Claims

[Claim for Utility Model Registration] A push button structure for a watch, in which a push button shaft consisting of a shaft and a head slides on the inner surface of a pipe fixed to a watch case, and a locking part is formed at the inner end of the shaft. In the pipe, a circumferential groove is formed on the inner surface, and a substantially cylindrical packing consisting of two stages with different outer diameters has a circumferential protrusion on the outer surface of one end with a small diameter and a circumferential protrusion on the outer surface of the other end with a large diameter. A fixed end and a return portion are formed from the other end with a large diameter to the central portion, and the circumferential protrusion at one end of the packing is fitted and fixed into the circumferential groove of the pipe, and the inside of the packing is fixed. A pushbutton structure for a watch, characterized in that a shaft of the pushbutton is inserted into the pushbutton, and a fixed end of the other end of the gasket is fixed between the outer end of the shaft and the head.
