Abstract:
1. An analog electronic watch, comprising: a crystal oscillator; an oscillator circuit; a frequency divider circuit; a constant voltage circuit directly coupled to the oscillator circuit and the frequency divider circuit; a motor; an output control circuit for outputting a motor drive pulse; and a cell, wherein the constant voltage circuit and the output control circuit are powered from the cell, wherein the oscillator circuit and the frequency divider circuit are supplied with a constant voltage generated by the constant voltage circuit as power, wherein the constant voltage is switchable between a first constant voltage and a second constant voltage, wherein the first constant voltage is a voltage which is smaller in absolute value than a cell voltage, wherein the second constant voltage is a voltage which is larger in absolute value than the first constant voltage and equal to or lower than the cell voltage, wherein the constant voltage is switched to the first constant voltage in a case of normal oscillation, and wherein the constant voltage is switched to the second constant voltage in a case where the motor drive pulse is output.
