ABSTRACT:
To provide a timepiece in which a position alignment of a bezel is easy, and a position-aligned bezel can be made so as not to be carelessly rotated. A portable timepiece possesses a case band, an annular bezel, a click member, a coil spring, and a lock member. In the case band, there are provided an annular bezel disposition groove opening upward and to an outer periphery face, and an accommodation hole extending in a vertical direction while opening to a bottom face of this groove. Bezel is disposed, while being fitted to the disposition groove, so as to be rotatable in both directions of a clockwise direction and a counterclockwise direction in regard to the case band. A click member engaging with and disengaging from an engagement part comprising plural irregularities juxtaposed in a rotation direction in a back face of the bezel facing on the bottom face is accommodated in the accommodation hole so as to be vertically movable. In the accommodation hole, there are accommodated the spring pushing the click member to the engagement part, and the lock member. The lock member moves between a retention position retaining the click member to a state in which this member engages with the engagement part and a retracted position allowing a click operation of the click member, by an operation from an outside of the case band.
