Definitions

  • the invention relates to a universal timepiece, that is to say capable of displaying the time in different time zones, and more particularly a wristwatch known as a universal watch.
  • This timepiece includes at least one hour indicator intended to perform a revolution in twelve hours and a minute indicator intended to perform a revolution in one hour, as well as a movement conventionally driving the minute indicator and the 'hour indicator, and a rotating member indicating at least two time zones and manually rotatable.
  • the hour and minute indicators can be made up of hands or discs.
  • Watches are already known whose strap bears inscriptions indicating the time difference between different places on the planet. Thanks to these indications, the user of such a watch, by actuating his crown, can bring the hands to the position corresponding to the time of any of the time zones.
  • patent application EP 0 461 547 describes an indicator of time zones usable with such a watch. This indicator consists of a set of interchangeable passers-by each carrying a geographical indication corresponding to one of the twenty-four time zones and intended to be worn selectively on the watch strap to indicate on which time zone the latter is set. .
  • a particularly simple universal watch like this has flaws. Indeed the change hour, performed using the time setting crown, is a relatively laborious operation. The user must not forget the initial time at which he started the manipulation, and moreover, in order not to lose the exact hour he must estimate how much the minute hand moved during this manipulation.
  • Patent DE 1 673 621 describes a watch the movement of which includes a planetary train connecting the minute hand to the hour hand. The positioning of the hour hand can be carried out by rotating a cage carrying the planetary wheel of this cog by means of a pusher and a snap.
  • This type of universal watch also has faults. In fact, making time changes without moving the minute hand can give the user the impression of a retracted time interval.
  • the modifications which must be made to this movement are relatively numerous and delicate.
  • the object of the present invention is to provide a timepiece or universal watch in which the indicators, in particular the hands, can, by a very simple operation, be brought into a position corresponding to the time of any time. time zone, this timepiece can also be easily produced from a classic and ordinary timepiece movement.
  • the timepiece according to the invention is characterized in that it comprises an auxiliary gear train located outside the movement cage, this gear train being composed of a carriageway, a wheel hours and a timer and in that the timer mobile is mounted on a support rotatably mounted around the axis of rotation of the indicators and kinematically linked to said rotating member so that the drive in rotation of the member Turning the time zone indicator causes the hour indicator and the minute indicator to rotate through the timer.
  • the rotary drive of the time zone indicator rotating member which will generally take the form of a rotating bezel, therefore has the effect of rotating the hour and minute indicators in the same manner as in '' a conventional time setting.
  • the time zone change could be done by a rotation of any angle of the rotating bezel but in practice, the watch will generally be equipped with a rotating bezel capable of occupying twenty-four positions corresponding to the twenty-four time zones, this rotating bezel making one complete revolution for two turns of the hour indicator.
  • this rotating bezel makes a half-turn
  • the hour indicator makes one turn
  • the rotary timer holder makes one turn and an eleventh turn.
  • the watch movement can be a mechanical movement, automatic or not, as well as an electronic movement.
  • the time is set in a conventional manner by means of the winding crown.
  • Figure 1 is a top view of a watch according to the invention.
  • Figure 2 is a sectional view along 3H - 9H of the watch shown in Figure 1, but in which the minute and hour hands have been brought back into the plane of the drawing for a better understanding thereof.
  • Figure 3 is a top view of an alternative embodiment.
  • the watch shown in Figure 1, identified by the general reference 1, includes a box 2 housing a dial 4 in front of which rotates an hour hand 6 and a minute hand 7 around a geometric axis of rotation X ( Figure 2) .
  • the dial 4 carries time indications of a conventional type and is protected by a lens 8 which is kept fixed in the notch of a middle part of the bezel 10.
  • the watch 1 further comprises a time indicator timetable consisting of a rotating bezel 12 whose circumference carries twenty-four graduations such that the graduation 13 and twenty-four geographical indications 14 corresponding to the twenty-four time zones.
  • the position of the rotating bezel 12 can be identified using a fixed index 5 affixed to the dial or to the crystal.
  • the geographical indications are arranged in an order such that when one traverses the periphery of the rotating bezel 12 clockwise, one moves around the earth from West to East. It will naturally be possible to make a watch on which the geographical indications are arranged in reverse order.
  • the watch is furthermore provided with a usual winding crown 15.
  • the middle part of the bezel 10 is itself surrounded by an annular middle part 16, the rotating bezel 12 being retained between this outer annular middle part 16 and a range of the middle bezel 10.
  • the rotating bezel 12 can occupy twenty-four positions in which it is held by a snap consisting of a vertical pawl 17 mounted in the annular middle part 16 and pushed by a spring 18, this pawl 17 cooperating with twenty-four recesses 19 of the rotating bezel 12.
  • On the middle 16 is fixed a case back 19.
  • the watch is equipped with a movement 20, for example a mechanical movement.
  • This movement 20 is distinguished from a standard movement only by the fact that its pavement 35 is shortened, and has a toothing 36 or a dog clutch at its upper end.
  • the watch is on the other hand equipped with an auxiliary gear train mounted outside the movement cage, gear train consisting of an auxiliary carriage 22 rotatably mounted on a pin 21 fixed to the pinion center (not shown), a timer wheel 23 with its timer pinion 24 and an hour wheel with its barrel 25a located between the movement cage and the dial 4.
  • the lower end of the auxiliary road 21 is provided with a toothing or other dog clutch engaging the toothing 36 of the main carriageway 35 so that the two carriageways are integral in rotation.
  • the dowel 26, on which the timer mobile 23/24 is mounted is fixed on a support 27 rotatably mounted in the box around the axis X.
  • This support 27 is in the form of a circular part provided a toothed ring 28 and having a recess 29 in which the mobiles 22 to 25 are housed. This recess is closed by a plate 30 fixed on the rotary support 27.
  • This support 27 is itself rotatably supported by a fixed ring 31 supporting the dial 4.
  • the toothed crown 28 is engaged with a first reference 32 itself engaged with a second reference 33, identical to the reference 32, these two references being pivoted on the fixed ring 31.
  • the reference 33 is itself even in engagement with a radial toothing 34 formed on the inner side of the rotating bezel 12.
  • the toothing 34 has one hundred and forty-four teeth and the toothed crown 28 sixty-six teeth.
  • a rotation of the rotating bezel 12 thus has the effect of driving the timer 23/24 in rotation around the pin 26 and around the axis X.
  • the kinematic connection between the rotating bezel 12 and the support 27 is such that when the rotating bezel 12 makes one turn, the rotary support 27 makes two turns and two elevenths of a turn and the hour hand makes two turns. If one refers to a revolution of the dial of the hour hand, that is to say twelve hours, which corresponds to a half-revolution of the rotating bezel 12, the rotary support 27 performs one revolution and an eleventh turn. It should be noted that the hour hand is driven via the timer and that the minute hand turns normally as when setting a conventional time.
  • the time setting is carried out in a conventional manner by means of the winding crown 15. It can be seen that the timer pinion and the hour wheel of the standard movement could be omitted since the driving of the hour hand s 'performed by the auxiliary timer 25, which would reduce the thickness of the movement 20.
  • FIG. 3 represents an alternative embodiment in which the geographical indications 66 corresponding to the different time zones are affixed to the crystal 8, the rotating bezel 12 being simply provided with two indices 68, 69 located fifteen degrees from one of the other, index 69 corresponding to summer time and index 68 to winter time.
  • the watch is set to Paris summer time, as is the case in FIG. 3, we switch to Paris winter time by simply rotating the bezel 12 so as to bring the index 68 in front of the indication "Paris".
