PROBLEM TO BE SOLVED: To facilitate the transfer to power-saving mode by the judgment of a user and reduce the power consumption in an optimum state according to the using state by operating an operating element. SOLUTION: When the operating position of a winding crown switch is in a calendar correcting mode state pulled out in one stage, the count of a power- saving mode counter 101 is started, and the just before position of the winding crown switch is judged. When the just before position is not the time correcting mode position pulled out in two stages, the operation is waited until the winding crown switch position is moved, and then transferred to the power-saving mode when the count value is less than a reference time. A time information memory part 96 counts up the power-saving mode lapsed time, and when a generating device 40 performs a generation with a prescribed electromotive force or more, the operation is transferred to display mode to perform a time restoring processing. According to this, an operator can be prevented from transferring to the power-saving mode at mistake, and the operability is never impaired. |
