Abstract
An electronic timepiece is formed of a power generating device for generating power, a control device for driving on receipt of a power supply from the power generating device, a display device for displaying a time by an operation of the control device, a detecting device for detecting a state of the power generating device, and a deciding device for deciding whether or not the power generating device generates power based on a detection signal sent from the detecting device. The control device controls such that a power generating state of the power generating device is displayed on the display device based on a decision of the deciding device. It is possible to reduce power consumption by stopping hands if required.
