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.
