Claims

[Scope of claim for utility model registration] Waterproofing is ensured by the waterproof gasket installed on the winding stem pipe fixed to the reuse or body, and
In the waterproof reuse structure for a watch in which the reuse is screwed onto a screw on the outer surface of the winding stem pipe, the reuse includes an outer cylinder body having a threaded portion formed on the inner surface, and a center hole in which the reuse core slides. The reused core has an inner cylindrical body, and has a collar portion, an irregularly shaped portion, and a winding stem screw hole formed from the outer end, respectively, and the elastic member and the collar portion of the reuse core are inserted into the center hole of the reuse. A waterproof reuse structure for a watch, characterized in that a retaining C ring having an irregularly shaped hole in which the irregularly shaped part of the reuse core slides is fixed to the end of the inner cylinder.
