To provide a wristwatch in which a band can be easily attached to and detached from a case band without using an exclusive tool, it is possible to ensure a sufficient attachment strength of the band with respect to the case band, moreover an injury following upon an attachment/detachment operation of the band can be suppressed, and 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 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. A cam body having a cam part in which an elliptic cam face has been formed is rotatably accommodated in the end piece, and an operation groove of the cam body is exposed. One pair of attachment axles are accommodated in the end piece while nipping the cam part so as to be movable in a width direction of the end piece. Each of both the attachment axles has a cam follower face contacting with the cam face, and is inserted into and withdrawn from the attachment hole by a rotation of the cam body by a dimensional difference between a major axis and a minor axis of the cam part. Biasing bodies are accommodated in the end piece, and the one pair of attachment axles are respectively pushed to the cam face by these biasing bodies.
