PROBLEM TO BE SOLVED: To widen the utilization range of watch by providing a temperature sensor in a back side of a watch so that it contacts with an arm through a back cover, and displaying the measured body temperature on a dial. SOLUTION: A container 6 is made of glass or plastic, and inside thereof is formed in vacuum. A root of a narrow tube 13 is not provided with a necking so that the mercury liquid filled in the narrow tube 13 can be shrunken in the case where temperature is lowered. A part of the container 6 is projected outside of a watch movement so as to form a standing part 15 of the narrow tube 13, and the narrower tube 13 is formed narrower in a surface of a dial 17 so as to surround the surface of the dial 17 in a semi-circular shape. The mercury liquid is expanded and shrunken by body temperature, and extruded to the narrow tube 13, and moved forward and backward clockwise in the narrow tube 13 so as to display the body temperature. With this watch, confirmation of body temperature and early detection of ill are enabled so as to contribute to the maintenance of health. |
