Abstract
Watch movement in which the rotor of a generator (10, 11, 13) is driven by a spring over a plurality of wheels (51, 61, 71) and pinions (50, 60, 70), the operation of the generator being regulated by an electronic regulating circuit (81). Said wheels and pinions are all electrically grounded to avoid spark discharges which can be produced by the charging of voltages through frictional electricity.
Claims31
Watch movement in which the rotor of a generator is driven by a spring over a plurality of wheels and pinions, the operation of the generator being regulated by an electronic regulating circuit, wherein said wheels and pinions are electrically grounded.
Watch movement in which the rotors of a generator is driven by a spring over a plurality of wheels and pinions, the operation of the generator being regulated by an electronic regulating circuit, wherein at least certain of said wheels and pinions are electrically grounded, and wherein at least certain of said wheels and pinions are made of non-magnetizable material.
Watch movement in which the rotor of a generator is driven by a spring over a plurality of wheels and pinions, the operation of the generator being regulated by an electronic regulating circuit, wherein said regulating circuit changes the load imposed on said generator, and wherein in the watch movement an oil is used that is ozone-resistant.
