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