Abstract: According to an electronic timepiece of the invention, when a secondary battery is in an uncharged state and an oscillation circuit, a display unit, and a CPU are restored from an inoperable state to a normally charged state which makes the respective members to be operable, the electronic timepiece activates and oscillates the oscillation circuit when a secondary battery voltage reaches a predetermined first voltage (for example, 0.9 V), and cancels a reset of the CPU when the secondary battery voltage reaches a predetermined second voltage (for example, 1.2 V), and starts a time-of-day display on the display unit when the secondary battery voltage reaches a predetermined third voltage (2.2 V).
