Abstract:
1. A timepiece comprising: a case body having a ring portion that surrounds a transparent cover, the ring portion having a ring groove formed therein that opens to an outer periphery of the ring portion; a rotary bezel rotatably disposed on the case body and having a fitting portion rotatably fitted to the outer periphery of the ring portion, the fitting portion having a guide groove that opens to an inner periphery of the fitting portion and opposes the ring groove; at least one operating screw screwed to the fitting portion from an outer side of the rotary bezel so that a front end portion of the operating screw extends into the guide groove; and a holding member connected to the front end portion of each operating screw so as to permit rotation of the operating screw relative to the holding member, wherein rotation of the operating screw in a tightening direction moves the holding member to a holding position in which the holding member extends into the ring groove to prevent the rotary bezel from being detached from the case body, and rotation of the operating screw in a loosening direction moves the holding member out of the ring groove to a release position in which the holding member extends into the guide groove to permit detachment of the rotary bezel from the case body.
