Abstract:
A timepiece comprising:a power supply having a chargeable storage member for storing an electromotive force; a timepiece driving circuit driven by the electromotive force stored in the chargeable storage member for driving the timepiece; a plurality of display members for displaying information in accordance with a time based signal output from the timepiece driving circuit; an upper case body made of a thermally conductive material; a rear case cover made of a thermally conductive material; a thermoelectric generator unit for generating an electromotive force based on the Seebeck effect, the thermoelectric generator unit having at least one electrothermic element, a heat absorbing plate, and a heat radiating plate for transferring heat to the upper case body; a power supply operation control circuit for controlling storage of the electromotive force generated by the thermoplastic generator unit to the chargeable storage member; a heat conductive spacer made of a thermally conductive and elastically deformable sheet of material, the heat conductive spacer having a first surface disposed in contact with the heat absorbing plate of the thermoelectric generator unit and a second surface different from the first surface and disposed in contact with an inner side surface of the rear case cover for conducting heat from the rear case cover to the thermoelectric generator unit; and a heat insulating member for thermally insulating the rear case cover from the upper case body.
