Definitions

  • the present invention relates to a timepiece with universal time display.
  • Patent is known CH 690.205 and EP 1,058,166 timepieces with a universal time display comprising, around the dial, a 24-hour rotating disc bearing a number from 1 to 24 and a rotating disc of the cities bearing the names of 24 cities corresponding to the 24 time zones.
  • Hour and minute hands cooperate with a fixed scale on the dial to display the local time in the time zone of the city whose name on the city disc is located at noon.
  • the 24-hour disk is kinematically connected to the hour and minute hands and rotates at the rate of one revolution per 24 hours in a counter-clockwise direction.
  • the local time in each time zone is indicated by the 24-hour disk number next to the city name of the time zone on the city disk.
  • the manual actuation of a pushbutton makes it possible to change the time zone.
  • Each press of the pusher activates a correction mechanism that moves the disc of the cities and the 24-hour disc one twenty-fourth of a turn counter-clockwise and the hour hand a twelfth of a turn in the
  • the hour hand is carried by a star hours which, in normal operation, is secured to the wheel hours of movement by a jumper.
  • the correction mechanism each time it is actuated by the pusher, moves the star of hours against the action of the jumper independently of the hour wheel and thus the roadway carrying the needle of the hours. minutes.
  • a disadvantage of such a mechanism is that the movement of the star hours requires overcoming the force of the jumper, which creates parasitic couples in the rest of the movement, likely to disrupt its operation.
  • a Another disadvantage is that this mechanism prohibits the possibility of correcting the hours in both directions, partly because it is not designed for this purpose, and secondly because the parasitic moments generated by the jumper when a correction in the counter-clockwise direction would have the effect of slowing or even stopping the movement.
  • the carrier and the satellite thus form a differential mechanism for suppressing parasitic couples in the drive mechanism when actuating the correction mechanism and for making time zone changes in both directions.
  • the planet carrier drives the first rotational member upon actuation of the correction mechanism, a simple construction of the timepiece according to the invention can be obtained.
