PROBLEM TO BE SOLVED: To enable a normal operation at a start operation and a reset operation, in a chronograph timepiece whose chronograph hands are electrically drive-controlled and mechanically controlled at zero restoration. SOLUTION: In the chronograph timepiece, a mechanical control means releases the setting of the chronograph hands 14, 15 in response to the start operation of a start/stop button 18, a contact portion 34 is then placed in a start state, and an electrical control means starts a time measurement operation to electrically hand-movement drive the chronograph hands 14, 15, and after a contact portion 32 is placed in a reset state in response to a reset operation of a reset button 19 and the electrical control means electrically resets the time measurement operation, the mechanical control means mechanically zero-restores and sets the chronograph hands 14, 15.
