ABSTRACT:
An electronic timepiece includes a frequency supply for providing a relatively high frequency time base signal, a circuit including a frequency converter responsive to the time base signal to provide a relatively low frequency time unit signal, and a time-keeping register responsive to the time unit signal to produce a time information signal. An input means includes an external control to provide an actuation signal when actuated, and an input signal is generated in response to the actuation signal, provision being made for selectively rendering the input signal generating means inoperative. An enabling signal is generated in response to the input signal and the time information signal, and a control responsive to the enabling signal controls the circuit means to correct the time information signal.
