Time zone correction mechanism for a timepiece
12366827 · 2025-07-22 · ·

A timepiece time zone correction mechanism is equipped with a manual control device including two counteracting manual corrector actuators setting in motion a time zone corrector associated therewith including a beak which is configured to bear against a relief of a time zone correction wheel assembly and to cause the assembly to move. The assembly includes a regularly spaced toothing having a first drive level from which a plurality of successive teeth are missing and replaced by a first clearance, and a second drive level parallel to the first drive level, and from which a plurality of successive teeth are missing and replaced by a second clearance. The first clearance and the second clearance are not superimposed with one another. Each time zone corrector cooperates with a single drive level, from among the first drive level and the second drive level, of the time zone correction wheel assembly.

Multifunction correction device for a timepiece and timepiece comprising such a multifunction correction device

A multifunction correction device (100) for a case (2) of a timepiece including a horological movement (1) having at least one function corrector (10, 12) for carrying out various functions of activating, selecting, resetting and/or correcting a piece of information derived from the current time of the horological movement. A control member (130) is capable of moving in rotation about the axis of revolution (X-X) of a control stem (120) between a plurality of angular positions and a protrusion (123) is configured such that the rotation of the control member (130) modifies the angular position of the protrusion (123) about the axis of revolution (X-X) and relative to the horological movement (1).

TWO TIME ZONE DEVICE FOR A TIMEPIECE MOVEMENT

A device applied to a mechanical timepiece movement whether it be hand-wound or automatically wound for measuring two time zones using two twelve-hour hands in which a three-position crown is used to wind, jump the date disc in one-day increments, jump the second time zone hour hand forwards or backwards in one-hour increments, and set the time. In particular, the invention proposes a device for synchronizing the time keeping between both twelve-hour hands and allowing the second time zone hour hand to be independently jumped in one-hour increments without affecting the time measured on the other hands from a single time setting device.
