ABSTRACT:
The oscillating mass is integral with a toothed wheel which is engaged with pinions at the periphery of a plate. Many rotors at the periphery of the plate are located between sections of a peripheral, annular stator. The sections of the stator comprise cores and coils. It is thus possible with a simple construction of small thickness to obtain sufficient efficiency and power of the generator without considerable multiplication of the movement of the oscillating mass. The plate has a recess capable to receive a movement of an electronic watch of an existing caliber. The generator comprising the plate, the oscillating mass, the rotors and the stator constitutes an independent module capable to be assembled with a movement of an existing watch.
