摘要： When it is judged that a chronograph second counter and a chronograph minute counter have measured a maximum measurement time, a maximum measurement control unit controls a drive pulse generation circuit so as to drive and stop a motor such that chronograph hand stops at predetermined positions. When, in this state, a restarting operation is performed on a start/stop button, a normal chronograph measurement operation is restarted. At this time, a mechanical structure has been restored to a reset state, so that even at the time of restarting after the measurement of the maximum measurement time, the load at the starting operation is the same as that of the normal operation, thus generating no sense of incongruity.

摘要： It is configured to include: a secondary battery as a power supply that supplies power at least to a stepping motor; a rotation detection portion that detects a rotation state of the stepping motor; a control portion that drives the stepping motor by selecting a drive pulse having energy corresponding to the rotation state of the stepping motor from a plurality of drive pulses; and a solar battery that charges the secondary battery. Upon determination that it is possible to rotate the stepping motor by an overcharge indicating drive pulse having predetermined energy, the control portion drives the stepping motor by changing a current drive pulse to an overconsuming drive pulse having larger energy than the overcharge indicating drive pulse. It thus becomes possible to suppress deterioration of a secondary battery caused by overcharge without having to provide a dedicated voltage detection circuit, such as a comparator circuit.
