Implementations of a personalized watch are provided. In some implementations, the personalized watch comprises a band having a plurality of removable ornamental links.

A rigidifiable flexible device includes a flexible member having flexibility, a plurality of movable members arranged in a line on a path between one end and the other end of the flexible member along a longitudinal direction of the flexible member, the movable members being movable on the path, a stopper provided at the one end of the flexible member and configured to prevent the movable members from being removed from the path beyond the one end of the flexible member, and a blocking member configured to prevent the movable members from being removed from the path beyond the other end of the flexible member. The length of a portion of the path between the blocking member and the stopper is adjustable so that the movable members are brought into close contact with each other on the path to form an integrated support body.

A jewelry item comprises an elastic element extending over the entire length of the item, a plurality of decorative elements threaded one after the other on the elastic element so as to be slidable with respect thereto, and a plurality of connection elements which are each threaded on the elastic element between a pair of adjacent decorative elements and connect the decorative elements to each other, whereby the adjacent decorative elements are displaceable with respect to each other, sliding on the connection element, between a position of minimum relative distance and a position of maximum relative distance. Each connection element is connected to a first decorative element of the pair of adjacent decorative elements by a first bayonet-type engaging device and to a second decorative element of the pair of adjacent decorative elements by a second bayonet-type engaging device.

A watch band is disclosed. The watch band maintains a substantially constant tension throughout changes in its length while worn by a user. Such changes in length may occur automatically to accommodate changes in the size and circumference of a user's wrist as they move their wrist normally. By maintaining a constant tension, the watch band also maintains a constant force on the user's wrist, and causes a watch body attached to the watch band to also maintain a constant force on the user's wrist. This can increase a user's comfort, since the watch will not get tighter or constrict their wrist as they straighten and bend their wrist. It can also help optimize operation of any sensors in the watch band or watch body that benefit from being held against the user's wrist with a constant force, such as some physiological sensors.

A flexible device includes: a functional element: a first movable element; a second movable element movably connected with the first movable element, in which a movement of the second movable element relative to the first moveable element drives the flexible device to deform.

Disclosed is a wearable electronic device that includes a strap detachably fastened to at least a part of a housing and including a plurality of unit links, a button operatively exposed from at least one of the plurality of unit links, a tension rib secured to an end portion of the button in an internal space of the unit link and having opposite ends that have positions that are changed by pressing of the button, and a hinge pin secured to each of the opposite ends of the tension rib, and disposed to at least partially protrude from left and right sides of each of the unit links, wherein the plurality of unit links are fastened to or separated from each other, such that the hinge pins of a unit link, moving by means of the pressing of the button, are inserted into or extracted from pin-receiving recesses formed in an adjacent unit link.

The jewellery item comprises an elastic element, which extends along an extension direction of the item through the entire length of the item, and a plurality of ornamental elements, which are threaded one after the other on the elastic element so as to be slidable relative to the elastic element and are non-releasably connected in twos to one another. Each ornamental element comprises a hollow body having a pair of longitudinally opposite first faces, namely a right-hand face and a left-hand face, respectively, and a pair of radially opposite second faces, namely an inner face and an outer face, respectively. The right-hand face of each ornamental element has a through opening communicating with an inner cavity of the ornamental element.

A connection structure and a wearing device are provided. The connecting structure includes a connecting member, a latching member, an engaging member, and an elastic member; one of two ends of the latching member is rotatably connected with the connecting member, and the other end of the latching member is provided with a latching portion; the engaging member is provided with an engaging portion corresponding to the latching portion, and the elastic member can engage the latching portion with the engaging portion. The wearing device includes the connection structure. The latching member is rotatably connected with the connecting member so as to enable the latching member to be quickly separated from the engaging member, and two mechanisms could be connected and separated from each other quickly with the connection structure.
