  • Patent number: 7329042
    Abstract: 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.

  • Publication number: 20080025158
    Abstract: To provide a portable timepiece in which there has been made such that a constitution for removing, together with a winding stem, a crown from a timepiece movement does not become a restriction factor in regard to a size of a dial, and a factor impairing a design visually showing a periphery part of a timepiece armor assembly thinly. A timepiece movement is built-in in a timepiece armor assembly which possesses an armor case of one-piece structure in which a case bottom wall and a case barrel part have been monolithically made, and in which a taper face has been formed in a peripheral part back face of the case. A winding stem having a stopper engagement part and connected to a movement so as to be insertable/removable from a side is built-in in the armor assembly so as to be movable in a direction intersecting a thickness direction of this assembly. A crown connected to the winding stem is made detachable in the barrel part from a side.
