发明名称 Analogue electronic watch having a device for resetting the time following a power shortage
摘要 The electronic watch includes analogue display means (1) formed of at least one hand (2) driven by at least one motor (3), a time base (4) for controlling means (8) for driving said motor, a rechargeable power source (9), means (14) for stopping the motor (3) acting particularly on said drive means, and time counting means (18) in synchronism with said analogue display means (1) for a sufficient supply voltage. When the stopping means detect a power shortage, the display means are stopped and the corresponding value of the counting means is stored in storage means and the counting means continue to operate. As soon as the power supply is sufficient again, time difference calculating means (20) send time difference signals (21) between the stored value and the value of the counting means to the drive means in order to reset said analogue display means to the right time.
