Timepiece

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 (23, 39) 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 (6, 14, 15) for the moving elements (7, 16) of the said hour display and AM/PM indications and a rocker (36) 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 (37), characterized in that a toothed correcting gear (33, 34), in engagement with means of angular positioning (35), kinematically links the said stepwise drive members (14, 15) with a time zone indicator gear (19, 20), toothing (34) of the said correcting gear being in engagement with a drive finger (36a) of the said correcting rocker (36), in the position of rest of this rocker, corresponding to the relaxing of its restoring spring (37), the trajectory described by this rocker (36), for bringing it from this position of rest into its other limit position, passing via one of the teeth of the said correcting gear (34), this trajectory being chosen so that this tooth is reset into its initial angular position once this rocker (36) 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 (34) of the said correcting gear by the said drive finger (36a).
