    FIELD OF THE INVENTION
    The present invention relates to a so-called universal timepiece, the dial of which makes it possible to quickly read the time of different time zones. It relates more particularly to such a timepiece comprising a first dial bearing geographical indications corresponding to the different time zones and defining a 24-hour round, and comprising a second dial bearing a 24-hour hour round, the second dial being movable concentrically to the first dial and being arranged to be driven in rotation at the rate of one revolution in 24 hours by the movement of the timepiece, the time indications being arranged opposite the geographical indications of the first dial to indicate local times .
    PRIOR ART
    [0002] Universal timepieces corresponding to the above definition are known. The Swiss patent CH 270'085 in particular describes a universal watch which comprises a central fixed twelve-hour dial above which the hour, minute and second hands rotate in a conventional manner. A first twenty-four hour annular dial is rotatably mounted around the central dial. This annular dial is arranged to be driven by the movement, counterclockwise, at the rate of one revolution in twenty-four hours. It is still synchronized with the hands so that the transition from the 12 hour and 24 hour indications to the "twelve o'clock" position of the watch takes place at the instant when the hands are superimposed at twelve o'clock. A second annular dial, bearing geographical indications corresponding to the time zones, is rotatably mounted around the first annular dial. It is arranged to be moved manually by means of a crown whose stem ends in a conical pinion meshing with a peripheral toothing of the second annular dial.
    To know the time in a given place, the user of this watch of the prior art must use the crown to rotate the second annular dial and bring the name of the place where it is in position „ twelve hours“ of the watch. The two dials then make it possible to read the time corresponding to each of the time zones of the globe. Thus, as illustrated in this earlier document, when it is eight o'clock in the evening in New York, it is one o'clock in the morning in Paris, ten o'clock in Tokyo and six o'clock in Mexico City.
    [0004] A problem noted with this type of universal watch relates to the transition from winter time to summer time and vice versa. Indeed, because of this biannual time change, the time difference between two places is not always constant. On the contrary, when the time change does not take place at the same time in the two places considered, the seasonal time change is accompanied by variations in the time difference. This is usually the case, in particular, when the two places are, one in the northern hemisphere and the other in the southern hemisphere. Moreover, it is, of course, always the case when the country where one of the places is located does not practice daylight saving time, while the country of the other place does.
    [0005] Because of the aforementioned problem, the indications provided by most known universal watches are only accurate in certain standard situations, and are false in a certain number of atypical situations.
    BRIEF DESCRIPTION OF THE INVENTION
    An object of the present invention is to remedy the drawbacks of the aforementioned prior art. The present invention achieves this object by providing a universal timepiece in accordance with appended claim 1.

    DETAILED DESCRIPTION OF AN EMBODIMENT
    Figure 1 is a plan view from the dial side of a universal watch according to the invention. Figures 7 and 8 are two schematic exploded views showing the main elements of this same watch. By referring simultaneously to FIGS. 1, 7 and 8, it can be seen that the watch represented comprises a middle part 39 closed on the top by three dials. We first see a fixed annular dial 44 which carries a 12-hour hour circle, and which is arranged to cooperate with hour and minute hands respectively referenced 41 and 42. The annular dial 44 surrounds a first dial 3 formed by a dial support (or board) 9 which here has the shape of a disc and which carries mobile dial sectors (11 to 15). The first dial 3 is provided with geographical indications 5 which go around the dial and which correspond to the 24 time zones of the planet. On the other hand, the first dial carries a second central dial (referenced 7) arranged concentrically to the first dial. The second dial bears a 24-hour chapter ring intended to cooperate with the geographical indications of the first dial to indicate local times. The second dial 7 is arranged to be driven in rotation by the movement 46 of the watch in the counter-clockwise direction. Note that according to other embodiments, the second dial could just as well rotate in the same direction as the hands. In this case, the order of succession of the hours on the hour circle of dial 7 would also be reversed. The first dial 3 is arranged to be manually controlled in rotation by a manual control member operable from outside the caseband. This control member comprises a crown 53 secured to a pinion 55. The pinion 55 is arranged to mesh with a peripheral edge toothing 57 of the support 9. It will be understood that this arrangement allows the wearer of the watch to rotate the first dial 3, and therefore the geographical indications 5 that it bears, by operating the crown 53.
    We can still see in Figure 8 a programming disc 25 which is mounted under the support 9 of the first dial 3, coaxially with the latter. As will be seen in more detail below, the programming disk 25 forms part of the manual means which, according to the invention, are arranged to selectively shift some of the said geographical indications by 1/24 <th> of a turn. To this end, the watch of the illustrated example includes a dedicated control member in the form of a rotating crown 27 mounted at four o'clock in the caseband of the watch. Referring also to FIG. 3, it can be seen that crown 27 is integral in rotation with a pinion 29 arranged inside the watch case. The pinion 29 meshes with a peripheral toothing 31 of the programming disc 25. A jumper spring 51 (FIG. 6) is also arranged to secure the programming disc to the first dial 3. Note that the jumper 51 must not be too strong , so that, when the crown 27 is actuated, the disc 25 can rotate without driving the dial 3 with it.
    The caseband 39 is also arranged to receive the movement 46 of the watch. Conventionally, the movement of the watch comprises a roadway and a concentric hour barrel (not shown) which respectively carry the minute hands 42 and the hour hands 41. The movement 46 also comprises a 24-hour barrel concentric with the axis needles and which is arranged to drive the second dial 7 at the rate of one revolution in 24 hours. An opening 48 is also arranged in the caseband 39 to allow passage of the stem 47 for winding and for setting the time of the movement. This rod ends in a knurled crown 50 (FIG. 1).
    Figure 2 is an enlarged view of part of Figure 1, showing in particular the first and the second dial (respectively referenced 3 and 7). In this enlarged view, it can be seen that the mobile dial sectors 11, 12, 13, 14 and 15 bear some of the geographical indications 5, while other geographical indications are affixed directly to the plate 9 of the dial. On the other hand, plate 9 is pierced with a certain number of oblong openings 17 (better visible in figure 5) which define arcs of circles concentric with the dial. As will be seen in more detail below, the various sectors 11 to 15 are arranged to each slide in one of the oblong openings, so as to be able to shift angularly by a 1/24 <th> of a turn relative to the board of the first dial 3.
    [0012] The geographical indications 5 which are carried by the same mobile dial sector designate places where the passages between summer time and winter time take place on the same date in one direction as in the other. For example, it can be seen in FIG. 2 that the dial sector referenced 12 bears, from left to right, the geographical indications “Azores”, “London”, “Geneva” and “Helsinki”. You can check that the time change does indeed take place on the same dates in these four locations. Indeed, it has been decided that, until further notice, the transition to summer time will take place on the last Sunday of March, and the return to winter time will take place on the last Sunday of October. in this region of the world. It can also be seen in FIG. 2 that the dial sector referenced 11 bears, from left to right, the geographical indications “Anchorage”, “L.A.”, “Calgary”, “Chicago”, “N.Y.” and “Hallifax”. These six cities are all located in the United States or Canada, and in these regions, the changeover to daylight saving time currently occurs on the second Sunday of March, while the return to winter time occurs the first Sunday in November.
    In the illustrated embodiment, three other sliding sectors (referenced 13, 14 and 15) each bear a unique geographical indication. Each of these three geographical indications corresponds to a place in the southern hemisphere where, as is well known, the seasons are reversed with respect to the northern hemisphere. For example, in Sydney (dial sector 13) and South Australia, daylight saving time changes on the first Sunday in October, and standard time returns the first Sunday in April of the following year. In Auckland (dial sector 14) and the rest of New Zealand, summer time changes on the last Sunday in September, and standard time changes on the first Sunday. April of the following year. Finally in Rio de Janeiro, (dial sector 15), the transition to summer time takes place on the third Sunday of October, and the return to winter time takes place on the third or fourth Sunday of February of the following year.
    It can be seen in Figure 2 that the first annular dial 3 still bears, from left to right, the geographical indications "Abidjan", "Tripoli", "Pretoria", "Djibouti", "Moscow", "Karachi". , "Dhaka", "Bangkok", "Hong Kong", "Tokyo", "Brisbane", "Noumea", "Midway", "Samoa", "Hawaii", "Gambier Islands", "Henderson Islands", "Culiacan “, „Galapagos“, „Lima“, „Caracas“ and „Buenos Aires“. These latter geographical indications correspond to places where summer time is not practiced. As there is therefore no seasonal time change in these regions, the corresponding geographical indications do not need to be carried by moving dial sectors, and can therefore be carried directly on plate 9 of the first dial.
    [0015] Figure 5 is a view from the back side of the watch, the back and the movement having been removed so as to provide a bottom view of the plate 9 of the dial 3. As already mentioned in connection with Figures 1 and 2, plate 9 is pierced with a certain number of oblong openings 17 which define arcs of circles concentric with the dial. In the present example, these different arcs are not all subtended by the same circle. A first circle subtends four of them, while the fifth is on a larger diameter circle. We can also see in Figure 5 that the plate 9 also carries five small star mobiles (respectively referenced 19, 20, 21, 22, and 23) each formed of a four-pointed star and a small toothed wheel assembled in coaxial position. The five small star mobiles are rotatably mounted on the plate 9 and, as shown in FIG. 5, the distances separating them from the axis of the watch are all different in the present example.
    As mentioned above, the mobile dial sectors 11, 12, 13, 14 and 15 are arranged to slide in the arcuate openings 17. To this end, the mobile dial sectors include feet (not shown) which are inserted into the oblong openings so that the end of the feet comes out under the board of the first dial. FIG. 6 is a view similar to FIG. 5 further showing five toothed sectors (referenced respectively 11A, 12A, 13A, 14A and 15A). On the basis of Figure 6, it can be understood that the mobile dial sectors are each secured to one of the toothed sectors via the feet passing through the openings 17 in an arc of a circle (during assembly of the part of watchmaking, one can for example proceed by first inserting the feet into the openings of the board, and then driving the distal end of each foot into a hole provided for this purpose in one of the toothed sectors). As can still be seen in FIG. 6, each of the toothed sectors 11A, 12A, 13A, 14A and 15A meshes with the teeth of one of the small star mobiles (respectively 19, 20, 21, 22 and 23). Thus, a rotation of one of the small star mobiles will have the effect of causing the corresponding dial sector to slide in one of the openings of the plate of the first dial. Finally, FIG. 6 still shows five jumper springs 49 which are arranged to cooperate with the five mobile dial sectors. It will be understood that thanks, on the one hand, to the limited length of the circular arc openings 17, and on the other hand, to the presence of the jumpers 49, the mobile dial sectors 11 to 18 can each occupy only two positions. which are separated from each other by 1/24<th>of a turn.
    Figure 3 is a view similar to those of Figures 5 and 6, but in which there is also shown a programming disk 25 whose function is to determine the order in which the various movable dial sectors 11, 12, 13, 14 and 15 are activated. In this view from the back side of the watch, the programming disk almost entirely masks the plate 9 of the first dial, of which only the peripheral toothing 57 is visible. It will also be understood that the toothed sectors 11A, 12A, 13A, 14A and 15A and the small star mobiles 19, 20, 21, 22 and 23 which are arranged between the programming disc 25 and the board 9 are not visible either. in FIG. 3. It can be seen, however, that the programming disc has ten pins referenced 19H, 19E, 20H, 20E, 21E, 21H, 22E, 22H, 23E and 23H. It should be noted that the lugs are arranged on the side of the programming disc 25 facing the plate 9, and that they are therefore not strictly speaking visible in FIG. 3. However, in the present example, the lugs are driven into holes in the programming disc. It is in fact the holes in which the lugs are driven which are visible in figure 3.
    It can be seen in Figure 3 that the crown 27 is integral in rotation with a pinion 29 arranged inside the watch case. The pinion 29 meshes with a peripheral toothing 31 of the programming disc 25. In the present example the programming disc is designed to rotate in the same direction as the hands of the watch when it is activated. Means known to those skilled in the art (not shown) are preferably also provided to prevent the rotation of the programming disc in the counter-clockwise direction. It will be understood, however, that the invention is not limited to the case where the programming disc must be operated in the direction of the hands of the watch. On the contrary, according to other embodiments, the programming disc could be arranged to rotate counter-clockwise when actuated. In this case, the lugs would be arranged in a different configuration on the disc.
    As can be seen in Figure 3, in the example shown, the respective distances separating the ten lugs from the axis of the watch are all different. Moreover, these distances go increasing in the order of lugs 19H, 19E, 20H, 20E, 21E, 21H, 22E, 22H, 23E and, finally, 23H. When the wearer of the watch rotates the programming disc 25 by actuating the control member 27, each of the lugs carried by the disc move along a circular path whose radius is equal to the distance separating this lug from the axis watch hands. It has already been noted above that the distances separating the five star mobiles from the axis of the watch were also all different. Indeed, each star mobile is arranged in such a way that its star intercepts the trajectory of two very specific lugs. Thus, the star-shaped mobile 19 is arranged to intercept the circular trajectories of the pins 19H and 19E, the star-shaped mobile 20 is arranged to intercept the trajectories of the pins 20H and 20E, and so on.
    [0020] The lug 19H is located slightly closer to the axis of the hands of the watch than is the axis of the star wheel 19. Thus, it will be understood that, when the lug 19H rotates and it encounters the star wheel 19, he rotates it a quarter turn in the opposite direction to the direction of rotation of the programming disc. Conversely, the lug 19E is located slightly further from the axis of the hands of the watch than the star wheel 19 is. Thus, when the lug 19E meets the wheel star 19, it makes it turn the same direction as the program disc. Moreover, as can still be seen in FIG. 2, the toothing of the toothed sector 11A is an internal toothing (in other words, turned in the direction of the axis of the needles). Under these conditions, it will be understood that, when the star-shaped mobile 19 drives the toothed sector 11A, the latter rotates in the same direction as the star-shaped mobile. Under these conditions, when the lug 19E meets the star of the mobile 19, and the latter therefore performs a rotation of a quarter turn clockwise, this rotation has the effect of sliding the mobile dial sector 11, also clockwise. This amounts to saying that the lug 19E causes the moving dial sector 11 to switch to summer time. Regarding ergot 19H, it is the opposite. Indeed, as we have seen, the pin 19H rotates the star wheel 19 in the opposite direction. Thus, it will be understood that the lug 19H is arranged to cause the mobile dial sector 11 to return to winter time when it encounters the starry mobile.
    Referring again to Figures 3 and 5, it can still be observed that the lugs are arranged on the programming disc 25 in such a way that each meeting of one of the lugs with a star wheel corresponds to a different angular position of the program disc. Moreover, the relation between the position of the lugs and that of the star mobiles is such that the lugs intervene in the order 23H, 19E, 20E, 21H, 22H, 22E, 21E, 23E, 20H and, finally, 19H, when the programming disc rotates clockwise. It should be noted that the manual means which have just been described make it possible to correctly control the outward and return changes between winter time and summer time even if the dates of its changes vary from one year to another. , provided that the succession of time changes in the different places indicated on the watch always maintains the same order. Note however that, if a political decision were to alter this order of succession of time changes, it would suffice to change the programming wheel 25 to adapt the watch to the new situation.
