Abstract (en)
[origin: US2018267475A1] The invention relates to a winding mechanism of a timepiece comprising at least one first and one second power accumulators, said winding mechanism comprising a winding stem, a winding pinion and a sliding pinion having face gear toothings, facing one another, provided in order to allow driving of the winding pinion by the sliding pinion in the two directions of rotation of the winding stem, said winding stem and the sliding pinion occupying the same axial winding position. The winding mechanism comprises a coupling device which cooperates with the winding pinion and is provided in order 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 said 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 said coupling device.
