Thermoelectrically powered wrist watch

摘要

A thermoelectriocally powered wristwatch has an endothermic plate affixed to the underside of a case back for absorbing external heat, and a thermal conduction plate for conducting the absorbed heat through heat transfer pins to a thermoelectric conversion element which converts the absorbed heat to electricity for powering the wristwatch. Thermal conduction preventive packings formed of a material having low thermal conductivity, such as plastic or rubber, are interposed between the endothermic plate and the case back and between the case back and the thermal conduction plate.
