Abstract
A circuit in an electronic timepiece including a battery, a crystal oscillator, a frequency divider, a display driver and a display for reducing the magnitude of the voltage to one or more of the oscillator or driver circuits after the timepiece is turned on. The circuit initially allows the magnitude of the voltage applied to be the same as that of the battery. After some predetermined time has elapsed, the circuit reduces the applied voltage thereby reducing the power consumption and extending battery life.
