Abstract
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.
