PROBLEM TO BE SOLVED: To accurately and rapidly correct time while miniaturizing a device and reducing costs in an automatic correction clock. SOLUTION: An automatic correction clock is provided with a first drive system 20 for driving a second hand, a second drive system 30 for driving a minute hand and an hour hand, a detection sensor 40 for detecting the positioning of a second hand wheel 23, a minute hand wheel 34, and an hour hand wheel 36 at a position corresponding to specific time based on an electronic wave signal. The control part simultaneously drives the first and second drive systems for correcting the time of the second, minute, and hour hands. |
