Abstract
To provide a wristwatch in which an attachment/detachment operation of an end piece of a band in regard to bow feet of a case band is easy. A concave part is formed in a back face of an end piece of a band and, under a state in which the piece is received in a bow crotch between adjoining bow feet, through-holes facing on attachment holes of the bow feet are respectively provided in side walls of the piece. The rotation member is rotatably held in the concave part. From one end to the other end, one pair of cam holes of shapes in which distances in regard to a center of a rotation member become gradually small are point-symmetrically provided in the rotation member, and a rotation operation groove is provided between these cam holes. Connection end parts of one pair of connection members forming L-shapes are passed through the through-holes, and cam follower end parts of the connection members are inserted into the cam holes. There is made such that, when the rotation member is rotated and the cam follower end parts are disposed in the one ends of the cam holes, the connection end parts are inserted into the attachment holes and, when the rotation member is rotated and the cam follower end parts are disposed in the other ends of the cam holes, the connection end parts are pull-drawn from the attachment holes.
