ABSTRACT:
A electronic timepiece having a dynamic frequency divider, a static frequency divider and a reset system, in which a switching means is provided in the voltage supply circuit of the dynamic frequency divider and a gate means is provided between the dynamic frequency divider and the static frequency divider. The switching means is a transistor adapted to be cut off to stop the operation of the dynamic frequency divider in the reset state and the gate means is a digital logic gate adapted to fix the output thereof by an input voltage applied by the reset system, whereby power consumption in the dynamic frequency divider and in the static frequency divider may be reduced.
