PROBLEM TO BE SOLVED: To provide a watch, in which a part around a crown can be replaced when a screw lock function is deteriorated, while maintaining a waterproof property. SOLUTION: An inner winding stem pipe 25, having a male screw part 26 directed toward the outside of the body and a protruded part 25a corresponding to a receive part, is fitted through an outer winding stem pipe 21 having a receive part 21a and brazed to the body 13 so as to be capable of being put in and out. The pipe 25 is prevented from being rotated with respect to the pipe 21, by a rotation stopper means 24 provided across both the winding stem pipes. The pipe 21 is sandwiched between the attachment ring 30 detachably screwed with the pipe 25 and the protruded part 25a, and the pipe 25 is positioned in the axial direction with respect to the pipe. The crown 31 is detachably screwed with the male screw part 26 of the pipe 25. Inner waterproof packing 36 is sandwiched between the crown pipe part 33 of the crown inserted into the pipe 25 and the pipe 25, and outer waterproof packing 29 is sandwiched between the inner and outer pipes 21 and 25.
