To provide a wristwatch in which a band can be easily attached to and detached from a case band without using an exclusive tool, in which a sufficient attachment strength with respect to the case band can be ensured, and moreover whose use feeling is good. Bow feet each of which has an attachment hole are protrusively provided in a case band, and a bow crotch receiving an end piece (case band connection end part) of a band capable of being attached to and detached from the case band so as to be capable of being put in and taken out is formed between the bow feet. An operation opening is provided in the end piece. A coupler having possessed a tubular rotation body and coupling axles is internally mounted in the end piece. The tubular rotation body has female screws, and the coupling axles are meshed with these female screws. The tubular rotation body is provided while facing on the operation opening, and manual-rotation-operated from an outside of the end piece. The coupling axles are locked to the end piece, and provided so as to be capable of being protruded and immersed with respect to an end face of the end piece in its width direction in accordance with the rotation of the tubular rotation body. The coupling axles having been protruded and immersed are inserted into and withdrawn from the attachment holes, so that an attachment/detachment of the band with respect to the case band is made possible.
