Abstract
Abstract An electronic timepiece includes frequency-dividing circuit means for generating a first signal of at least 1 Hz from a signal of a predetermined frequency. This first signal is counted by a time counter. The frequency-dividing circuit and the time counter are reset in response to the closing of a first input switch. Circuitry is provided for releasing the frequency-dividing circuit from its reset condition to generate a second signal of at least 1 Hz as a quick advance signal for time setting in response to the closing of a second input switch.
