The invention relates to a setting mechanism for a timepiece movement, including a setting gear train, a winder rod adapted to be moved from a first axial position termed a running position to a second axial position termed a setting position, a sliding pinion adapted to be moved from a first axial position in which the sliding pinion is disengaged from the setting gear train to a second axial position in which the sliding pinion meshes with the setting gear train, and a lever interengaged with the sliding pinion and adapted to pivot, when the winding rod is moved from a running position to a setting position and vice versa, in order to move the sliding pinion from the first axial position to the second and vice versa. The setting mechanism further includes, according to the invention, a device for immobilizing the setting gear train. This immobilizing device includes first and second immobilizing arms and an immobilizing wheel interengaged with the setting gear train. The first and second immobilizing arms are adapted, on the one hand, to the interengaged with the immobilizing wheel in a configuration termed locked in which the setting gear train is immobilized and, on the other hand, to be disengaged from the immobilizing wheel in a configuration termed unlocked in which the sliding pinion is free from meshing with the setting gear train. The immobilizing device includes to this end a locking/unlocking lever interengaged with the sliding pinion and adapted to cooperate with the first and second immobilizing arms in order to pass from the locked configuration to the unlocked configuration and vice versa when the winding rod is moved from a running position to a setting position and vice versa.

A winding mechanism is for a timepiece including at least one first and one second power accumulators. The winding mechanism includes a winding stem, a winding pinion and a sliding pinion having face gear toothings, facing one another. The winding stem and the sliding pinion occupy the same axial winding position. The winding mechanism includes a coupling device which cooperates with the winding pinion and is provided to occupy a first coupling position for coupling the winding pinion and the first power accumulator when the winding stem is turned in one direction, the second power accumulator being uncoupled, without any contact with the coupling device, and a second coupling position for coupling the winding pinion and the second power accumulator when the winding stem is turned in the other direction, the first power accumulator being uncoupled, without any contact with the coupling device.
