路。[Claims for Utility Model Registration] A clock signal generation circuit that generates a clock signal; a minute counter that counts the minute digits of the time using the clock signal; and a carry signal from the minute counter that counts the hour digits of the time. an hour counter; a display circuit that displays the time counted by the hour counter and the minute counter; a group of switches that outputs operating signals by external operation; and correcting the counts of the hour counter and minute counter in response to the operating signals. a display correction circuit that corrects the display of the display circuit; and a minute digit detection circuit that detects a specific time zone based on the count value of the minute counter and outputs a detection signal; a reset control circuit that prevents output of the detection signal in response to the operation signal; and a reset control circuit that applies a reset signal to the minute counter to clear it in response to any operation signal from the switch group when the detection signal is generated. and a reset circuit that applies a control signal to the display correction circuit to increment the count of the hour counter when there is a carry; and a reset circuit that supplies the operation signal to the reset circuit when the detection signal is generated, and when the detection signal is not generated. A correction circuit for a digital timepiece, comprising: an output selection circuit that sometimes supplies the operation signal to the display correction circuit.
