Abstract
An electronic timepiece in which an operating state of a timepiece circuit is controlled by a control circuit composed of a counter responsive to clock pulses from the timepiece circuit, a digital/analog converter for converting a digital output signal from the counter to an analog output signal, a potentiometer adapted to generate an analog input signal, and a comparator for comparing the analog output signal and the analog input signal to generate an output signal which is applied to the counter to control the same by which a control signal is generated to control the operating state of the timepiece.
