<P>PROBLEM TO BE SOLVED: To provide a watch having a structure having a small effect on an internal mechanism even under a severe temperature environment. <P>SOLUTION: The watch 10 includes watch cases 11, 11', 12, 13 for storing the internal mechanism 10X, and an external operation part 14A exposed to the outside and connected to the internal mechanism through the watch cases. The watch is provided with a heat insulating part 21 composed of a material having a lower thermal conductivity than other parts in an operation structure from the external operation part 14A to the internal mechanism 10X. <P>COPYRIGHT: (C)2010,JPO&INPIT |
