A watch is offered in which the life of the threadedly engaged portion between the stem pipe and the crown can be improved and which has an internal thread capable of being machined relative to the crown easily and accurately. The watch is based on a watch in which the crown is threadedly locked to a stem pipe mounted to a barrel. The stem pipe has a barrel outside protruding portion provided with an external thread. The crown has a crown shaft and a crown ring having an internal thread removably threaded to the external thread, the ring being connected to the crown shaft. The crown shaft has a barrel insertion cylindrical portion which is smaller in diameter than the crown ring and inserted in the stem pipe and a ring connection portion mounted integrally with this cylindrical portion and connected to one end portion of the crown ring. |
