    Field of the invention
    The invention relates to an analog display timepiece comprising a watch movement provided with a mechanical output, located on an axis of said movement, and a display assembly provided with at least one time display device driven by said mechanical output, the display assembly being separated from the clockwork movement and connected to a fixed part of this movement by support means which allow several different positions of said display device around of the output axis of the movement.
    Background of the invention
    A manufacturer, to rationally produce different models of watches, uses in a known manner the same model of watch movement (in other words a "caliber") in combination with different display sets. Each of these sets comprises the desired display members (hour, minute and second hands, date indicators, chronograph hands, etc.) and the gearing necessary to drive these members from one or more mechanical outputs of the movement. . Such a set is commonly called a "module", because it is often intended to be able to replace it with a different module on the same clock movement, called "basic movement".
    In the context of a varied production, the use of a display module distinct from the basic movement allows in particular to use an off-center display device, for example a small second, or change the module for changing the type of display, for example with a retrograde hand, or to add a display device, for example a display 24 hours, without having to develop each time a new movement.
    However, such a module is designed for one or more predefined display functions and, if we want to produce a modified watch model, it is obviously necessary to modify the display module, which induces a reengineering of the module while complicating production and storage by increasing the number of component references.
    Summary of the invention
    The object of the present invention is to overcome all or part of the disadvantages mentioned above by providing a modular display system for timepieces and, in particular for watches, offering an expanded modularity to allow to mount one or more display devices, of different types, on a single basic motion model whose output drives the display assembly. This display system according to the invention, which can be called "configurable", makes it possible to maintain a modular construction while providing additional flexibility as to the positioning of the display devices, as well as to the diversity and the combination of them.
    For this purpose, the invention relates to an analog display timepiece comprising a watch movement and a display assembly provided with at least one display device of said analog display driven by said movement. , the display assembly being separated from the clockwork movement and linked to a fixed part of this movement by support means arranged to fix several types of said at least one display device characterized in that the watch movement comprises a drive mechanism of a calendar display and in that the calendar display comprises a drive disk geared to said movement and connected by spacing means to a display disk for presenting the display of the calendar closest to said analog display substantially compensating for the thickness of said at least one display device.
    Advantageously, the invention avoids the well phenomenon that is to say the impression that the display is at the bottom of a cavity opened by the window D. In addition, according to the alternatives, it is possible to be able to keep the integrated disc of the basic movement (drive disk) and to be able to associate it with any kind of display using the interchangeable disk of color, material and / or different height ( display disk). It is also possible to swap the display disk without disassembling the drive disk to adapt the calendar displays to a special series, collection modification, or thicker display modules / devices.
    According to other advantageous features of the invention:the display disk, the spacing means and the drive disk are monobloc;the fixing means are of the tenon-mortise and / or bayonet and / or groove-hook type;the display disk and / or the spacing means are formed from a lower density material than that of the drive disk to reduce the overall inertia of the calendar display;the display disk and the spacing means are monobloc;the drive disk is formed from a metal or a metal alloy in order to make the training of the calendar display reliable.

    Detailed Description of the Preferred Embodiments
    The exemplary embodiment illustrated in FIGS. 1 to 4 comprises a time display of the type called "regulator", shown schematically in FIG. 11, with a minute hand M in the center, an hour hand H off-center and shorter than the minute hand, and a second hand S which is here a small second, off-center to the opposite of the needle of the hours. Advantageously according to the invention, it will be seen later that the axes of the needles H, M and S, aligned in FIG. 11, can be positioned completely independently of each other.
    It is further provided a calendar display comprising here a date disc appearing in a window D of the dial. As usual, the manufacturer can place this window in any position on the periphery of the dial. Of course, the display of the date by another type of display is also possible as, for example, using a needle.
    As mentioned above, the timepiece, a watch described here, comprises a basic movement 1 called, current type, and various display devices driven by this movement 1, but can be arranged in different configurations to allow making watches with different displays with the same mechanical components. The basic movement 1 can be any mechanical or electromechanical watch movement, for example quartz.
    The base movement 1 thus comprises a mechanical output of geometric axis 2, generally a roadway and in the figures presented above an axis of the seconds inside the roadway. Among the elements of the basic movement 1 which appear in a first embodiment illustrated in FIGS. 1 to 4, there may be mentioned a fixed portion 10, here the plate, a second axis 11 provided with a seconds wheel 12 and guided by means of a fixed tube 9, a roadway 13, a driving wheel 14 and an hour wheel 15 driven by the toothing 13a of the roadway 13 via the usual timer train (not visible in the drawings). We can also see a control rod 16 provided with a ring 16a, and a corrector wheel 17 and a corrector gear 18 which are controlled by the rod 16.
    Therefore, the second axis 11 and the roadway 13 constitute the mechanical output to cause the display of the time. In the example of fig. 1 to 4, it is noted that the mechanical output is at the center of the movement 1, advantageously according to the invention, however, this is not a mandatory feature. It is therefore understood that the hour wheel 15 of the basic movement 1 is not used directly for the display of the time, that is to say that no needle is integral. However, the hour wheel 15 is used, in known manner, to cause the calendar display in the usual manner by means of a wheel (not visible in the drawings) making one turn per day and, according to the invention for driving at least one display device.
    In figs. 1 to 7, the display of the calendar is formed by means of a date ring 20. This ring is here in two stages, with two annular disks 21 and 22 connected by pillars 23 forming spacer means. In the usual way, the movement 1 comprises a lower disc 21 provided with an internal toothing is slidably mounted on the plate 10. According to the invention, the calendar display surrounds the display devices and comprises a second annular disc 22 mounted on the first 21 according to the spacing of the pillars 23 substantially corresponding to the thickness of the display assembly in order to present the display of said calendar on the second annular disk closest to said analog display, that is, that is to say, as shown in fig. 8 to 18, as close as possible to the window D. Therefore, in the example of FIGS. 1 to 7, the display of the calendar presenting the date, the upper face of the disc 22 carries the thirty-one calendar days.
    The current time is indicated by means of a time display assembly 30 (shown in FIG 11) comprising at least one display device and, preferably, two independent display devices, each of which is driven. individually by the output of the base movement 1 and reported on a fixed part 10, here the plate, of the movement 1 by means of support. A first device can thus be driven from the roadway 13 and display the hour and the minute, by means of the needle H and the needle M. The second device can be driven from the axis of seconds 11 and display the second using the S needle. It is quite possible, however, that a single display device can drive the three hands H, M, S or that it displays less information .
    In the example of FIGS. 1 to 4 representing a first embodiment, the needle H is off-center at 12 o'clock, the needle M is in the center and the needle S forms a small second at 6 o'clock. This display configuration is shown in FIG. 11. According to the first embodiment, the display assembly comprises two display devices 31 and 32 which are connected to a fixed part 10, here the plate, of the movement 1 by support means. These include an intermediate support and support members.
    Preferably, the intermediate support is formed by an at least partially circular rail 34 centered relative to the axis 2 and fixed to the fixed portion 10 by screws 35. The rail 34 here has a flat shape. The support members comprise, in this case, in addition to its upper and lateral surfaces, twelve stage orifices 36 adapted to receive screw feet 37 so as to fix on the rail 34 at least one display device in different positions, on manufacturer's choice. In the example of fig. 1 to 4, the orifices 36 are regularly spaced, with an angular pitch P which is here 30 °. The manufacturer thus has twelve possible positions for each display device 31, 32 of the display assembly 30.
    In the example of FIG. 1, it can be seen that each display device 31, 32 is fixed to the rail 34 by means of two screws 38 associated with the screw feet 37 and that six of the orifices 36 remain free, allowing these devices to be moved, or to fix a or more display devices. It is therefore immediately apparent that the invention makes it possible, advantageously, once the first display device 31 is fixed on the rail 34, to still offer many possibilities for placing the second display device 32 in different positions along of the rail 34, at the choice of the manufacturer thanks to the support members formed by the orifices 36 still free. This will appear later with reference to FIGS. 16 and 17.
    Of course, if the manufacturer wanted to have a greater number of possible positions of the devices, it could simply use a rail having a greater number of orifices 36 having a pitch P less than 30 °, or give to these orifices an oblong shape, offering an infinity of positions. In addition, it could provide another method of fixing certain devices, for example if a device has a frame straddling the rail and provided with a lateral tightening screw, with or without notches on the rail. Note also that the rail 34 could be discontinuous, that is to say include one or more sections in an arc in order to release certain spaces, for example for the passage of a functional connection between a display device and the control rod 16 or the calendar driving member of the basic movement 1.
    Each of the display devices 31, 32 comprises a frame here called carriage, that can be positioned by displacement along the rail 34. This carriage, fixed to the rail 34 by the screws 38 engaging in the screw feet 37 can be likened to a plate for the mechanical components that make up each display device 31, 32. It can be seen in FIGS. 2 and 3 that the carriage 41 of the hour / minute display 31 is provided with three shafts 42, 43 and 44 for use as pivot axes. Thus, the shaft 42 carries an upper roadway 45 provided with the minute hand M and a wheel 46. The shaft 43 receives a gun 47 equipped with the hour hand H and an upper hour wheel 48. Finally, the shaft 44 supports an upper clockwork wheel 49 connecting the pinion of the upper roadway 45 to the upper wheel 48 with the usual transmission ratio.
    The carriage 41 further comprises a bearing supporting the axis 51 (visible in FIG 3) of a double return 50, which connects the wheel 46 of the upper road 45 to a driving wheel 52 fixed on the floor 13 of the basic movement 1. Because the rail 34 and its row of orifices 36 are centered on the axis 2 of the output of the movement 1, the double return 50 is engaged with the wheel 52 in any of the possible positions of the display device 31 on the rail 34. Of course, the transmission ratio of the double return 50 is 1: 1, so that the needles M and H rotate at the same speed as the wheels 14 and 15 of the basic movement 1.
    The carriage 54 of the display device 32 carries a bridge 55. This bridge 55 and the carriage 54 are provided with two pairs of stones to support respectively a small second axis 56 and a return 58. As visible in the example of FIG. 2, the shaft 56 is equipped with a wheel 57 and the small second needle S while the gear 58 is engaged with the wheel 57. The gear 58 is also engaged with a fixed driving wheel 59 fixed at the top of the second axis 11 instead of the usual central second hand. Thus, as for the first display device 31, regardless of the position of the second display device 32 on the rail 34, the gear 58 remains geared to the wheel 59. Preferably, the wheels 57 and 59 have the same diameter so that they can rotate at the same speed.
    For cases where the display assembly 30 should comprise, in addition to the devices 31 and 32 described herein, other display devices which might require correction, for example a second time zone display, of calendar or moon phase, a central corrector wheel 62 is rotatably mounted on the floor 13 of the base movement 1 and wedged axially using a spring 63 (referenced in Fig. 3). It can be driven by the correction wheel 17 via the train of two corrector counters 18 and 64 mounted on the plate 10 of the basic movement 1. Thus, a display device requiring a correction function can be mounted no matter where along the rail 34, remaining in engagement with both the central corrector wheel 62 and with the wheel which normally drives this device, for example the hour wheel 15.
    It is found that the system combining the rail as an intermediate support with several display devices allows not only to place the displays of these devices in different positions, without changing the components, but also to replace a display device with a different device to diversify the range of products of the manufacturer. It may be a device displaying another size, but also a device displaying the same size, but in a different way, for example with a disk, a drum, a retrograde needle or even with a second needle for example, to display a fixed shift time zone.
    According to a second embodiment of the invention, an example of which is shown in FIGS. 5 to 7, the intermediate support of the display assembly is in the form of a frame 70 fixed to a fixed portion 10, here the plate, of the base movement 1 at least partially overlap. In the example illustrated in FIGS. 5 to 7, the frame 70 is in the form of a circular plate, with a central opening 71 facing the mechanical output of the base movement 1.
    Preferably, the movement 1 is the same as that of the first embodiment and it is also equipped with the same date display by means of the two-stage ring 20, the upper disk 22 carries the dates appearing in the window D shown in FIGS. 8 to 18.
    The elements of the time display assembly of the watch are mounted on the frame 70 or, preferably, between the frame 70 and at least one bridge 72. In the example illustrated in FIGS. 5 to 7, it is used a single bridge 72 substantially circular plate-shaped and the same diameter as the frame 70.
    Each bridge 72 and the frame 70 are positioned and, therefore, fixed together to a fixed portion 10, here the plate, by means of several screws 73 each passing successively a bridge hole 74, a tubular spacer (no shown) defining the spacing between each bridge 72 and the frame 70, and a hole 76 of the frame 70. Preferably, each screw 73 is held in the plate 10 by screwing into a threaded hole 77 of the plate 10. The locations of the holes 77 do not follow a particular distribution. Thus, they should rather be chosen according to the zones available on the fixed part 10 of the movement 1.
    According to the second embodiment, the frame 70 and the bridge 72 comprise several series of support members to mount the mechanical elements of the display assembly. In the example illustrated in FIGS. 5 to 7, the support members are formed by holes. These support members have a regular layout based on the example shown in FIG. 18, on six radial axes 81 to 86 and spaced apart from each other by an angular pitch P = 30 ° as for the first embodiment.
    According to this scheme, there is provided a ring of twelve pivoting holes 87 in the frame 70, on a relatively large diameter circle, and, in line with them, a crown of twelve larger holes. 88 in the bridge 72. The diameter of the holes 88 wider allows to receive different elements as needed, including a tree, or a cushion-type stopper or clockwork, as will be seen later.
    On a circle of smaller diameter, there is further provided a second series of six pivoting holes 89 in the frame 70 distributed substantially in a ring and, vertically, a second ring of six wider holes 90 in the bridge 72. Preferably, the second series of holes 89 is staggered of the first series of holes 87 and is closer to the output axis 2.
    Similarly on the bridge 72, the second series of holes 90 is staggered of the first set of holes 88 and is closer to the output axis 2. It is therefore understood that a wheel mounted to the Using one of the pairs of holes 89 and 90 can mesh with a mobile supported by one and / or the other of the two adjacent pairs of holes 87 and 88.
    As illustrated in FIGS. 5 and 7, the bridge 72 may also include a third ring-shaped series of six holes 91 each formed between two holes 88 and a fourth ring series of twelve holes 92, each being formed radially aligned with a hole 88 between the latter and the external edge of the bridge 72. The third and fourth series are intended to increase the modularity and / or add functionality to the display devices as explained below.
    The mechanical output of the basic movement 1 is more particularly visible in FIG. 6. The fixed part 10 is recognized, here the plate, the second axis 11 provided with the seconds wheel 12 and guided by means of a fixed tube 9, the roadway 13, the driving wheel 14 and the hour wheel 15 driven by the teeth 13a of the floor 13 via the usual timer train (not visible in the drawings). The roadway 13 used here replaces that of the original movement because it is shorter. Its upper end is provided with an upper drive wheel 94 of diameter small enough to take place in the central opening 71 of the frame 70. Above the wheel 94 is the second drive wheel 95, fixed at the end of the axis 11.
    The frame 70 and the bridge 72 bear two time display devices 111 and 112 driven by the output of the movement 1 described above. In the example illustrated in FIGS. 5 to 7, the first display device 111, of the "regulator" type, such as that 31 of the first embodiment, displays the time by the decentered needle H and the minute by the central hand M. This is carried by an upper roadway 96 provided with teeth 97 and pivoting on a shaft 98 fixed to the center of the bridge 72. The hour hand H is carried by the barrel of a wheel 100 which pivots on a shaft 101 mounted in the one of the holes 88 of the bridge 72, in this case the hole located in the direction of the top of the dial of the watch.
    The mobiles 100, 96 hours and minutes of the display device 111 are connected by a timer mobile 102 having a timer axis 103 rotatably mounted in a guide tube 104 driven into a hole 91 of the bridge 72. The axle 103 carries a timing gear 105 in engagement with the wheel 100, an upper plank 106 meshing with the toothing of the upper roadway 96, and a hub 107 secured to a lower plank 108 which is engaged with the wheel upper carriage 94 of the carriageway 13 of the basic movement 1. The two boards 106 and 108 are identical, to simplify manufacture, and form a double return playing the same role as the double return 50 of the first embodiment.
    Of course, the transmission ratio of the timer between the upper roadway 96 and the wheel 100 is preferably equal to 1:12. However, if it was desired that the hour hand H turn in 24 hours only, it would be sufficient to change the diameters of the wheel 100 and pinion 105.
    In the example illustrated in FIGS. 5 to 7, the second time display device 112 is of the small second type, with the second S needle decentered similarly to that 32 of the first embodiment. This needle S is carried by an axis 113. The latter is provided with a pinion 114 and is guided between a pad 115 (plug or stone) driven into one of the holes 88 of the bridge 72 and one of the holes 87 of the built 70.
    The pinion 114 of small second is connected to the drive wheel 95 via an intermediate wheel 116 whose axis 117 pivots in one of the holes 89 of the frame 70 and a pad 119 (plug or stone) chased into the one of the holes 90 of the bridge 72. The driving wheel 95 and the pinion 114 preferably have the same diameter, in order to rotate at the same speed.
    According to a preferred embodiment of the invention illustrated in FIG. 6, a magnet pin 118 is driven into one of the holes 92 in front of the pinion 114. The pin 118 advantageously makes it possible to act on the toothing of the pinion 114 in order to brake the latter when one of its teeth is at the plumb the pin 118 in order to reduce the oscillations of the needle S.
    Note that the two time display devices 111 and 112 respectively fulfill the same functions as the two display devices 31 and 32 of the first embodiment and may also each occupy twelve distinct positions, mutually offset by steps of 30 °, on the circumference of the dial of the watch. Simple solutions can still allow other positions. For example, in the second embodiment, in the bridge 72 and the frame 70, more or fewer holes 74, 76 may be provided in order to increase or decrease the number of fixing screws 73. For example, the game could then be shifted 15 degrees (0.5-P) or 45 degrees (1.5-P) from the first.
    The example illustrated in FIGS. 5-7 shows a relatively thin construction of a display assembly according to the invention. This low height is allowed in particular by the fact that here there is no provision for a corrector in the display assembly itself, but only the corrector of the basic movement 1. Nevertheless, the second embodiment could also be designed with a central corrector wheel such as the wheel 62 described above, to correct for example the indication of a second time zone or a calendar display supported by the frame 70 and the bridge 72.
    It will also be noted that the bridge 72 could be replaced by a different bridge cooperating with the same frame 70, depending on the needs, or even by several separate bridges, without resulting in a sharp increase in the number of blanks at the manufacturer. Likewise, the possible use of two frame designs as needed would not make much of the manufacturing and storage of parts, compared to the earlier solution of manufacturing and storing a plurality of complete display devices.
    To form a device displaying the hour, the minute and the second in the traditional manner with needles H, M, S coaxial in the center, that is to say the configuration of FIG. 8, a person skilled in the art will understand that in the second embodiment of the invention, the time display device 111 can easily be modified for this purpose. Referring to FIG. 6, it will be noted that, without modifying the timer wheel 102, the hour wheel 100 could be placed on a gun rotating around the roadway 96, remaining in engagement with the timer gear 105 thanks to the equidistance of the holes of the bridge 72. The central second needle S may be worn in the usual manner by an axis passing through the shaft 98 and coupled to the axis 11 of the base movement 1. If, on the contrary, the display device is retained 112 of small seconds, we obtain the configuration of fig. 9.
    Similarly, keeping the display device 112 at a small second, a conventional display device can be provided hour and minute off-center position on the shaft 101, without changing anything to the timer mobile 102 It is simply necessary to change the shaft 101 so that it serves as a pivot to a floor meshing with the board 106 and supporting around it the barrel of the hour wheel 100. This gives the configuration of the fig. . 10.
    Figs. 11 to 15 show schematically other time display configurations by hour hands H, minutes M and seconds S, which can be easily performed on the same base movement 1 using the present invention. It will be noted that the date window display D may or may not be present, and that the window D may be in many different positions, in particular to combine harmoniously with the various graduations associated with displays of the type, for example , needles H, M, S.
    As explained for the second embodiment above, it is important to note that all the configurations shown in FIGS. 8 to 18 may also be obtained using the principles of the first embodiment of the invention, namely display devices comprising carriages of the type 41, 54 which can be placed in various positions on a support rail of the type 34 at least partially circular, that is to say, annular or arcuate.
    Figs. 16-18 provide an overview of the very wide modularity of a watch display that can be offered by the present invention. As shown in fig. 18, when the angular pitch P is 30 ° in accordance with the two embodiments described above, it can be seen that a distribution along six main axes 81 to 86 is already possible with the same basic movement 1 of the current model .
    According to a second example illustrated in FIG. 16, with a conventional time display with H and M needles in the center and a small second S, the latter can occupy any of the twelve positions 120 corresponding to the axes 81 to 86, without any change of mechanical parts. Incidentally, the date window D can also occupy any position, such as, in particular, positioned permanently opposite the small second relative to the axis 2, if desired. In addition, the small second S at a position 120, it remains possible to place one or more additional display devices.
    In another example illustrated in FIG. 17, the display assembly includes an off-center display with the hands H and M. Therefore, the small second S can occupy up to seven different positions 121 along an arc centered on the axis 2 of the output basic movement 1 without any change of mechanical parts. Incidentally, the date window D can also occupy any position. In addition, by placing the small second S towards the most lateral positions 121, it may be envisaged to place an additional display device.
    In view of FIG. 18, it is immediately apparent that with an output of a conventional movement 1 and without any change of the mechanical parts, it is possible to obtain a lot of positioning with respect to the axes 81 to 86 to obtain original display configurations or at least unusual. Only the dial changes which brings an immediate economic benefit compared to the module modifications as currently done.
    In addition, advantageously according to the invention, it is also understood that for a given orientation of the display, the manufacturer can choose to place the control rod 16 and its crown 16a in twelve different directions without any modification of the basic movement 1 and the display assembly, that is to say without any change of mechanical parts.
    The foregoing description demonstrates that the present invention allows many different configurations of a time display or not with a very small set of parts. One skilled in the art will appreciate that the invention offers the same advantages for displays of other types driven from the basic movement, including chronograph, calendar, power reserve or moon phase displays. It also makes it easy to combine a basic movement of the current type with displays of special types, for example with retrograde hands, without transformation of the main mechanical components of the watch.
    In addition, in order to limit the number of blanks and according to a third embodiment, it would also be possible to use a thicker intermediate support such as a frame 70 'and simultaneously comprising for example the attributes of the frame 70 and of the bridge 72 of the second embodiment. An example of such a third embodiment is shown in FIGS. 19 and 20. According to this third embodiment, the pivoting of the mobiles are preferably made similarly to the timer mobile 102 of the second embodiment. Therefore, such a third embodiment no longer requires additional bridge.
    To better understand the example of Figs. 19 and 20, the references used are close to those of the corresponding elements of the second embodiment, in particular with respect to those of FIG. 7. Thus, one can distinguish the frame 70 'which can be fixed to a fixed portion 10 of the movement 1 by means of several screws passing through each, a hole 76' of the frame 70 '. According to the third embodiment, the frame 70 'has several series of support members for mounting the mechanical elements of the display assembly.
    In the example illustrated in FIGS. 19 and 20, the support members are formed by holes which have a regular arrangement based, from the example shown in FIG. 18, on six radial axes 81 to 86 and spaced apart from each other by an angular pitch P = 30 ° as for the first two embodiments.
    According to this scheme, there is provided a ring of twelve positioning holes 87 'in the lower part of the frame 70', which opens each to a wider hole 88 'of the upper part of the frame 70'. The holes 88 'thus also form a crown of twelve wider holes 88'. The diameters of the holes 87 ', 88' make it possible to receive different elements according to the needs as for the second embodiment.
    On a circle of smaller diameter, there is further provided a second series of twelve positioning holes 89 'in the lower part of the frame 70' also distributed substantially in a ring. In the example of FIG. 20, a recess 71 'is formed in the upper part of the frame 70'. The recess 71 'is intended to be mounted opposite the mechanical outlet and communicates tangentially with the holes 88'. It is understood that a mobile present in a hole 88 'can thus mesh with a mobile positioned in the recess 71' and in particular fixed in the hole 89 'facing said hole 88'.
    By way of example, as illustrated in FIGS. 19 and 20, an axis 113 'has been positioned in a hole 88' by fixing one of its ends in the corresponding hole 87 '. It has also been added a first 98 'and a second 101' shafts respectively fixed in a central hole of the upper part of the frame 70 'and in another hole 87' to show two pivot levels similarly to the second embodiment. Thus, the shaft 101 'has a foot 100' fixed in a hole 87 'to project the shaft 101' of the upper part of the frame 70 '. Finally, two guide tubes 104 'have been mounted in two separate holes 89'.
    Therefore, as for the first and second embodiments, the third embodiment through the holes 87 ', 88' and 89 'also allows a high degree of modularity and / or add functionality to the display devices as explained above.
    In addition, according to a variant of the invention and for the three embodiments, it is possible to envisage that a portion of the display assembly 30 is integral with the fixed portion 10 of the movement 1. It can thus be imagined that the intermediate portion 34, 70, 72 and / or 70 'of the display assembly 30 is completely or partially shaped with the fixed part 10 used to mount the display assembly 30 as, for example, the platen of the movement 1. In addition, the fixed portion 10 of the movement 1 can not be limited to its plate but can also be a bridge or even part of the drive mechanism of the calendar display.
    It should also be understood that, for the three embodiments advantageously according to the invention, the symmetry of the intermediate means 34, 70, 72, 70 'conjugated with that of the fixing holes 76, 76' also allows the modification of the positioning of the displays without modifying the mounting of the display devices 31, 32, 111, 112. Thus, all that is required is to remove the screws 35, 73 and then turn the display assembly 30 with respect to the clockwork movement 1 in order to to securely fasten the display assembly in a new position. Consequently, more threaded holes 77 can also be provided in the fixed part 10 of the clockwork movement 1 to allow more possible positions.
    Finally, the calendar element can not be limited to a date ring 20 with two annular disks 21 and 22 connected by pillars 23. It is only important to make a spacing relative to the plane of the drive mechanism. This spacing substantially corresponds to the thickness of the display unit 30 in order to present the display of said calendar at the nearest of said analog display, that is to say, in the case of FIGS. . 8 to 18, directly above the aperture D. Of course, this height compensation can also be applied to the modules mentioned in the background of the invention.
    Therefore, according to a first alternative of the invention, the date element may be a cylinder whose inner diameter comprises a set of teeth capable of meshing with said basic movement drive mechanism 1 and whose height extends according to said spacing. It is also possible to alleviate this alternative to hollow out part of the cylinder as shown in FIG. 21. It is thus possible to obtain a one-piece date ring 20 'for example by bar turning, by injection or by a MIM (Metal Injection Molding) process. The one-piece date ring 20 'comprises a substantially S-shaped section, has an upper portion 22' bearing the date scale and a lower portion 21 'having a toothing 24'. The lower portions 21 'and upper 22' may further be connected by a wall 23 'whole or partially hollow. It is therefore understood that the display disc 22 ', the spacing means 23' and the drive disc 21 'are monobloc.
    However, preferably, the date ring is formed by at least two separate parts as illustrated in FIGS. 22 to 36. Indeed, it is very advantageous to be able to keep the integrated disk of the basic movement 1 (drive disk) and to associate it with any kind of display using the interchangeable disk (display disc) of color, material and / or different height.
    Thus, during the production of the movement, it is common that the trim parts of a timepiece collection are modified as the display of the date D or the dial G. It may then become necessary to change the color of the background and / or the alphanumeric characters of the date. Advantageously, by using a two-part calendar display, it becomes very easy to swap the display disc without disassembling the drive disc.
    In addition, it is also possible to choose a different material for each disk. This advantageously allows to be able to manufacture the drive disk with a material or a metal alloy which ensures high reliability of meshing (drive, wear) with the movement 1 even with a small thickness. It is possible to associate a display disk formed from a lower density material than that of the drive disk, such as plastic, to reduce the overall inertia of the display of the calendar and / or allow the manufacture directly in the desired background color.
    Finally, as illustrated in FIG. 22, it also becomes easy to swap the display disk A with a thicker B without disassembling the drive disk C if a display module E or a display device E according to the invention is thicker that F mounted for another collection or previously, is mounted on a movement 1. Such a change avoids the phenomenon of wells, that is to say the impression that the display is at the bottom of a cavity opened by the window D, which is usual on the timepieces to which a module has been added as a small second by causing an extension of the dial G.
    Therefore, advantageously according to a second alternative of the invention illustrated in FIGS. 23 to 24, the calendar display 140 includes a drive disk 141 meshing with the movement 1 by means of teeth 144 and connected to a display disk 142 having said display by spacing means 143 to present the display D of the calendar closest to the analog display, that is to say the dial G, substantially compensating for the thickness of the display assembly 30 or a module cited in the background of the invention.
    As visible in FIGS. 23 and 24, the spacing means 143 form one-piece pillars with the display disc 142 and are connected to the drive disk 141 by means of fastening means 147 formed by hole 146 - pin 145 assemblies. illustrated in fig. 24, we see that the display disk 142 is very close to the dial G.
    Advantageously according to a third alternative of the invention illustrated in FIGS. 25 and 26, the calendar display 160 includes a drive disk 161 meshing with the movement 1 by means of a toothing 164 and connected to a display disk 162 having said display by spacing means 163 to present the display D of the calendar closest to the analog display, that is to say the dial G, substantially compensating for the thickness of the display assembly 30 or a module cited in the background of the invention.
    As visible in FIGS. 25 and 26, the spacing means 163 form a one-piece flange with the display disc 162 and are connected to the drive disk 161 by means of fixing means 167 formed by tenon assemblies 165 - mortise 166.
    Advantageously, according to a fourth alternative of the invention illustrated in FIGS. 27 and 28, the calendar display 180 comprises a drive disk 181 meshing with the movement 1 by means of a toothing 184 and connected to a display disk 182 having said display by spacing means 183 to present the display D of the calendar closest to the analog display, that is to say the dial G, substantially compensating for the thickness of the display assembly 30 or a module cited in the background of the invention.
    As visible in FIGS. 27 and 28, the spacing means 183 form a one-piece collar with the display disk 182 and are connected to the drive disc 181 by means of fixing means 187 formed by tenon assemblies 185 - mortise 186 as well as sets throats 188 - against throat 189.
    Advantageously according to a fifth alternative of the invention illustrated in FIGS. 29 and 30, the calendar display 200 comprises a drive disk 201 meshing with the movement 1 by means of a toothing 204 and connected to a display disk 202 having said display by spacing means 203 to present the display D of the calendar closest to the analog display, that is to say the dial G, substantially compensating the thickness of the display assembly 30 or a module cited in the background of the invention.
    As visible in FIGS. 29 and 30, the spacing means 203 form one-piece pillars with the display disc 202 and are connected to the drive disc 201 by means of fixing means 207 formed by bayonet assemblies. Each bayonet-type fastener has a double-sectioned hole 206 formed in the drive disc 201 and in which a double-section stud 205 is mounted at the end of the spacer means 203.
    Advantageously according to a sixth alternative of the invention illustrated in FIGS. 31 and 32, the calendar display 220 comprises a drive disk 221 meshing with the movement 1 by means of a toothing 224 and connected to a display disk 222 having said display by spacing means 223 to present the display D of the calendar closest to the analog display, that is to say the dial G, substantially compensating for the thickness of the display assembly 30 or a module cited in the background of the invention.
    As visible in FIGS. 31 and 32, the spacing means 223 form a one-piece collar with the display disk 222 and are connected to the drive disk 221 by means of fastening means 227 formed by bayonet assemblies. Each fastener bayonet type comprises a groove 226 double section formed in a flange of the drive disc 221 and in which fits a stud 225 mounted peripherally at the end of the spacing means 223.
    [0080] Advantageously according to a seventh alternative of the invention illustrated in FIGS. 33 and 34, the calendar display 240 comprises a drive disk 241 meshing with the movement 1 by means of a toothing 244 and connected to a display disk 242 having said display by spacing means 243 to present the display D of the calendar closest to the analog display, that is to say the dial G, substantially compensating for the thickness of the display assembly 30 or a module cited in the background of the invention.
    As visible in FIGS. 33 and 34, the spacing means 243 form a one-piece flange with the display disc 242 and are connected to the drive disc 241 by means of fastening means 247 formed by groove 246 - hook 245 assemblies. fixing type groove-hook comprises a groove 246 formed in a flange of the drive disc 241 and in which fits a hook 245 resiliently mounted in extension spacing means 243.
