In a state in which a chronograph mechanism is not operated, a coupling lever 442 positions a second counting transmission pinion 212b such that the second counting transmission pinion 212b is separated from a second chronograph wheel 214. In a state in which the chronograph mechanism is operated, the coupling lever 442 is moved to rotate such that the chronograph mechanism is operated. As a result, the second counting transmission pinion 212b is in mesh with the second counting wheel 214. By bringing an outer peripheral portion 442f of a guide frame 442d into contact with a contact portion 202d of a chronograph bridge 202, movement of the coupling lever 442 is set. <IMAGE> |
