Abstract:
1. An electronic watch including analogue display means formed of at least one hand driven by at least one motor, a time base for controlling means for driving said motor, a rechargeable power source, means for stopping the motor acting particularly on said drive means, time counting means in synchronism with said analogue display means for a sufficient supply voltage, wherein when said stopping means detect a power shortage, said display means are stopped and the corresponding value of said counting means is stored in storage means, said counting means continuing to operate, wherein, as soon as the power supply is sufficient again, time difference calculating means send time difference signals between the stored value and the value of the counting means to said drive means in order to reset said analogue display means to the right time, and wherein depending on the value of the time difference, said drive means commands the motor to rotate in one direction or the other according to the following calculation: 0 hours<(current time−stored time)<6 hours, or 12 hours<(current time−stored time)<−6 hours, then the motor rotates clockwise and 6 hours<(current time−stored time)<12 hours, or 6 hours<(current time−stored time)<0 hour, then the motor rotates anti-clockwise.
