Abstract: Watch comprising a case containing an energy accumulator recharged by a winding mechanism, this watch is arranged to receive, attached to the case or in immediate proximity thereto, an additional self-winding mechanism arranged to be worn by a user at the same time as the watch and comprising a transmitter wheel set arranged for contactless cooperation with a receiver wheel set comprised in the winding mechanism, by remote interaction under the action of a field in the air-gap between the transmitter wheel set and the receiver wheel set, the intensity of the field and the maximum air-gap distance being defined to transmit to the receiver wheel set, to recharge the energy accumulator, a torque or a force imparted by a user to the transmitter wheel set, and the additional self-winding mechanism is removable and portable with respect to the case.
