20080285391 | Timepiece - To provide a timepiece in which operations for a rotation stop of a bezel and its release are easy, and reliability and a durability of the rotation stop are high. A bezel is disposed in a bezel disposition part of a case band so as to be capable of rotation-operating, and positioning parts and lock parts, which comprise plural concave-convex portions juxtaposed in a direction of the rotation, are formed in a back face of the bezel. To the case band, there is attached a clip stop mechanism (positioning means), which permits clockwise and counterclockwise rotations of the bezel by engaging with and disengaging from the positioning part, and holds the bezel in a position in which the rotation of the bezel is stopped. Between the case band and the back face of the bezel, a lock member is disposed so as to be movable in a diameter direction of the case band. The member has operation convex parts, pushing-in-operated from an outer periphery side of the bezel, a holding groove (holding part), and a stopper part inserted to and retracted from the lock part. To the case band, there is attached a click stop mechanism (holding means) engaging with the holding groove when the lock member was moved to a position in which the stopper part engages with the lock part, thereby holding the lock member. | 11-20-2008 |
