摘要:
An electronic timepiece adapted to perform time correction in response to a train of time correction pulses transmitted from another electronic timepiece. The electronic timepiece comprises a detecting means to detect the train of time correction pulses; a writing-in signal generator circuit to generate writing-in signals in synchronism with a synchronizing signal contained in the train of time correction pulses, and a writing-in gate circuit means to perform writing-in of the train of time correction pulses into a timekeeping circuit of the timepiece as new current time data in response to the writing-in signals.
