とする電子時計。 In electronic watches in which the second hand and minute hand are driven by separate motors, at least the motor that drives the minute hand can be rotated forward and backward, the minute hand moves n seconds, and the second main counting circuit memorizes the second hand position and corrects the minute hand position. The minute hand correction circuit generates a discrimination signal that selects reverse rotation of the motor when the count content of the second main counting circuit is less than 30 seconds and forward rotation when the count content of the second main counting circuit is 30 seconds or more when the second hand returns to zero. An electronic timepiece, characterized in that it is a circuit that detects the count content of the second main counting circuit every time it becomes an integral multiple of n seconds and outputs a minute hand correction signal.
