Abstract: In an electronic watch having an oscillator for producing a time base signal and stepping motor, drive pulses are produced for normally driving the motor under normal load conditions. The rotation and non-rotation of the motor in response to the last drive pulse is detected in response to a detecting pulse, and if non-rotation has been detected, a predetermined plurality of correction pulses are applied to the motor for driving same, the correction pulses being sufficient to drive the motor under a high torque loading. In this way, power consumption is decreased since a high power driving is saved only for high torque loading conditions.

Abstract: An electronic timepiece including a stepping motor and a time-indicating hand moved in a stepwise manner by the stepping motor for indicating time. During normal operation the time-indicating hand moves at a normal periodic rate.

Additionally, the correcting pulses cause the rotor, and the time-indicating hand to rotate at a rate different from the normal periodic rate to alert the timepiece user that some condition exists tending to cause non-rotation of the stepping motor.

Abstract: An electronic timepiece reduces power consumption by normally driving the stepping motor with a short pulse and driving the motor with a wide pulse under heavy load conditions by sensing the rotor position.

If the second voltage drop is larger, then the rotor is not rotating whereupon the wide pulse is used to drive the motor.
