A jewelry item comprises a ring-shaped spring; a ring-shaped chain comprising a plurality of chain links wherein each chain link is slidably attached to the support element; each chain link comprises a plate having a first surface facing the spring and a second surface opposite to the first surface; a seat and a hook opposite to each other, the hook is inserted into a seat of a subsequent chain link so as to lock the chain links to each other while allowing the chain links to reversibly slide from a contact position to a distanced position with respect to each other.

A bracelet having articulated links, including an articulation between a first link and a second link including a tongue that pivots in an opening between side flanges of this first link together forming a double clevis fitting, wherein, in the articulation, the first link or respectively the second link includes at least one external trunnion or respectively at least one internal trunnion arranged to pivot in an internal half-bearing of the second link, or respectively in an external half-bearing of the first link, the second link or respectively the first link includes at least an upper part and a lower part arranged to enclose and conceal therebetween each external trunnion or respectively each internal trunnion.

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 wearable electronic device is provided. The wearable electronic device includes a main body and a wearing unit that allows the main body to be worn on a user's body. The wearing unit may include a first wearing member extending from the main body, a binding member coupled to the first wearing member to be moved in a longitudinal direction of the first wearing member, and a driving member installed in the first wearing member to move the binding member.

A timepiece component, having a first part and a removable cap, which is able to adopt a fastening configuration in which the removable cap is fastened to the first part, and a free configuration in which the cap is separated from the first part. The first part comprises at least two latching members intended to cooperate with at least two corresponding assembly members of the cap in the fastening configuration. The cap or the first part is elastically deformable from a rest position to a deformed position which allows for positioning and removing for passing from the fastening configuration to the free configuration of the timepiece component and vice versa The rest position allows stably maintain the fastening configuration of the timepiece component in which the at least two assembly members of the cap arc in engagement with the at least two latching members of the first part.
