Transmission device (100), for example for a watch mechanism (110), in particular for a winding train (100, 201) of a watch movement (120), including an input element (6) intended to be driven only in a first direction, an output element, a first mechanical connection arranged such that the displacement of the input element in a first direction causes the displacement of the output element in a second direction, and a second mechanical connection (9, 9) arranged such that the displacement of the input element in the first direction causes the displacement of the output element in a third direction, the third direction being opposite the second direction.

The mechanical timepiece movement with power reserve indication comprises at least one barrel system connected to a winding wheel of a differential gear and an unwinding wheel of the differential gear. An intermediate wheel of the differential gear is connected to a cam wheel set to drive it in rotation via a reducing stage. A rack, which acts on a power reserve indicator, is in contact with the cam wheel set. When the power reserve is at zero, a locking part of the rack comes into contact with a locking member to lock the movement at an unwinding output of the barrel system or in contact with the unwinding wheel of the differential gear.
