Abstract: A thermoelectrically-powered wrist watch in which thermal energy picked up by the metal back of the watch casing is transferred to the hot pole of an electrothermal generator housed within the casing. To avoid thermal shunts which cause heat losses and reduce the efficiency of the generator the metal carrier for the watch movement is thermally insulated from the upper component of the casing which, in turn, is thermally insulated from the back thereof. In addition or alternatively, the casing back is partially constituted by thermal insulation material.
