Abstract
Reduces the consumption of an electronic time piece equipped with a motor 4 driving a display unit 5. A quartz oscillator 1 feeds a supply circuit 3 through a frequency divider 2. The supply circuit 3 of the motor and its control circuit 9 periodically decrease the pulse energy supplied to the motor in response to a reference signal 8.2 provided by a reference counter say every 60 seconds. The energy then supplied to the motor is regulated as a function of the presence or absence of a signal delivered by a detection switch 7 operated by the display unit. If the detection switch does not close, compensating pulses are fed to the motor to catch up the lost seconds and the pulse energy is stepped up.
