ABSTRACT:
A diver's watch includes a timepiece exterior assembly including a movement, a hand setting stem pipe, a crown for operating the movement, and a cover pipe. A locking face is formed at an outer peripheral portion of a case body provided to the timepiece exterior assembly. The hand setting stem pipe is fixed to the case body and includes a pipe side screw portion. The crown includes a crown cylinder inserted to inside of the hand setting stem pipe, and a crown head integral with the crown cylinder. The crown head is formed with a crown side screw portion attachably and detachably screwed to the pipe side screw portion, and an engaging end face brought into contact with and separated from the locking face. The cover pipe is arranged to be more proximate to the crown cylinder than the engaging end face. Thereby, the hand setting stem pipe is covered by the cover pipe and the covered state is maintained regardless of a movement in an axial direction of the crown.
