ABSTRACT:
A portable watch comprises a case body having a noncircular pipe-attachment hole extending therethrough, and a winding stem pipe removably inserted from outside of the case body into the pipe-attachment hole and having a noncircular outer peripheral portion that cooperates with the noncircular pipe-attachment hole to prevent relative rotation between the case body and the winding stem pipe. An inner end portion of the winding stem pipe extends beyond the inside surface of the case body into the interior of the case body and an outer end portion of the winding stem pipe extends out from the exterior of the case body, the outer end portion having a male screw section and the inner end portion having an annular groove around the outer periphery thereof. A stopper removably engaged with the annular groove abuts with an interior surface of the case body to prevent withdrawal of the winding stem pipe from the pipe-attachment hole and is disengageable from the annular groove to permit withdrawal of the winding stem pipe from the pipe-attachment hole. A crown has a female screw section screwed together with the male screw section to removably connect the crown to the winding stem pipe.
