ABSTRACT:
A battery powered electronic timepiece of the type comprising an oscillat adapted to generate high frequency electric pulses, a frequency divider arranged to receive said high frequency electric pulses and to deliver low frequency electric pulses, a stepping motor adapted to be controlled by said low frequency electric pulses and to drive display means and a battery arranged to energize the oscillator, frequency divider and stepping motor, a condensor is coupled to the oscillator and frequency divider and a switch, which receives control signals from the frequency divider, is arranged to provide a low resistance path from the battery to the condensor in the intervals between motor stepping pulses, and a high resistance pass from the battery to the condensor during motor stepping pulses, whereby during motor stepping pulses the oscillator and frequency divider are energized substantially entirely from the condensor.
