Abstract

An electronic timepiece suitable for use with different types of batteries having different voltages, and including a stepping motor 6, an oscillator 1, a frequency divider 2 and a motor control circuit 5, comprises a battery voltage detector 8 and a pulse shaper circuit 9 capable of producing pulses of different durations. The voltage detector circuit 8 controls the pulse shaper circuit 9 to cause it to supply the motor control circuit with pulses whose duration depends upon the detected battery voltage, whereby the drive pulse power will be substantially the same irrespective of the type and voltage of the battery fitted. In another embodiment trains of short pulses are used instead of single pulses and the duty cycle of the short pulses is varied. <IMAGE>
