Patent ID: 8213268

Claim:
A chronograph timepiece comprising: a chronograph hand indicating time measured at the time of chronograph measurement; a stepping motor rotating the chronograph hand; operating means performing operations of starting, stopping, and resetting chronograph measurement; rotation detecting means detecting whether the stepping motor has rotated or not; drive control means which drive-controls the stepping motor in response to an operation by the operating means and which drive-controls the stepping motor by a drive pulse in accordance with a detection result obtained by the rotation detecting means; and resetting means which mechanically zero-restores and retains the chronograph hand in response to the resetting operation by the operating means and which electrically resets chronograph measurement operation, wherein, when the resetting operation by the operating means is conducted at the time of driving the stepping motor, and the rotation detecting means detects non-rotation, the drive control means drive-controls the stepping motor by a drive pulse of the same polarity as that at the time of previous resetting in response to the restarting operation by the operating means.
