, the winding stem 1 must be turned in a second direction, opposite to the first. The winding stem 1 therefore pivots in a second direction and drives the sliding pinion 11, the winding pinion 2 and the crown wheel 20. Thanks to the detent spring 73, the toothing 721 of the selection pinion 72 is ensured to be in the path of the crown wheel 20. Thus, the crown wheel 20 drives the selection pinion 72 and the selection cam 71. In doing so, the finger 711 of the selection cam 71 again catches the fork 82 of the selection lever 8 and pivots it into its second selection position. The selection wheel 81 then meshes with the second correction mechanism 92.

[0049] The selection cam 71 drives the selection rocker 8 until an arm of the fork 82 of the selection rocker 8 comes into abutment on the selection cam 71. This abutment position is illustrated in Figure 4.

[0050] Preferably, the device - in particular the selection wheel 7 - is arranged so that the selection lever 8 reaches its second selection position in abutment on the selection cam 71 after approximately 1 turn of the winding stem 1. Other choices are of course possible (more or less than one turn).

[0051] Thus, in this second device selection configuration, the second correction mechanism 92 is selected.

[0052] This time, it is the finger 711 of the cam 71 which will cooperate with the release spring 73 to be able to release at the end of its travel if the winding stem 1 and therefore the crown wheel 20 continue to rotate in the second direction which makes it possible to select the second correction mechanism 92 while the selection lever 8 has reached its second selection position in abutment on the selection cam 71.The crown wheel 20 can continue to rotate driven by the winding stem 1 pivoted in the second direction, but at the end of its travel, when the selection lever 8 is in its second selection position in abutment on the selection cam 71, the crown wheel 20 cooperates with the toothless section 722 of the selection pinion 72 to no longer drive the selection cam 71 while the release spring 73 resting on the finger 711 ensures that the teeth 721 of the selection pinion 72 remain in the path of the crown wheel 20 in order to be able to mesh with it when the winding stem 1 is turned in the first direction.

[0053] After having selected it, to actuate the second correction mechanism 92, it is now necessary to pull on the winding stem 1 (without turning it) to move it into its first pulled-out position as illustrated in Figure 5. From the configuration of Figure 4, the axial movement of the winding stem 1 into its first pulled-out position causes the rotation of the pull-out 12 at A into its correction position determined by its return spring 13. By pivoting, the pull-out 12 pivots the control lever 14 of the sliding pinion 11. The sliding pinion 11 is then moved axially on the winding stem 1 into a position in which it no longer meshes with the winding pinion 2 but meshes with the main wheel 5. In this correction position, the pull-out piece 12 and its arm 122 can come into contact with the time-setting lever 3 but do not drive it and this time-setting lever 3 remains in its rest position.

[0054] In this configuration of the device, by rotating the winding stem 1, the sliding pinion 11 drives the main gear 5, the correction gear 6, the selection gear 81 and finally the second correction mechanism 92. Preferably, by rotating the winding stem 1 in a first direction, the second correction mechanism 92 corrects a third watch mechanism such as the day of the week display and by rotating the winding stem 1 in a second direction, the second correction mechanism 92 corrects a fourth watch mechanism such as the moon phase display. Thus, in this second selection configuration of the device, it is also possible to actuate two functions depending on the direction of rotation of the winding stem 1.

[0055] From the configuration illustrated in Figure 5, an axial displacement of the winding stem 1 into its first pushed position or into its second pulled position does not change the selected correction mechanism. In particular, by pushing the winding stem 1 into its first pushed position, the device resumes the configuration illustrated in Figure 4.

[0056] The device described above therefore makes it possible to:

[0057] • Select the first correction mechanism 91 by turning the winding stem 1 to its pushed position in a first direction;

[0058] • Pull the winding stem 1 into a first pulled-out position and o Correct a first watch display by turning the winding stem in a first direction; o Correct a second watch display by turning the winding stem in a second direction;

[0059] • Push the winding stem back into its first pushed position;

[0060] • Select the second correction mechanism 92 by turning the winding stem 1 to its pushed position in a second direction;

[0061] • Pull the winding stem 1 into a first pulled-out position and o Correct a third watch display by turning the winding stem in a first direction; o Correct a fourth watch display by turning the winding stem in a second direction;

[0062] • Push the winding stem into its pushed position to wind the motor organ, at any time, regardless of the correction mechanism selected;

[0063] • Pull the winding stem into its second pulled-out position for time setting at any time, regardless of the correction mechanism selected.

[0064] Depending on the arrangement of the first and / or second correction mechanisms, the above device could also be used to correct only a first and a second watch display but in both directions or a first watch display in both directions and second and third watch displays in one direction only. The device can therefore be used to correct four displays in one direction only, two displays in both directions or three displays including one display in both directions and two displays in one direction only. Generally speaking, a selection and actuation device according to the invention is arranged to be able to select and actuate at least two functions of a watch movement.The functions to be selected and activated may be functions for correcting one or more complications or one or more displays, a winding function for a driving organ such as a barrel or an adjustment function such as setting the time of a time display.

[0065] In particular, in the preferred case of the embodiment illustrated in the figures, the control member is arranged to take at least two distinct axial positions: a selection position and an actuation position. The device is arranged so that a rotation in a first direction of the control member in the selection position places the device in a first configuration in which a first function of the watch movement is selected. The device is arranged so that in this first selection configuration, the first selected function can be actuated when the control member is pivoted while it is in its actuation position. In the same way, the device is arranged so that a rotation in a second direction of the control member in the selection position places the device in a second configuration in which a second function of the watch movement is selected.The device is arranged so that in this second selection configuration, the second function can be actuated when the control member is pivoted while it is in its actuating position.

[0066] In a variant of the illustrated embodiment, it is possible to increase the number of functions actuable by the device, for example by adding one or more additional selection levers, each cooperating with a corresponding selection cam of the selection wheel set. The selection levers may or may not be superimposed. Each selection lever makes it possible to select between two distinct functions of a pair of functions of the watch movement. The control member is then arranged to take a selection position and as many axial actuation positions as there are pairs of distinct functions. In each of these actuation positions, a rotation of the control member causes the actuation of the function of the pair of functions selected by the corresponding selection lever.For example, starting from the above embodiment, a second selection lever pivoted concentrically to the correction wheel 6 and controlled by a second selection cam of the selection wheel set 7 can be added. The second selection lever carries a second selection wheel arranged to be in constant engagement with the correction wheel 6 and in engagement with a third mechanism for actuating a function C of the watch movement or a fourth mechanism for actuating a function D of the watch movement depending on the position of the second correction lever. In the pushed position of the winding stem, it is therefore possible to simultaneously select between the first and second correction mechanisms 91, 92 and functions C or D. Then, in the first pulled position of the winding stem, the first or second correction mechanism 91, 92 is actuated depending on what has been selected.In this case, the winding stem takes a third pulled position in which, by pivoting the stem, functions C or D can be actuated depending on what has been selected. It can be generalized to n selection rockers for n pairs of distinct functions and n axial actuation positions for the control member.

[0067] Even more generally, several selection positions can be provided, each allowing a function to be selected between two functions of one or more pairs of distinct functions of the watch movement and as many actuation positions as there are pairs of functions. Thus, the subject of the present invention is a device for selecting and actuation of n pairs of distinct functions of a watch movement, for n greater than or equal to 1. The device comprises a control member movable in translation and in rotation and arranged to occupy x axial selection positions for x ranging from 1 to n and n distinct axial actuation positions each associated with a determined pair of functions.In each of these x selection positions, the device is arranged so that a rotation in a first direction of the control member places the device in a configuration in which a first function of at least one of the n pairs of functions is selected and so that a rotation of the control member in a second direction places the device in a configuration in which the second function of the at least one of the n pairs of functions is selected.In each actuation position, rotation of the control member causes actuation of the first function of the associated pair of functions when the device is in a configuration in which said first function has been selected in the corresponding selection position or actuation of the second function of the associated pair of functions when the device is in a configuration in which said second function has been selected in the corresponding position.

[0068] In the illustrated embodiment, x and n are equal to 1: there is a single selection position which allows selection between two functions A or B forming a pair of distinct functions: correction A via the first correction mechanism 91 and correction B via the second correction mechanism 92. As discussed above, by adding for example an additional selection rocker superimposed on the first, we can consider the case where x = 1 (we keep a single selection position) and n = 2: there are two pairs of distinct functions (pair of functions A, B and pair of functions C, D). In the single selection position, we choose between A or B and simultaneously between C or D by pivoting the control member in one direction or the other. To actuate A or B, we must put ourselves in a first actuating position while to actuate C or D, we must put ourselves in a second actuating position.Alternatively, x can be 2 and there is one selection position for each of the function pairs: one selection position to choose between A and B and one selection position to choose between C and D. We can thus see that the number of selection positions can be between 1 and n where n is the number of function pairs for which we want to make a choice, since it is possible to simultaneously choose a function from each of the n function pairs while the number of actuation positions must be exactly n to be able to independently actuate the selected function from each of the n function pairs.

[0069] It is noted that the device can be arranged so that in the selection position(s), another function of the movement can be actuated: this is particularly the case in the illustrated embodiment, in which the selection position is the winding position, in which the device is arranged to enable the winding function of a motor member of the movement to be actuated.

[0070] Preferably, in the case where there is only one selection position and n actuation positions for actuation of the functions of n pairs of distinct functions, n greater than or equal to 1, the device comprises in particular

[0071] • A correction return intended to be pivoted on the clockwork movement comprising the device and kinematically connected to the control member in its actuation position(s);

[0072] • n selection rockers pivoted concentrically to the correction return;

[0073] • A selection wheel comprising n selection cams arranged to control the rotation of a corresponding selection rocker between a first and a second selection position: • n selection gears each pivoted on a corresponding selection rocker and arranged so that: o each selection gear meshes with the correction gear regardless of the position of the corresponding selection rocker;each selection gear is arranged to mesh with a first mechanism of the clockwork movement for actuating a first function of one of the n pairs of functions of said movement associated with the corresponding selection lever and selection cam in the first selection position of said selection lever and to mesh with a second mechanism of the clockwork movement for actuating a second function of said pair of functions of said movement associated with the corresponding selection lever and selection cam in the second selection position of said selection lever.;

[0074] The device is arranged so that:

[0075] • In the selection position of the control member, a rotation of said control member in a first direction causes a rotation of the selection wheel such that each selection cam moves and / or maintains the corresponding selection rocker in its first selection position;

[0076] • In the selection position of the control member, a rotation of said control member in a second direction causes a rotation of the selection wheel such that each selection cam moves and / or maintains the corresponding selection rocker in its second selection position; An axial movement of the control member from its selection position into one of its n actuating positions or vice versa does not cause the selection wheel or the selection rockers;

[0077] In each of the n actuation positions of the control member, the rotation of said control member drives the correction gear and the corresponding selection gear which is arranged to then actuate one or other of the first or second clockwork mechanisms depending on the position of the corresponding selection lever.

[0078] As seen in the illustrated example, the control member is preferably the winding stem arranged to take another axial position which is the time-setting position and which is distinct from the selection positions and the actuation positions, the winding position also acting as the selection position. The device is arranged so that the selection wheel set is not driven when the winding stem moves from one of its selection or actuation positions to its time-setting position or when the winding stem rotates into its time-setting position.

[0079] Preferably, the selection wheel is arranged to move the selection rocker(s) into their first, respectively second position after a rotation of the control member by an angle A in the first, respectively second direction and to maintain said rocker in this first, respectively second selection position without breakage when the rotation of the control member in the first, respectively second direction continues beyond this angle A (unlatching). To do this, the selection wheel preferably comprises a selection pinion arranged to be kinematically connected to the control member, secured to the selection cam(s) and having a toothed sector and a toothless sector while the selection cam is subjected to the action of a unlatching spring.Preferably, the angle A is less than 360°, is preferably between 150° and 250° and is even more preferably around 200°: it is thus possible to indicate to the wearer of the watch that it is necessary to make one turn of the stem (simple indication which avoids having to count turns, which would be tedious) while maintaining a safety feature (included in the difference between 360° and 200° for example and / or the ratio between the winding pinion 2 and the selection pinion 72) in order to guarantee that the selection is made.

[0080] The selection and actuation device according to the invention is simple, compact and allows the selection and actuation of at least two functions of a watch movement, and in particular the correction of complications, using a single control member, which is preferably the winding stem. The aesthetics of the timepiece are thus preserved while offering selection and actuation operations that are easy to implement for a user. In addition, the function selection sequence is simple (put the control member in its selection position, turn the control member one turn in one direction) which makes it possible to do without a display device for the selected function while avoiding the user having to remember the last function selected since he can always simply select the function to be activated.
