Title: Watch movement

Abstract: A timepiece movement proposed has a spring which drives, via gearing, a time display and a generator (1) supplying an a.c. voltage. The generator (1) powers, via a voltage-transformer circuit (2), a first capacitative component (10). The first capacitative component (10) powers an electronic reference circuit (3, 4, 5) with a stable oscillator (3, 4) and an electronic control circuit (6, 7, 8, 9). The first capacitative component (10) is charged immediately after the movement is started for the first time by one or more passive components. The one or more passive components are replaced, or supplemented in parallel, by one or more active units as soon as the voltage of the first capacitative component (10) is sufficient to operate the one or more active units, the one or more active units having a lower electrical resistance in the pass direction then the one or more passive components.
