摘要： A control circuit for an electronic timepiece in which a digit selection switch is connected to a timer circuit which generates an output signal only when the digit selection switch is actuated for a given interval of time. An output signal generation means is coupled to the timer circuit and rendered operative in response to the output signal from the timer circuit to generate an output pulse. A digit selection circuit is responsive to the output pulse from the output signal generation circuit for selecting a digit to be corrected in a timekeeping circuit. The output signal generation circuit comprises a first means responsive to the output signal from the timer circuit and a second means normally inhibited by the first means and rendered operative when the first means has been set by the output signal from the timer circuit, whereby a time correction mode is selected under a circumstance in which the digit selection switch is continuously actuated for the given period of time and, thereafter, a digit to be corrected is selected each time the digit selection switch is actuated. The timepiece has a number of function display marks corresponding to respective functions, and a display device is arranged so as to permit a display of function display marks corresponding to the functions which have been placed in selected state.
