PROBLEM TO BE SOLVED: To correct time-related data or a date at a second leading position with the starting command control of a chronograph by allowing a pusher head to move in the axial direction from a pause position against a spring force, when the pusher head that is arranged so that it can slide into a recess is pushed in. SOLUTION: A device 1 is provided with a pusher head 2 that is mounted to the end part of a pusher stem 4. The pusher stem 4 is arranged, so that it slides in a cylindrical recess 6 that is provided at the middle part of a clock case. When a pressing force is applied to the pusher head 2, the pusher stem 4 moves in the an axial direction in the recess 6 countering the return force of a spring 12. The spring 12 is arranged in the recess 6 and at the same time touches a bottom part 16 of a gap part 18. An annular groove 20 is provided in the pusher stem 4 and accommodates a sealing gasket 22. The pusher stem 4 moves to a second leading position from a pause position in an axial direction, when pull force is applied to the pusher 2. |
