Abstract
The mechanical timepiece movement with running reserve indication comprises at least one barrel system with a winding output connected to a winding wheel of a differential gear, and with an unwinding output connected to an unwinding wheel of the differential gear. It includes a locking wheel set driven in rotation by an intermediate wheel of the differential gear. The locking wheel set is connected to a running reserve indicator to display the running reserve. The locking wheel set includes a locking element for coming into contact with the unwinding wheel of the differential gear when the running reserve is at zero, in order to lock the timepiece movement.
Claims11
A mechanical timepiece movement with running reserve indication, comprising at least one barrel system with a winding output connected to a winding wheel of a differential gear, and with an unwinding output connected to an unwinding wheel of the differential gear,
- wherein the movement includes a locking wheel set driven in rotation by an intermediate wheel of the differential gear, the locking wheel set being connected to a running reserve indicator to display the running reserve,
- wherein the locking wheel set includes a locking element for coming into contact with the unwinding wheel of the differential gear, when the running reserve indicator indicates zero in order to lock the timepiece movement, and
- wherein the locking wheel set includes a first wheel fixed on the axis of rotation and in direct contact with the intermediate wheel of the differential gear to be driven in rotation.
