Wrist watch having thermoelectric generator
First Claim
1. A wrist watch having thermoelectric generator manufactured by a process comprising the steps of:
- manufacturing a watch case which is closed by fixedly attaching an insulating body to a metal case body with a glass plate fixedly attached thereto, and securely fixing a case back made of metal to the underside of the insulating body;
housing in the watch case a dial, a movement, and thermoelectric elements serving as the power source for the movement; and
bringing an end face of the thermoelectric elements into contact with the metal case body, and the other end face thereof into contact with the case back;
said metal case body being provided with a pair of band mounting portions formed so as to be protruded from the outer periphery thereof, and a pair of thermoelectric element housings formed on the inner periphery thereof so as to be accommodated inside the band mounting portions, so that each of the thermoelectric elements is housed in the respective thermoelectric element housing.

Abstract
In an attempt to improve balance in size between a dial and a watch case, while securing sufficient power generated by thermoelectric elements, and also achieving miniaturization of a wrist watch having thermoelectric generator, the watch case which is closed is manufactured by fixedly attaching an insulating body to a metal case body, and securely fixing a case back made of metal to the underside of the insulating body, further, the dial, a movement, and the thermoelectric elements are housed in the watch case, and an end face of the thermoelectric elements is brought into contact with the metal case body while the other end face thereof is brought into contact with the case back. Furthermore, the metal case body is provided with a pair of thermoelectric element housings formed on the inner periphery thereof so as to be accommodated inside a pair of band mounting portions formed so as to be protruded from the outer periphery of the metal case body, so that a pair of the thermoelectric elements are housed in the pair of the thermoelectric element housings, respectively.
