Abstract (en)

[origin: EP2650735A2] The winding (50) has a guidance (2) leveled with a fulcrum pin (D) and assembled in a cylinder with maximum radius (RMAX). A driving unit drives an energy recharging mechanism. A ferromagnetic or magnetized part drives the winding by a variable magnetic field. An electrically charged part electrically drives the winding by a variable electrostatic field. A paramagnetic conducting ring surrounding the fulcrum pin drives the winding by eddy currents. An internal ferromagnetic part (8) is extended on a radius, which is lower than a minimal radius (RMIN) of a metal peripheral part (9). Independent claims are also included for the following: (1) a winding device (2) a watch assembly.
