A rotary bezel (1) is stopped at a lower stop point by a positioning elastic member (105) held by a positioning groove (12) of the rotary bezel (1) and a positioning projection (25) of a case body (2). At this moment, a rotation stop portion (43) provided to a rotation restricting ring (4) is engaged with a single or a plurality of rotation stop holes (23) perforated to the case body (2) by which the rotation restricting ring (4) cannot be rotated. By pulling the rotary bezel (1) to move in a vertical direction, a positioning elastic member (105) held by a positioning groove (12) of the rotary bezel (1) is bent and rides over the positioning projection (25) of the case body (2). At this moment, the positioning elastic member (105) held by positioning groove (12) of the rotary bezel (1) interferes with a positioning projection upper inclined face (27) of the case body (2) by which the rotary bezel (1) can be stopped at an upper stop point and at the upper stop point, the rotary bezel (1) can stably be rotated. Under the state, engagement between the gear-like recessed and projected portion (13) of the rotary bezel (1) and a rotation restricting portion (41) of the rotation restricting ring (4) fixed to the case body (2) is completely released and the rotary bezel (1) can freely be rotated. <IMAGE> |
