Abstract

An electronic timepiece equipped with a switch means to produce switching pulses in response to actuation of an external operation member, and means for detecting the time intervals between pairs of the switching pulses and producing first control signals indicative of duration of the time intervals. A counter circuit is responsive to the first control signals to provide a second control signal, in response to which a correction signal generation means produces correction signals, the number of which depends on the second control signal.
