Abstract:
1. A device for winding watches comprising: a containment structure accommodating a motor; a coupling which can be associated with a crown of a watch to be wound to transmit rotation thereof to the watch crown; transmission means that connect the motor to said coupling to produce rotation of the coupling about a rotation axis thereof; a motor controller that comprises a program for identifying by means of a suitable algorithm a sufficient winding value of a watch at which rotation applied to said crown is stopped, the sufficient winding value corresponding to a maximum value of the second derivative of the trend of the current absorbed by said motor; and a seat for stably accommodating the watch to be wound, said seat being defined on an upper surface of said containment structure and having a shape suitable to provide shape mating with the case of the watch to be wound and align a rotation axis of the crown of the watch to be wound with the rotation axis of said coupling upon placement of the watch in said seat, and wherein said seat comprises a memory medium that contains information related to a rotation to be applied to the coupling in order to perform a sufficient winding of a specific model of watch to be wound and in accordance with the sufficient winding value identified by said program, said containment structure being provided with means for reading said information.
