Abstract (en)

[origin: EP0816955A1] The clock mechanism has a spring driving a time indicator and an a.c. voltage generator (1) via a wheel mechanism. The generator supplies a voltage converter (2) which feeds a first capacitive component (10) which supplies an electronic reference circuit (3-5) with a stable oscillator (3,4) and an electronic regulator circuit (6-9) with a comparator logic circuit (6). The first capacitive component is charged via one or more passive components immediately after the first cycle of the clock mechanism. The passive component or components can be replaced or augmented by one or more active units in parallel as soon as the voltage on the first capacitive component is sufficient to drive the active units, whereby the active unit resistance in the forward conducting direction is lower than that of the passive component(s).
