Abstract
A portable device, such as a wristwatch, has a push-button that includes an engaging portion, and the push-button is mounted on a watch sheath. A locking member and a leaf spring are arranged on the watch sheath. The locking member is movable between a locked position in which the push-button is held at a predetermined position by engagement with the engaging portion and an unlocked position where operation of the push-button is allowed. The locking member is urged by the leaf spring toward the unlocked position. A circular operating ring surrounds an hour plate mounted on the watch sheath and the operating ring is rotatably mounted to the watch sheath from the front side. The movement of the locking member between the locked position and the unlocked position is interlocked with a rotating operation of the operating ring.
