Abstract
To reduce electric power consumed during the operation of adjusting the indication of time and reduce the time required for the time adjusting operation. Using a second hand driving motor and a hour/minute hand driving motor both capable of rotating in both clockwise and counterclockwise directions, the indication of time is adjusted by driving the second hand driving motor and the hour/minute hand driving motor at times different from each other. The hand driving method (hand driving direction) is determined on the basis of the time elapsed during the power saving mode measured by a time information adjusting part such that the hands are driven in a direction which results in a reduction in the power consumption or the adjusting time.
