Abstract (en)
[origin: WO0063749A1] The invention relates to a clockwork in which the rotor of a generator (10, 11, 13) is driven by a spring via a multitude of wheels (51, 61, 71) and pinions (50, 60, 70), whereby the operation of the generator is controlled by an electronic control circuit (81). Said wheels and pinions are all grounded in order to prevent spark strikings which can be caused by the charging of voltages due to frictional electricity.
