Abstract
A device for winding automatic watches, including an electrical energy source and a receptacle support including a surface configured to receive in abutment a back cover of a watch, the device configured to generate a magnetic and/or electrostatic field or eddy currents, in a fixed position underneath the bearing surface and generate, on a substantially annular angular sector, a magnetic and or electrostatic field that varies as a function of time and whose direction is orthogonal to the bearing surface, or generating eddy currents that vary as a function of time. The device can be provided for a watch including an automatic winding mechanism with an oscillating weight including a first ferromagnetic inner part and a second heavy metal peripheral part, and possibly with a paramagnetic conductive disc coaxial to the oscillating weight.
