Abstract
An electronic timepiece includes a solar power source, a voltage stabilizer circuit that generates a constant voltage by using power supplied from the solar power source, and a control circuit that clocks the time by driving a rotating body at first hand operation speed and at second hand operation speed which is faster than the first hand operation speed. The control circuit selects a voltage of the solar power source so as to drive the rotating body in a case of the first hand operation speed, and selects at least any one voltage of the constant voltage and the voltage of the solar power source so as to drive the rotating body in a case of the second hand operation speed.
