Abstract
To provide an analog electronic timepiece which prevents a crystal oscillation circuit from malfunctioning even if a battery voltage is lowered at motor loading. An analog electronic timepiece is equipped with a crystal vibrator, an oscillation circuit, a frequency division circuit, a constant voltage circuit, an output control circuit, and a motor. The analog electronic timepiece is configured in such a manner that the constant voltage circuit has a voltage holding circuit connected between a gate of an output transistor and a power supply terminal, and the oscillation circuit and the frequency division circuit are operated with a constant voltage generated by the constant voltage circuit as a power supply.
