  • the screws 46 and pillars 47 of each pair are located at the two ends of each motor.
  • This module is fixed to the plate 39 by means of screws 48 taking in barrels 49, forming spacers, driven into the plate 39.
  • the microprocessor 25 is also carried by the plate 44 of the integrated circuit 45 (fig. 4), as does the liquid crystal cell (LCD) 10. This is fixed to the plate 44 of the integrated circuit with the interposition of two contactors Zebra 50, forming spacers, by means of a retaining flange 51.
  • FIG. 4 a shows that the flange 51 is fixed to the plate 39 using screws 52.
  • the Zebra contactors consist of parallelepipedal blocks of insulating material having metallized annular strips constituting conductive tracks.
  • the Zebra contactors 50 are in contact with the internal face of the liquid crystal cell 10 and with the internal face of the integrated circuit plate 44, ensuring the electrical connection between these two elements.
  • the information is entered into the microprocessor 25 using the rotating bezel 19.
  • the latter carries, on its external face, a thin annular disc 53 (fig. 5) housed inside a outer flange 19a of the bezel, in which it is crimped, and having a peg 54, driven in said bezel, ensures the angular orientation.
  • This annular disc 53 is divided into two concentric zones 55, themselves divided into segments corresponding to time zones (fig. 1), which are provided with geographical indications 56 which make it possible to identify them
  • the rotating bezel 19 carries, on its internal face turned towards the middle part 14 of the case, a ring 57 whose internal face has bosses 57 a (figs. 5 and 6) alternating with recesses 58.
  • This ring 57 has studs 57 b engaged in corresponding housings of the telescope 19, which ensures its orientation.
  • the middle part 14 carries a sleeve 59 in which is housed a pusher 60, carrying a seal (O-ring) 61.
  • This pusher is movable in the sleeve 59 and moves perpendicular to the plane of movement.
  • a return spring 62 keeps the pusher 60 in contact with the ring 57.
  • This coil spring bears on a ring 63 crimped at the end of the sleeve 59.
  • the internal end of the pusher 60 carries a ring 64 on which is stuck a ring 65 of conductive rubber intended to cooperate, when the pusher 60 is moved by the bosses 57 a of the ring 57, with a pair of contact blades 66 (figs. 2 and 5) in connection with the microprocessor 25 (fig. 11).
  • the middle part 14 carries a second contactor device identical to that described above and shown in FIG. 5, diametrically opposite to the first, with a slight offset, the head of the pusher, designated by 67, is visible in Figs. 6 to 10.
  • the number of bosses 57 a of the ring 57 carried by the rotating bezel 19 is even so that, when this ring is in the rest position, one of the pushers 60 and 67 is disposed on one side of a boss 57 a and the other on the other side of the boss 57 a opposite.
  • This arrangement is schematically illustrated in FIG. 6 where the ring 57 is partially shown in the developed state.
  • the pushers 60 and 67 not only ensure the short-circuiting and the breaking of the short-circuiting of the pairs of contacts 66 and 69, respectively, but also play the role of jumpers ensuring the stability (indexing) of the stop positions. of the rotating bezel 19.
  • the two pushers are shown separated from each other by a distance corresponding to the width of a single boss 57a of the ring 57, while they are diametrically opposed with a slight shift, this for the clarity of the presentation.
  • the two pushers can be placed in any relative position, provided that they are separated by a distance which corresponds to a multiple of the pitch of the scalloped part of the ring 57 a , plus a slight offset corresponding to the width of two half-pushers, that is to say one pushbutton.
  • the arrangement will be such that it is only once the complete cycle of the operations illustrated in FIGS has been carried out. 7 to 10 that the microprocessor will be able to accomplish the function dictated to him. Thus, false manipulations interrupted during execution, for example, will have no effect.
  • Fig. 11 schematically illustrates the connections between the microprocessor 25 and the pairs of contact blades 66 and 69, between the microprocessor and the motors 27, 28, 29 and 30, between the microprocessor and the liquid crystal cell 10 by the via a multiple decoder 71 and, finally, between the time setting crown 9 and the microprocessor via a block of contactors 72.
  • the angular position of the bezel 19 determines, via the microprocessor 25 and the motor 27, the position of the 12-hour hand 4.
  • the arrangement is such that by turning the bezel 19 and its disc 53 so as to bring one of the 24 time zone indications 56 opposite the point corresponding to 12 o'clock in the hour circle 7, the hand 4 is automatically brought to the position which designates the time in said time zone .
  • the ring 57 has 24 protrusions 57a corresponding to the 24 time zones.
  • the rotation of the telescope in the direction of the arrows 70 causes the sending of control pulses corresponding to the sequence below to the microprocessor 25: contacts 66 contacts 69 resting state 0 0 state 1 0 1 state 2 1 1 state 3 1 0 resting state 0 0
  • the microprocessor 25 is programmed so that each such sequence causes pulses to be sent to the motor 27 which advance the hand 4 by one hour.
  • the microprocessor 25 is programmed so that each such sequence causes pulses to be sent to the motor 27 which cause the needle 4 to go back one hour.
  • the new date will be displayed by the digital display device 10.
  • the bezel 19 carries on its disc 53, in addition to the indication corresponding to the watch mode (for example, LOCAL TIME), several indications corresponding to the different operating modes in chronograph (for example, SPLIT, LAP, RESTART , DOWN, DELTA, REGATE, RALLY).
  • the number of bosses 57a is then equal to the total number of operating modes of the part (ie 8 in the example given).
  • the mode is selected by rotating the bezel.
  • Each pulse sequence thus produced to bring an indication of the disc 53 opposite the point corresponding to 12 hours of the hour turn 7 switches the watch to the operating mode corresponding to the adjacent indication of the disc 53, either on the left, either to the right, depending on the direction of rotation.
