Abstract:
An electronic timepiece comprising: a thermoelectric element for generating an electromotive force in response to a temperature difference thereacross; a booster circuit for boosting the electromotive force generated by the thermoelectric element; a storage mechanism for storing electrical power utilizing the electromotive force boosted by the booster circuit; power monitoring means for monitoring the electromotive force boosted by the booster circuit to detect whether the boosted electromotive force is lower than a threshold value; an oscillation circuit connected to be driven by electrical power stored in the storage mechanism; a dividing circuit for frequency-dividing a signal output by the oscillation circuit; a display mechanism for displaying time; a display driving circuit for driving the display mechanism to display time in accordance with an output signal from the dividing circuit; and a display drive controlling circuit for stopping operation of the display driving circuit when the power monitoring means detects that the boosted electromotive force is lower than the threshold value.
