发明名称 Watch
摘要 There is provided a watch in which a crown and associated parts, excluding a winding stem pipe, can be replaced when the screw locking function is impaired. The watch includes a case band having a pipe attachment hole, a winding stem pipe, a ring gasket made of elastic resin material, a ring, and a crown. The winding stem pipe is inserted into the pipe attachment hole and fixed to the case band in a liquid tight manner. Outer grooves are formed on the outer cylindrical surface of an off-case band projection of the winding stem pipe that is disposed outside the case band. The removable gasket is fitted on and in close contact with the outer cylindrical surface of the off-case band projection such that the outer grooves prevent the rotation of the gasket. The ring has a male screw formed on the outer cylindrical surface thereof and inner grooves formed on the inner cylindrical surface thereof. The ring is removably fitted on the outer cylindrical surface of the gasket. The gasket is compressed and sandwiched between the ring and the off-case band projection such that the inner grooves prevent the rotation of the gasket. The crown removably engages the male screw of the ring.
