Chronograph timepiece

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.
