Abstract:
A timepiece movement including a first lever bearing a first drive wheel, a second lever bearing a second wheel for time setting, and a third lever bearing a date correction mechanism. The third lever is mounted to pivot on the second lever and arranged to move between a meshing position, in which the date correction mechanism cooperates with the date display mechanism, and a retraction position, in which the date correction mechanism is disconnected from the date display mechanism. The first and second levers are arranged to occupy at least one date correction position, in which the first drive wheel is kinematically connected to the date correction mechanism and is not kinematically connected to the second wheel for time setting, and a time setting position, in which the first drive wheel is kinematically connected to the second wheel for time setting and is not kinematically connected to the date correction mechanism, wherein the position of the second lever is modified by cooperation between the first lever and the second lever.
