Definitions

  • the invention relates to a timepiece according to the preamble of claim 1.
  • Prior art :
  • Wrist or pocket watches which are designed mechanically, usually obtain the energy required for operation from a spring, which must be stretched or pulled up at regular intervals. If this is not done, the clock will stop and it must be reset if necessary. This is particularly associated with great effort when the clock is still connected to other elements, such as a calendar, moon phases or the like.
  • the clock can usually be adjusted by pulling out the crown and the hands to - once the clock has stopped - again set the correct time of day.
  • crowned crowns are also used to set the moon phase, day of the week and month for more complicated clocks.

  • Actuator plunger towards the housing interior spring beaufschlagbar Key head and actuating plunger are axially displaceable against each other against a spring force.
  • the actuating plunger is blocked in its housing outer position by a housing-fixed locking element. With the housing closer to the position of the key top, the locking element is movable by the key top into a position which lifts the blocking of the actuating tappet.
  • DE-OS-39 36 942 the described axial movement is thus the pusher stroke in order to trigger the switching functions can.
  • the crown head In the rest position, the crown head is outside the watch case.
  • 'WO 2005/038538 shows a control device with push crown for a timepiece with an opening auf usdem supporting element which can be fixed to the casing of the watch or represents the watch case itself.

  • a first stable and a second stable pulled axial position can take, in which the rotation of the drive member, which is predetermined by the crown, the first and the second function controls.
  • the crown can also be pushed from the first axial position to a second axial position for activation of the control independent of the first and second ⁇ function which are controlled by the driving part.
  • First elastic means are provided between the driving part and the head of the crown. Their force is sufficient to overcome the resistance that is provided by the drive part in the transition from the second axial position of the crown in the first.
  • Second elastic means are arranged between the support part and the head of the crown.
