Abstract
An electronic timepiece is controlled such that, when an amount of the actual capacity that remains in storage means thereof is found to be less than a predetermined amount as a result of measurement of a voltage between the terminals of the storage means by voltage measurement means , all electrical discharge paths from the storage means to timing means and an electric power generator are completely shut off by the agency of charge/discharge control means , thereby preventing occurrence of wasteful over-discharge from the storage means . As a result, upon resumption of power generation by the electric power generator , entire electric energy generated can be effectively utilized, so that the restart of a time-keeping operation by the timing means is speeded up, and the operation thereafter is stabilized.
