Abstract
A wristwatch has a casing containing a movement. An insertion cylindrical portion of a pipe is inserted into a through-hole in a body of the casing, and the pipe is fixed to the body. A push-button has a button shaft engageable with a contact member of the movement through the pipe, and a push operation head connected to the button shaft and disposed outside the body. The button shaft has a first portion integrated with the head and a second portion screwed onto the first portion. The second portion has a diameter greater than that of the first portion and an engagement surface capable of approaching and being separated from a tip of the insertion cylindrical portion. The push-button is biased toward the outside of the body by a spring so the engagement surface is held in contact with the tip of the insertion cylindrical portion.
