Abstract
A watch has a crown threadedly locked to a stem pipe mounted to a barrel. The barrel has a pipe installation hole and a threaded hole that extends perpendicular to and in communication with the pipe installation hole. The stem pipe has an insertion portion and a barrel outside protruding portion. The insertion portion is inserted in the pipe installation hole such that the insertion portion can be withdrawn from outside the barrel. The barrel outside protruding portion is disposed outside the barrel and has an external thread to which the crown is removably threaded. An engaging recessed portion is formed in the outer surface of the insertion portion. An annular waterproof packing is sandwiched between the pipe installation hole and the insertion portion. A mounting screw is threaded into the threaded hole so as to be removable back and forth. A front-end portion of the mounting screw is inserted in the engaging recessed portion to hold the stem pipe to the barrel.
