Abstract
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.
