Claims
- 1. Timepiece comprising a 0 to 12 hours display, a minutes display, a time zone display for two geographical locations situated in two time zones separated by 180° from one another, corresponding to the hours displayed by the said hours display, an AM/PM display for distinguishing between the hours preceding and those following the crossing of the meridian by the sun, an indicator for indicating for which of the two time zones displayed the hours are those before or after the crossing of the meridian, stepwise drive members for the moving elements of the said hour display and AM/PM indications and a rocker for the simultaneous correction of the hour display, time zone display and AM/PM indicator, capable of moving between two limit positions, and held in one of the said limit positions by a restoring spring, characterized in that a toothed correcting gear, in engagement with means of angular positioning, kinematically links the said stepwise drive members with a time zone indicator gear, toothing of the said correcting gear being in engagement with a drive finger of the said correcting rocker, in the position of rest of this rocker, corresponding to the relaxing of its restoring spring, the trajectory described by this rocker, for bringing it from this position of rest into its other limit position, passing via one of the teeth of the said correcting gear, this trajectory being chosen so that this tooth is reset into its initial angular position once this rocker has moved into its other limit position, the return of this rocker, from this other limit position to its position of rest via the relaxing of the said restoring spring, causing the driving by one step of the said toothing of the said correcting gear by the said drive finger.
- 2. Timepiece according to claim 1, wherein the said correcting gear is not in engagement with the said stepwise drive member outside of the time zone changing procedure.
- 3. Timepiece according to claim 1, wherein the said correcting gear comprises two concentric pinions tied to one another, the one linked kinematically to the said stepwise drive member, the other linked kinematically to the moving member of the said time zone display and to the moving member of the said indicator for indicating for which of the two time zones displayed, the hours are those before or after the crossing of the meridian.
- 4. Timepiece according to claim 2, wherein the said correcting gear comprises two concentric pinions tied to one another, the one linked kinematically to the said stepwise drive member, the other linked kinematically to the moving member of the said time zone display and to the moving member of the said indicator for indicating for which of the two time zones displayed, the hours are those before or after the crossing of the meridian.
- 5. Timepiece according to claim 1, wherein the said correcting rocker is actuated by an actuating rocker.
- 6. Timepiece according to claim 2, wherein the said correcting rocker is actuated by an actuating rocker.
- 7. Timepiece according to claim 3, wherein the said correcting rocker is actuated by an actuating rocker.
- 8. Timepiece according to claim 4, wherein the said correcting rocker is actuated by an actuating rocker.
