An electronic timepiece comprises a casing formed of a thermally conductive material and having a first outer case portion and a second outer case portion connected together to define a space therebetween. The first outer case portion is exposed to the atmosphere and has a first temperature, and the second outer case portion is disposed in physical contact with the wrist of a user during use of the electronic timepiece and has a second temperature different from the first temperature. A thermoelectric element is disposed in the space of the casing for generating an electromotive force due to heat transfer between the first and second outer case portions resulting from the difference between the first and second temperatures. The thermoelectric element has a first support member at one end thereof connected to the first outer case portion of the casing and a second support member at a second end opposite the first end and connected to the second outer case portion of the casing. A conductive element is disposed between the second outer case portion of the casing and the second support member of the thermoelectric element for conducting heat therebetween and absorbing an external force applied to the thermoelectric element.
