Abstract
An electronic module for regulation of a watch movement with mechanical winding includes a generator ( ) permitting converting the mechanical energy supplied by the mechanical watch movement into a measuring signal (G+;G−) and an electronic circuit ( ) supplied by the generator. The electronic circuit includes an energy dissipation circuit ( ) permitting applying at least two separate braking couples more than zero to the generator ( ). The electronic circuit ( ) also includes a counter to control the braking circuit. The braking couple selected by the control circuit depends on the advance of the generator and is reduced, without being suppressed, when the measuring signal (G+;G−) passes through an extreme.
