To provide a watch excellent in maintenance around a winding stem pipe.

This watch 10 is equipped with the winding stem pipe 21 screwed detachably into a pipe fitting hole 17 on a case band 13. In the watch 10, a winding crown head 32 of a winding crown 31 is screwed in the covering state into the pipe end 23 of the winding stem pipe 21 arranged outside the case band 13, and thereby careless rotation of the winding crown 31 can be prevented. A ring receiving part 17a is provided on either of the pipe fitting hole 17 and an insertion part 22 of the winding stem pipe 21 screwed into the hole 17, and a soft and elastic friction ring 29 is supported on the other. The friction ring 29 is in elastically close contact with the ring receiving part 17a to thereby baffle the winding stem pipe 21. Hereby, the watch is characterized by preventing careless rotation of the winding stem pipe 21 caused by winding crown operation, and enabling the winding stem pipe 21 to be mounted on or dismounted from the shell 13 in maintenance.
