PROBLEM TO BE SOLVED: To improve the durability and reliability of a thermoelectric element by preventing stress from being applied to the thermoelectric element even when an external force such as an impact is applied to a watch, and simultaneously to provide a structure capable of preventing a heat conduction failure resulting from a dimensional error. SOLUTION: The thermoelectric element 60 is arranged between a movement 40 and a rear cover 70. One end of the thermoelectric element 60 is connected to the rear cover 70 so as to conduct heat, and an other end of the thermoelectric element 60 is connected to a heat conductor 50 so as to conduct heat. The heat conductor 50 is connected to an upper drum 10 so as to conduct heat, and furthermore is formed of a sheet shaped elastically deformable material. A clearance is formed between a connecting part of the heat conductor 50 and the thermoelectric element 60, and the movement 40. |
