Abstract
PURPOSE:To make it possible to correct the second hand of an electronic watch that uses an irreversible step motor by controlling the hands according to the content of a second counter while operating the correction switch. CONSTITUTION:A second counter 3 counts signals from the standard clock to form second information. The rotor of a step motor is rotated according to the content of the counter 3, and the second hand is driven by plural steps to advance the minute hand by one minute. Further, the content of the counter 3 is detected 20 and 21 during operation of a correction switch S. The minute hand is stopped for a specified time or advanced quickly to a specified position according to the content of the counter 3.
