Abstract

The watch comprises a 24 hour circle (8) located opposite a rotating bezel (6) itself divided into 24 areas numbered from 0 to 23. The numerals 0 to 23 refer to a list of time zones carried by the links (22) of the strap. The central part of each link carries the indication of geographical names of the time zones flanked, on the left, by a scale (23) for Winter times, that is to say for civil times and, on the right, by a scale (24) for Summer times. The wearer of the watch can thus, at any moment, ascertain the time in any time zone. An additional hour hand (12) can be moved step by step, one hour per step, with the aid of an operating button (13), thus making it possible, together with the ordinary hour hand (2), to display the time in two different time zones simultaneously. <IMAGE>

   4. Universal wristwatch according to claim 1, characterized in that it comprises an overtime hand, driven by the movement, capable of being moved manually step by step for the value of one hour per step, this overtime hand being carried by an overtime barrel wheel, coaxial with the ordinary hour barrel wheel.



   5. Universal wristwatch according to claim 4, characterized in that the connection between the two hour barrel wheels is ensured by at least one jumper articulated on one of them and which cooperates with a worn star wheel by the other, the two cannon wheels rotating at the same speed.



   6. Universal wristwatch according to claim 4, characterized in that the connection between the two hour cannon wheels is ensured, with reduction, by a satellite pinion, carried by one of them, engaged simultaneously with a pinion carried by the other wheel and with an internal toothing that has a crown, fixed in operation, coaxial with said hour barrel wheels.



   7. Universal wristwatch according to claim 6, characterized by the fact that said crown has, externally, a wolf tooth toothing with which cooperates a control rocker which can be actuated manually, making it possible to rotate said crown step by step, rotatably mounted on the movement frame, in order to produce the stepwise movements of the overtime hand.



   8. Universal wristwatch according to claim 4, characterized in that its ordinary hour wheel, making one revolution per 12 hours, drives; by means of a reference, at the rate of one revolution per 24 hours, a wheel which is coaxial with it and which is connected to the cannon wheel for overtime, the connection between the wheel making one revolution per 24 hours and the cannon wheel for overtime being provided by at least one jumper articulated on one of them and which cooperates with a star wheel of 24 teeth carried by the other.



   The subject of the present invention is a universal wristwatch comprising two concentric annular scales subdivided into 24 zones, one of which, rotatably mounted, can be operated manually, one of these scales being provided with 24 digits corresponding to a 24-hour revolution and the other of 24 signs indicating, in a coded manner, the 24 time zones, the bracelet carrying a correlation table between the time zones and said signs.



   Wristwatches of this type already exist, such as that described and represented in the brief CH-5990/66, which has the advantage of avoiding either that the 24 time zones have to be provided with the indication of geographical names of these, which is cumbersome or difficult to decipher, whether the user of the watch has to memorize the correlation code between the signs (numbers or letters of the alphabet) representing the time zones.



   However, the generalization of the adoption of summer time different from winter time requires, with known correlation tables, to make a correction to know summer time.



   The object of the present invention is to eliminate this drawback.



   This object is achieved by the means defined in claim 1.



   The drawing shows, by way of example, an embodiment of the subject of the invention and variants.



   Fig. 1 is a plan view of a universal wristwatch.



   Fig. 2 is a plan view of a detail of this watch on a larger scale.



   Fig. 3 is a plan view of a detail of a mechanism of this watch, on an even larger scale.



   Fig. 4 is a section along the broken line IV-IV of FIG. 3.



   Fig. 5 is a plan view corresponding to that of FIG. 3 of a variant of the mechanism shown in FIGS. 3 and 4.



   Fig. 6 is a section along the broken line VI-VI of FIG. 5.



   Fig. 7 is a plan view similar to those of FIGS. 3 and 5 of a second variant of this same mechanism, and
 Fig. 8 is a section along the broken line VIII-VIII of FIG. 7.



   The universal wristwatch shown, generally designated by 1, comprises three ordinary hands, hours 2, minutes 3 and seconds 4, rotating opposite a dial 5 comprising a 12-hour turn. The dates also appear in a window 6 on this dial. Setting the time as well as resetting the date, as well as winding in the case of a mechanical watch, are ensured by a control crown 7 which can occupy several axial positions.



   Watch 1 has a scale 8 subdivided into 24 zones numbered from 1 to 24, forming a 24-hour lap, part of which is dyed dark 9 to indicate the hours of the night while the rest indicates the hours of the day.



  It also includes a rotating bezel 10, knurled at 11, which allows it to be actuated manually, subdivided into 24 zones, corresponding to the 24 time zones, number téesde0 to 23.

 

   Finally watch 1 includes an additional 12 hour hand rotating at the rate of one revolution per 12 hours, like the hour hand 2, and which can be moved manually, step by step, at the rate of one hour per step, by means of a control button 13.



   The mechanism for driving the additional hour hand 12 is shown in Figs 3 and 4.



   This hand is carried by an additional barrel wheel 14 engaged on the ordinary barrel wheel, designated by 15, carrying the hour hand 2, and which carries, articulated on it at 16, two jumpers 17 subjected to the action of return springs not shown which tend to keep them engaged in a star wheel 18, with 12 teeth, driven out on the barrel of the hour wheel 15. Thus, thanks to this arrangement, in normal operation of the watch, the wheel with canon of hours



  additional 14 and its hand 12 rotate at the same time as the ordinary hour wheel 15 and its hand-needle 2.



   The movement plate, designated by 19 (fig. 4), carries a rocker 20, actuable by means of the pusher 13, which, when operated, performs a combined movement of translation and rotation, in the direction of the arrow 21 of fig. 3, causing its beak, designated by 20a, to cooperate with a wolf tooth toothing 14a, which has the wheel 14. The toothing 14a is sufficiently fine so that, whatever the angular position occupied by the wheel 14 when the pusher 13 is actuated, the rocker 20 produces a displacement of the wheel 14 sufficient to cause the jumpers 17 to cross the tip of one of the teeth of the star wheel 18, whereby the rotation of a step of the wheel 14 is completed by the pressure exerted by the jumpers on the wheel 18.



   As for the strap of the watch described and shown, formed of two strands, it is constituted by transverse links 22, articulated to each other. The correlation table between the numbers of the rotating bezel 10 and the time zones is carried by the two strands of the bracelet.



  The links 22 carry, in their central part, the geographical names of places corresponding to the 24 time zones, flanked, on the right and on the left, numbers which designate them, one of the scales, that on the left, designated by 23, corresponding in winter hours, that is to say the legal hours, while that on the right, designated by 24, corresponds to summer hours, that is to say a time most often offset by 60 minutes compared to winter time. Since not all countries use daylight saving time, it turns out that the same number can apply to more than one time zone for the 24 scale. Thus the time zones of the Azores and Dakar are both designated by the number 23 in summer while in winter that of the Azores is designated by 22 and that of Dakar by 23.

  The same is true of the Denver and Mexico time zones, both designated by 18 in summer and, respectively, by 17 and 18 in winter, those of
New York and Buenos Aires, both designated by 20 in winter and by 19 and 20, respectively, in summer, and others still.



   The watch user will set the watch so that it indicates the time of the place where it is located (local time). If he wishes to know the corresponding time in other time zones, he brings the figure corresponding to the time zone of the place where he is, by rotation of the rotating bezel 10, opposite the figure corresponding to the local time of the 24-hour turn 8. He can then read the time in that time zone, indicated by the 24-hour turn 8, next to the number in any time zone, also knowing it is day or night. thanks to the dark area 9.

  The user can also, at this time, by actuating the push-button 13, bring the overtime hand 12 opposite the figure corresponding to the time zone which interests him and, from this moment, the hand 12 will permanently indicate l time in this time zone while hand 2 will continue to indicate local time.



   Thus, this watch allows, in any place of the globe, to know, according to the local time, and this in a very simple way, what are all the others in the 23 other time zones, as it allows '' display the time in two different time zones at all times.



   The variant of FIGS. 5 and 6 differs from the first embodiment by the fact that the additional hour barrel wheel, designated by 25, carrying an additional hour hand 26 carries, rotatably mounted on it using '' a journal 27, a satellite pinion 29 engaged simultaneously with a planetary pinion 29 driven on the ordinary hour canon wheel, designated by 30, carrying the ordinary hour hand, designated by 31, and with the internal toothing 32a d a crown 32 coaxial with the wheels 25 and 30, carried by the plate, designated by 33.

  The crown 32 being fixed during the normal running of the watch, the mechanism described above ensures the connection between the two cannon wheels of hours 25 and 30 with gear reduction, so that, if the wheel 30 carrying the hand of the ordinary hours 31 makes one revolution per 12 hours, the overtime wheel 25 carrying the hand 26 makes one revolution per 24 hours.



   The manually operable control mechanism for the stepping movements of the needle 26 comprises a rocker 34 identical to the rocker 20 of the embodiment of FIGS. 3 and 4, which cooperates with a tooth with wolf teeth 32b, 12 teeth, which the crown 32 has. The latter being, as mentioned previously, fixed when the watch is running, there is no need for the teeth 32b to have to be fine as is the case with the toothing 23 of the wheel 14 of the first embodiment.



   Finally, in the control mechanism of the variant of FIGS. 7 and 8, the ordinary hour barrel wheel, designated by 35, drives, by means of a mobile formed by a wheel 36 and a pinion 37 , with gear reduction, a wheel 38 which is coaxial with it. If the 35-hour cannon wheel bearing the ordinary hour hand, designated by 39, makes one revolution in 12 hours, the wheel 38 will make one revolution in 24 hours.

 

  The overtime hand, designated by 40, is carried by an overtime cannon wheel 41 engaged on the barrel of the wheel 35. This wheel 41 is connected to the wheel 38 by a jumper mechanism 42 and toothed wheel in star 43 analogous to the corresponding mechanism of the embodiment of figs 3 and 4, with the difference that the star wheel 43 is 24 teeth while the star wheel 18 of the first embodiment is 12 teeth . The manual control of the step-by-step movements of the needle 12 comprises a rocker 42 identical to the rocker 20 of the first embodiment cooperating with toothed wolf teeth 41a, with fine teeth, of the barrel of the overtime 41.
