Abstract
To provide a timepiece whose bezel can be easily attached and detached by a user without requiring a special-purpose tool. A male screw, an annular groove disposed downwardly away from the male screw and an annular clearance groove positioned between the annular groove and the male screw are provided on the outer periphery of an annular convex of a case band to which a cover glass is attached. A soft and resilient engagement ring is fitted to the annular groove such that the engagement ring projects out from the annular groove. A bezel includes on its inner periphery a female screw disposed within the clearance groove for releasably engaging with the male screw and an annular engagement convex having a stopper slope. The stopper slope is disposed below the female screw to tightly contact with the outer periphery of the ring. The bezel attached in a condition in which the ring tightly contacts with the stopper slope is rotated in a loosening direction of the bezel through a screw-engagement between the screws. Subsequently, the engagement convex passes through the ring upwardly to be positioned above the ring, and the bezel is finally separated.
