Chronograph timepiece

Abstract

In a chronograph timepiece of a construction in which chronograph hands are electrically drive-controlled and mechanically zero-restoring-controlled, even when backlash is generated due to zero-restoring, the chronograph hands are normally moved at the time of the next time measurement start. A chronograph timepiece includes a drive control unit starting a time measurement operation in response to a start operation of a start/stop button, electrically hand-movement-driving chronograph hands by driving a chronograph hand movement motor according to the time measured, and resetting the time measurement operation in response to a reset operation of a reset button, and a mechanical structure mechanically zero-restoring and setting the chronograph hands in response to the reset operation, wherein the drive control unit drives the chronograph hand movement motor by a predetermined amount even after the reset operation has been performed.
