    Technical area
    The present invention relates to a display mechanism for a timepiece, intended to allow the display of predefined information in the form of successive display cycles of integer values i, with a ≤ i ≤ b, the display mechanism comprisingc display mobiles, with c ≥ b, each of which is intended to control at least one display device in order to change it from a first state, inactive, to at least a second state, active, and vice versa, the number display units being in an active state at a given instant corresponding to the value i to be displayed,a drive mechanism, intended to be connected to a driving wheel set of a watch movement and arranged to drive at least one of the display mobiles in order to be able to change the state of the corresponding display member (s) (s) at each change of the value i to display.
    [0002] The invention also relates to a watch movement and to a timepiece comprising such a display mechanism.
    State of the art
    [0003] Various display mechanisms meeting the above characteristics are already known, in particular for producing a display of the current time.
    [0004] By way of illustration, patent CH705806B1 describes such a display mechanism intended to be implemented in a wristwatch in connection with a watch movement adapted to ensure its operation. More particularly, this display mechanism comprises a peripheral crown driven by a basic watch movement to ensure the driving of twelve mobile display of the current time, distributed in an identical manner to that of the conventional index indicating the clock. current time. Each current time display mobile carries a display member so as to be able to rotate it between a first, active state in which it has a first face, and a second, inactive state, in which it has a second side. At any time, only one display member at a time is in its active state to indicate the current time by a conventional reading of the position of this active display member. At each time change, the drive crown actuates the moving parts for displaying the current time to modify the display member which is in its active state.
    This display mechanism uses the general principle of displaying the current time by an hour hand and it remains desirable to produce an original display mechanism based on a principle of displaying predefined information. deviating more clearly from the principles currently used.
    [0006] Patent application EP 2365406 A2 presents another type of display mechanism which, in addition to the display of the current time over twelve hours, makes it possible to distinguish the hours extending from noon to midnight. extending from midnight to noon. For this purpose, this display mechanism comprises twelve sectors distributed radially around the dial in the conventional directions for indicating the hours. The mechanism is arranged to be able to rotate the sectors by 180 degrees in turn, in their longitudinal direction, during the passage from one hour to the next, to display one or the other side of the different sectors according to the the time to display. Indeed, each sector has a light face, used for example to display the hours extending between midnight and noon, and a dark face, to display the hours extending from noon to midnight. Thus, in a certain way, each sector carries two display elements of the time, a light and a dark, interchanged in turn, every twelve hours, to pass one of the display elements of the hour. 'from an inactive position, in which it is invisible, to an active, visible position, and vice versa.
    However, this display mechanism can be disturbing for the user insofar as, most of the time, some inactive display members are hidden while other inactive display members remain visible, which makes reading the corresponding information confusing. Thus, for example, if we consider the example illustrated in Figure 2 of this document, corresponding to the thirteen o'clock display, a single dark display member is in its active position while eleven display members clear are also visible, while the time indication is performed by the only dark display member, the bright display members being visible for the sole purpose of preventing the dark display members associated with them to be themselves visible. The display members being linked two-by-two, each of them can therefore have an invisible position, associated with an inactive state, and two different states in its visible position, either it is actually active, or it is visible without be active for all that, but for the sole purpose of masking the other display unit to which it is linked.
    [0008] Consequently, despite its repetitive mode of operation, such a display mechanism requires a long adaptation time and may not be suitable for all users, since out of twelve permanently visible display members, regardless of time, only some are actually active to display the current time value. This requires having differentiated display units, in order to be able to distinguish the value of the information displayed from the number of display units appearing to be in their active state at a given instant, this number then being greater than the value actually. displayed.
    Disclosure of the invention
    [0009] A main aim of the present invention is to provide a mechanism for displaying predefined information for a timepiece allowing a less conventional display of this information than the known display mechanisms, while offering a mode of display. easy reading.
    To this end, the present invention relates more particularly to a display mechanism of the type mentioned above, characterized by the factthat the drive mechanism comprises a programming device designed to give rise to at least first and second sequential display cycles, each of which is associated with a group of i predefined display mobiles for each value i to be displayed, of such that only the corresponding display elements are in their active state, andat least one of the predefined groups of the first display cycle, associated with a given value i, is different from the predefined group of the second display cycle which is associated with this same given value i.
    Thanks to these characteristics, it is possible to produce a timepiece having an original display of predefined information, giving watchmakers greater freedom in the arrangement of the corresponding display mobiles than with the mechanisms. of the prior art, the display according to the invention thus being able to be clearly distinguished from conventional displays.
    It will be noted that, according to the present invention, different display mobiles are requested during two successive display cycles, thus giving rise to a significant variation in the corresponding display. In a different manner in the construction of the application EP 2365406 A2 mentioned above, the same display mobiles are requested to display a given value i during successive display cycles, each display mobile controlling the position of two d members. 'display whose respective states are linked to one another, since necessarily opposed at every moment. It will also emerge from the following description that, in the context of the present invention, all the display members remain visible even when they are in their inactive state, unlike this prior display mechanism. It is thus easy for the user to distinguish how many display members are active at each instant in order to determine the displayed value. In addition, the display members according to the present invention are advantageously arranged such that each of them presents a projection in the plane of the dial (or in a plane corresponding to a hypothetical dial plane in the absence of a dial. ) separate from the projections of other displays. Thus, the active or inactive state of each display member according to the invention is only dictated by the programming device and is not dependent on the state of the other display members as is the case in the case of the programming device. prior display mechanism, therefore providing more flexibility in the appearance of the display. In other words, the present invention is further distinguished, in practice, from the prior mechanism mentioned above by the possibility of having at least two given display members which would present the same state (active or inactive) for a given value i during of a first display cycle and which would present different states (one active and the other inactive) for this same value i during another display cycle.
    According to a preferred embodiment, the programming device is arranged to present at least one, optionally at least two additional sequential display cycles, each of which is associated with a group of i predefined display mobiles for each value i to be displayed, so that only the corresponding display units are in their active state. According to this embodiment, it is then advantageously provided that at least one of the predefined groups of each of the additional display cycles, associated with a given value i, is different from the predefined group of each of the other display cycles which is associated with this same given value i.
    It is understood that, if a basic principle of the display mechanism according to the present invention is to present at least two sequential display cycles, providing an impression of display diversity for an observer, when the number of different sequential display cycles increases the impression of diversity can turn into a random display impression, in any case pseudo-random. This printing will of course also depend on the number of values i to be displayed per display cycle, on the duration of each display cycle, and on the number of display members.
    In general, when the programming device is arranged to give rise to at least two sequential display cycles, provision can be made for each of the predefined groups of the first display cycle to be different from the corresponding predefined group of the second cycle display, for i> 0 and, for i <b when c = b.
    When more sequential display cycles are implemented, one can advantageously provide that the programming device is arranged to present a maximum of b display cycles, and that each of the predefined groups of each of the cycles of display is different from the corresponding predefined group of each of the other display cycles, for i> 0 and, for i <b when c = b.
    According to additional preferred features of the present invention, provision can also be made for the programming device to include at least one cam capable of occupying a plurality of different angular orientations, each of which is associated with one of the cycles of. sequential display and to one of the values i to be displayed in the corresponding display cycle, this cam being arranged to cooperate with the c display mobiles and to drive at least one of the display mobiles, at each change of the value i to display, in order to be able to change the state of the corresponding display device (s).
    Provision can be made for the display mechanism to include one cam per cycle or for the cam (s) to be associated with several cycles at the same time, preferably to all in this case.
    As an alternative, it is possible to provide that the programming device comprises at least two cams, each of these cams being capable of occupying a plurality of different angular orientations, each of which is associated with one of the cycles of. sequential display and to one of the values i to be displayed in the corresponding display cycle, each of these cams being arranged to cooperate with at least one of the display mobile cs and to drive it in order to be able to change the state of the display member (s) corresponding to each change in the value i to be displayed, the set of cams being arranged to drive all of the c mobile display units.
    In both cases, provision can also be made for the display mechanism to include at least one latch associated with each of the cams, each latch comprising a feeler arranged to cooperate with the periphery of the corresponding cam and a toothing having a connection kinematics with at least one of the mobile display c.
    In general, the display mechanism according to the present invention can be implemented in relation to predefined information of periodic type, each of the sequential display cycles then corresponding to a period of this predefined information.
    According to a preferred embodiment, the drive mechanism then comprises at least one trigger mobile arranged to be able to be actuated periodically from the watch movement and ensure the training of at least one of the display mobile c at each change of the value i to display.
    According to this preferred variant embodiment, the trigger mobile has a particularly advantageous construction. The latter is part of a triggering device which can be adapted to trigger any other watch mechanism than the display mechanism according to the present invention.
    The present invention also relates to a watch movement comprising an energy source arranged to supply energy to a driving mobile arranged to ensure the operation of a display mechanism according to the above characteristics, as well as a timepiece provided with such a display mechanism.
    [0025] According to a preferred embodiment, the timepiece comprises at least twelve display members, controlled by the display mechanism as described above, to display the current time.
    Brief description of the drawings
    Other characteristics and advantages of the present invention will emerge more clearly on reading the detailed description of a preferred embodiment which follows, made with reference to the appended drawings given by way of non-limiting examples and in which :FIG. 1 represents a simplified front view of part of a timepiece comprising a display mechanism according to a preferred embodiment of the invention;FIGS. 2a and 2b represent slightly simplified perspective views of a part of the timepiece of FIG. 1, respectively from a first face and from the opposite face;FIGS. 3a and 3b represent simplified front views of part of the display mechanism of the timepiece of FIG. 1, respectively from a first face and from the opposite face, while FIGS. 3c and 3d represent simplified views, respectively in perspective and in cross section, of a detail of the construction of this same display mechanism, and that FIG. 3e represents a simplified perspective view of a detail of the construction of the illustrations of FIGS. 3a to 3d, andFIGS. 4a and 4b represent simplified perspective views of a construction detail of the display mechanism of the timepiece of FIG. 1, respectively from a first face and from the opposite face.
    Mode (s) for carrying out the invention
    [0027] FIG. 1 represents a simplified front view of part of a timepiece 1 comprising a display mechanism according to a preferred embodiment of the invention. The exact nature of the timepiece 1, whether it is for example a wristwatch or a pocket watch, does not matter for the implementation of the present invention, so the trim components are not illustrated on FIG. 1 for the sake of simplification.
    The timepiece 1 comprises a box (not visible) in which is arranged a watch movement 2 (Figure 2a), which will be partially described later, with which cooperates in particular a time setting rod 4 , and possibly reassembly, by way of nonlimiting illustration.
    The watch movement 2 is surmounted by a dial 6, itself being surmounted by a plurality of display members 8 whose movements are controlled by the watch movement 2, as will be explained below.
    The display members 8 are intended to display the current times at each moment and are twelve in number in the timepiece 1 shown in Figure 1, by way of illustration. It will be understood hereinafter that more than twelve display members 8 could be provided to display the current times without however departing from the scope of the present invention. Each of the display members 8 here has the shape of a flower with five petals 10 by way of non-limiting illustration. The display mechanism according to the preferred embodiment allows the display members 8 to be controlled such that their petals 10 can move, preferably simultaneously, between a first position defining an active state of the display member. display 8 and a second position defining an inactive state of the display member 8. Thus, in FIG. 1, five display members 8 represent an open flower associated with the active state, while each of the other seven members display represents a closed flower associated with the inactive state. The display mechanism therefore indicates that it is five o'clock in the configuration shown in Figure 1.
    It appears that, according to the preferred embodiment illustrated, all the display members 8 remain permanently visible, whatever their state, active or inactive.
    It is also understood that each of the display members 8 has a projection in the plane of the dial 6 which is distinct from the projections of the other display members 8.
    [0033] According to a variant, the position of the petals of each display member can be controlled independently and the flowers, as display members, can have several active states so that each active state has a different number of petals. in open position. In this way, if for example the display members each have six petals, the state of at least one of the active display members can also indicate tens of minutes. For example, at 5:10 a.m. we find ourselves with five display members in an active state with all their petals open and a sixth display member in an active state with an open petal, this sixth display member successively transforming into an active state with another petal open every 10 minutes. According to this variant, the petals can also be considered themselves as display members.
    Of course, the display members 8 could have any other type or form suitable for displaying predefined information such as current times. Moreover, it can be seen here that the flowers shown in FIG. 1 are not all of the same species. Those skilled in the art will not encounter any difficulty in choosing alternative display members that meet their own needs or, when the display members represent flowers, in using a different number of petals, or even in implementing different ones. different numbers of petals from one flower to another, without departing from the scope of the present invention. As an example, the display organs could take the form of a bird or an insect (such as a butterfly) with pivoting or movable wings where each organ is in an active state when its wings are outstretched. .
    As will emerge from the remainder of this presentation, the petals 10 are here arranged to pivot when the corresponding display member 8 changes from one state to another. It is possible to provide other types of movement of the petals as an alternative such as, for example, an oscillating translational movement.
    Figures 2a and 2b show slightly simplified perspective views of part of the timepiece 1 without its dial 6. More specifically, Figure 2a shows the timepiece 1 in a view from the side dial, while FIG. 2b represents timepiece 1 in a view from the bridges side, with a few components less than in the view of FIG. 2a, these two figures making it possible to show the construction of the drive mechanism used to control the behavior of display devices 8.
    In general, the illustrations are simplified for greater clarity and to facilitate understanding. Thus, in particular most of the components not directly involved in the implementation of the invention are not shown.
    The time setting rod 4 is kinematically connected to a basic watchmaking caliber, partially shown, in a conventional manner and it preferably also makes it possible to recharge the spring of a barrel 20 fulfilling the function of energy source mechanics of mechanical watch movement 2.
    The drum of the barrel 20 is arranged in engagement with a roadway 22 connected to a toothed peripheral ring 24 for the minutes, by means of two references 26 and 28, such that the ring 24 makes a turn on it- even in one hour, three screws 30, each associated with a washer, ensure the axial retention of the crown 24 with reference to the rest of the watch movement 2, that is to say in the direction of the thickness of the watch movement 2 .
    By way of example, provision could be made for the crown 24 to carry an index intended to ensure the display of the current minutes when the crown 24 rotates, possibly in relation to the graduations carried by the dial 6 or the box of the timepiece 1. In variants, crown 24 can rotate at a slower speed, performing one revolution in N hours, for example in four hours. In this case, the crown 24 can include N sets of minute graduations, only one being visible at a time in a window made in the middle part of the watch case and cooperating with a fixed minute mark.
    The display mechanism according to the present invention also comprises a winding mobile 32 of which the winding wheel 34 is arranged in engagement with the teeth of the crown 24 of the minutes to ensure the drive of the bodies. display 8.
    For this purpose, the winding mobile 32 has a kinematic connection, via its pinion 36 integral in rotation with the winding wheel 34, with a periodic tripping device 38 which will be described later in relation with Figures 4a and 4b. This periodic tripping device is designed to drive a control wheel 40 once an hour, following a fraction of a turn.
    On the one hand, the control wheel 40 meshes with a conventional speed control train 42, here comprising an inertial speed control wheel 44, so that its speed of rotation is regulated when the trigger device periodic 38 rotates it once an hour.
    On the other hand, the control wheel 40 meshes with the wheel 46 of a distribution wheel set, the pinion 48 of which is simultaneously engaged with the respective large wheels 50 of two operating wheels 52, each of which is arranged to control six display mobiles 54 (FIGS. 3a and 3b), by means of a suitable programming device, as will be explained in more detail now, in relation to FIGS. 3a and 3b.
    Figures 3a and 3b show simplified front views of the end part of the display mechanism, on the side of the display members 8, in respective views on the bridge side and on the dial side.
    Each mobile actuator 52 comprises a second wheel 56, smaller than the corresponding large wheel 50 while being integral with the latter in rotation, and has a kinematic connection with the six mobile display 54 corresponding by the intermediary of two distribution mobiles 58, each of which is connected to three display mobiles 54.
    Each distribution mobile 58 comprises a pinion 60, engaged with the large wheel 50 of the corresponding actuating mobile 52, and a wheel 62 engaged with the second wheel 56, smaller, of the same actuating mobile 52 .
    Figures 3c and 3d show simplified views, respectively in perspective and in section, illustrating the construction of each distribution mobile 58.
    The pinion 60 is integral with a barrel 64 which is also integral with a star 66 with nine branches substantially sawtooth and with a truncated end.
    The star 66 rests on a shoulder 68 of the barrel 64, making it possible to define a central portion 70 of the barrel on which is engaged a ring 72 carrying, integrally, the wheel 62 and a cam 74 intended to define the state, active or inactive, of the three display members 8 controlled by the corresponding display mobiles 54. The ring 72 is free to rotate on the barrel 64.
    FIG. 3e represents a simplified perspective view of the cam 74 according to the present preferred embodiment of the invention, by way of non-limiting illustration.
    The cam 74 comprises a central hole 76 allowing its attachment to the barrel 64 and has substantially the general shape of a disc in which recesses of variable angular extent are formed, so as to define two different radii for its periphery, a large radius R for the non-recessed portions and a small radius r for the portions located at the bottom of the recesses. The non-recessed portions are connected to the recessed portions by slightly curved substantially radial junctions.
    It emerges from the above that the cam 74 is driven in rotation from the second wheel 56 of the actuating mobile while the star 66 is driven from the large wheel 50 of the same mobile, here with gear ratios such that the cam 74 makes one revolution on itself in thirty-six hours and the star 66 makes one revolution on itself in nine hours.
    It appears more particularly from Figure 3c that each distribution mobile 58 cooperates with three rockers 80 comprising a feeler 82 at one end and a toothed rake 84 at the other end. Each lever 80 is associated with a return spring 86 (FIG. 3a) arranged to act on it so as to keep its feeler 82 bearing against the periphery of the corresponding cam 74.
    Each rake 84 cooperates with a first wheel 88 of a display mobile 54, the latter comprising a second wheel 90, integral with the first wheel 88 and arranged in engagement with five petal wheels 92, as illustrated in the Figures 3a and 3b, each of which has a petal 10.
    Thus, when the cam 74 rotates, by one step every hour, it acts on the latches 80 to rotate them between two extreme positions, if applicable, one of which is associated with the active state of the corresponding display member 8 and the other in its inactive state, by rotating the petals 10 in one direction or the other.
    It will be noted that according to the present preferred embodiment, each probe 82 has a sufficient thickness to cooperate simultaneously with the cam 74 and with the star 66. The branches of the star 66 are thus shaped and arranged in such a way that they can guide the movement of each feeler 82 with which they cooperate, during each jump from a portion of large radius R to a portion of small radius r of the periphery of the cam 74, so that the transition from the closed configuration towards the open configuration of the flowers, i.e. from the inactive state to the active state of the display members 8, takes place more gradually than the reverse change. After a transition, the feelers 82 are preferably resting against the periphery of the cam 74 and not on the star 66.
    It emerges from the above that three sequential or successive display cycles, of twelve hours each, are provided, since the cam 74 makes one complete revolution in thirty-six hours. Of course, another number of cycles can be provided, for example five cycles with a sixty hour cam. It is also noted that each display cycle is associated with a group of i display mobiles 54 for each value of i to be displayed. Each portion of the periphery of the cam 74 associated with a display cycle of twelve hours being different from the other two portions of twelve hours, it appears that at least one of the groups of a given display cycle, associated at a given value i, is different from at least one of the groups of the other two display cycles which is associated with this same given value i.
    Concretely, this means that for at least one given value of the hour, three different groups of display members 8 are in their active state during three successive display cycles of twelve hours. In other words, the display of the current hours here presents a period of thirty-six hours instead of the conventional twelve hours. Thus, for example, for the indication of daytime hours, the flowers open at a given time will only be the same every other day.
    Note that if the timepiece 1 has twelve display members 8, a single group is defined to display twelve hours. It is however possible to provide that the timepiece 1 comprises more than twelve display members 8 and, in this case, it is possible to define several different display groups on successive cycles even to display twelve hours.
    Figures 4a and 4b show simplified perspective views, respectively from a first face and from the opposite face, of a preferred construction detail of the display mechanism of the timepiece 1, namely of the device periodic tripping 38.
    The triggering device 38 comprises a load mobile 100 comprising a pinion 102 arranged simultaneously in engagement with the pinion 36 of the winding mobile 32 and with a load wheel 104 of a trigger mobile 106, including a pinion 108 is engaged with the control wheel 40 to act on the display members 8.
    The load mobile 100 further comprises a wheel 110 engaged with a locking cam mobile 112. The locking cam mobile 112 also comprises a double cam 114 with two stages each of which has substantially the general shape of a half. -disk.
    The load wheel 104 of the trigger mobile 106 is secured to a first end of a spiral spring 116, the second end of which is indirectly secured to the pinion 108.
    Furthermore, the trigger mobile 106 comprises a locking wheel 118 with four teeth 120, 122, also integral in rotation with the pinion 108. Two teeth 120, diametrically opposed, are located at the same height level as the floor lower (in the view of Figure 4a) of the double cam 114 of the locking cam mobile 112, while the other two teeth 122, also diametrically opposed, are located at its upper stage.
    When the load mobile 100 is rotated by the winding mobile 32, it rotates both the load wheel 104 of the trigger mobile 106 and the double cam 114 of the locking cam mobile 112 , with differentiated gear ratios.
    In the configuration illustrated in Figure 4a, a tooth 120 is arranged to bear against a locking portion of the lower stage of the double cam 114, of substantially constant radius, ensuring a locking of the pinion 108, or a locking of the second end of the spiral spring 116. The locking wheel 118 is then in a locking position. Thus, the rotation of the load mobile 100 causes a progressive load of the spiral spring by rotating the first end of the latter with the load wheel 104.
    After one hour, here, when the blocking cam mobile 112 has made a U-turn on itself under the effect of the driving of the load mobile 100, the periphery of the double cam 114 has a free portion, of radius smaller than that of the locking portion, and releases the tooth 120. The locking wheel 118 becomes free to rotate under the effect of the action of the spiral spring 116 which then tends to discharge. The locking wheel 118 thus rotates until the next tooth 122 abuts against the periphery of the upper stage of the double cam 114, that is to say against its locking portion, to again lock the pinion 108 during a new half-turn of the locking cam mobile 112, by defining a new locking position of the locking wheel 118. This cycle is thus repeated indefinitely, causing a modification of the state of at least one member display 8 on each triggering, that is to say on each half-turn of the locking cam mobile 112.
    Note that the trigger mobile 106 further comprises a non-return pinion 124, sawtooth, cooperating with a right spring (reference 126 in Figure 2a) and integral with the shaft 128 of the trigger mobile 106, to allow setting the time in the anti-clockwise direction of rotation without the spiral spring 116 being able to discharge.
    Thanks to this construction, the periodic tripping device 38 is particularly energy efficient by the nature of the contact implemented between the teeth 120 and 122 of the locking wheel 118 and the periphery of the double cam 114. In furthermore, this construction is particularly compact.
    It will be noted that the construction of the trigger device 38 could advantageously be implemented in association with any other clock mechanism than the display mechanism according to the present invention, which constitutes only one example of particular application thereof. without limitation, the triggering device 38 making it possible to control the triggering of a timepiece mechanism of any type in response to the occurrence of a particular predefined event.
    According to the variant embodiment illustrated without limitation, each stage of the double cam 114 is defined by a cam having a single locking portion of constant radius, intended to cooperate with two of the teeth of the locking wheel 118, and a single free portion with a radius smaller than that of the locking portion so that it is located outside the reach of the teeth of the locking wheel 118. However, other embodiments can be envisaged such as for example by providing a number different teeth on the locking wheel, a different number of locking portions and free portions on each cam of the double cam or having more than two stages and levels for the cam (which would therefore no longer be a double cam but a cam block) and the locking wheel (for example a cam block comprising three stages of cams cooperating with a locking wheel comprising three levels of teeth). Likewise, the trigger mobile 106 and the locking cam mobile 112 are driven here by one and the same mobile 100, but it is conceivable that these two mobile are driven by two separate mobile.
    Thanks to the characteristics which have just been described, it is possible to produce a timepiece comprising an original display mechanism, flexible from the point of view of its design, in particular of the location of the display members. corresponding, and likely to present a new kinematics giving an impression of random display or almost.
    The foregoing description attempts to describe a particular embodiment by way of non-limiting illustration and the invention is not limited to the implementation of certain particular characteristics which have just been described, such as for example the nature and the whole of the construction of the drive mechanism of the display members, or the form illustrated and described for the display members.
    In general, it will be noted that the invention is not limited by the nature of the information displayed and therefore by the number of corresponding display members. In addition, it is important to remember that the number of display members used is not necessarily limited to the number of different values that the information to be displayed is likely to take. Thus, in the case of the preferred embodiment which has been described and illustrated, it is conceivable to provide that the display mechanism drives more than twelve display members to indicate the current times, and those skilled in the art will not encounter no particular difficulty in adapting the present teaching according to its own needs without departing from the scope of the present invention.
    The distribution of all of the display members into different subassemblies is not essential either to take advantage of the present invention, and those skilled in the art will also be able to adapt the number of cycles provided on the one or more. cams triggering the change of state of the display members according to its own needs without departing from the scope of the invention. It will be noted for example that the maximum number of probes associated with a given cam will also depend on the dimensions of this cam, which could influence the implementation or not of a possible distribution of the set of display members into different sub-sets. . Furthermore, it will be noted that a person skilled in the art will be able to implement various alternative constructions without departing from the scope of the invention as regards the programming device. Thus, for example, a single cam could be provided to control all of the display members, or even a cam could be provided for each of the sequential display cycles, a mechanism making it possible to change the cam by changing from one to the other. sequential display cycle to the next. Furthermore, at least one programming wheel or star comprising unevenly distributed teeth or teeth of different heights could be used instead of a cam to control the states of the display members.
    In general, the display mechanism according to the present invention can be integrated directly into a watch movement or be designed as an additional module cooperating with a standard basic watch caliber without departing from the scope of the invention.
