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.
Claims6
An electronic timepiece comprising:
- a drive module configured to drive a hand;
- an electricity generation module;
- first and second capacitor modules configured to store electricity supplied from the electricity generation module, the second capacitor module having smaller capacitance than the first capacitor module;
- and
- an auxiliary drive control module configured to be capable of causing the drive module to perform an auxiliary driving by using electricity from the second capacitor module, until a charge level of the first capacitor module rises to a second level indicating recovery after the charge level of the first capacitor module has dropped to a first level, wherein
- the auxiliary-driving can be performed by a predetermined amount of electricity, and with a movement pattern in which the hand is driven and thereafter returned to a predetermined return position, and
- the auxiliary drive control module 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 the auxiliary drive control module waits until the charge level of the second capacitor module exceeds the third level after performing the auxiliary driving.
