Abstract:
An electronic timepiece comprises a drive module configured to drive a hand, an electricity generation module, first and second capacitor modules, the second capacitor module having smaller capacitance than the first capacitor module, and an auxiliary drive control module which causes the drive module to perform the auxiliary driving when the charge level of the second capacitor module exceeds a third level indicating an amount of electricity which enables the auxiliary driving, and waits until the charge level of the second capacitor module exceeds the third level after performing the auxiliary driving.
