Bracelet having adjustable length, which includes an adjusting link (6) with two parallel transverse articulation pins (5, 7), a first (5) being fixed and the second (7) being able to pivot with respect to the first (5) so as to reverse the respective positions of the pins and respectively create two, short and long, configurations, and an end link (8) having a first end (8i) pivoted on the second pin (7) and a second end (8j) designed to accept the fixing of the end of one bracelet strand, this second end (8j) having at least one first cutout (8e) designed to house a center link element (10a) of a link at the end of said bracelet strand, and a transverse second cutout (8c) arranged between the two ends (8i, 8j) of the end link (8) to house the first pin (5) of the adjusting link (6) in the short configuration.

An article of jewelry or costume jewelry having at least one elastic or flexible support element and a plurality of ornamental elements fitted in succession on the elastic or flexible support element and coupled two by two along a development direction of the article of jewelry or costume jewelry is provided. Each ornamental element has a first coupling face for coupling to a subsequent contiguous ornamental element, the first coupling face having a raised formation, and an opposite second coupling face for coupling to a previous contiguous ornamental element, the second coupling face having a recess complementary in shape to the raised formation of the previous contiguous ornamental element. Two contiguous ornamental elements are coupled together by accommodating the raised formation of a first element of the two contiguous ornamental elements within the recess of a second element of the two contiguous ornamental elements, with at least one shock-absorbing spacer element arranged therebetween.

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 watch device, more particularly an external watch device comprising two components (1, 21) linked to one another, the first component (1) comprising a first guiding element (10) and the second component (21) comprising a second guiding element (30), the two components being linked to one another in a movable manner by the cooperation of their respective guiding elements (10, 30), wherein the first guiding element (10) comprises a guiding surface in contact at least partially with the second guiding element (30), said guiding surface comprising a polymer material belonging to the family of polyaryl ether ketones (PAEK).

A strap for a wearable device configured to secure to a portion of a body of a user can include a base and a plurality of strap members secured to portions of the base. In some implementations, the base is made of a first material and each of the plurality of strap members are made of a second material, the first material being more pliable than the second material. In some implementations, the base includes a plurality of openings spaced from one another along a length of the base and a plurality of stems. In some implementations, each of the plurality of strap members is a channel secured to one of the stems. In some implementations, the first material includes at least one of rubber and silicone and the second material is a metallic material.

A fixing device is for attaching a band to a watch case by a connecting link. The watch case includes a case middle, at least one pair of lugs, and a case back. The connecting link includes a passage accepting fixing structure of attachment to the watch case. The fixing structure is incorporated into the connecting link and includes an elastic return separating two pivots mounted with the ability to move inside the passage, and each capable of moving between a compressed position and a rest position in which the pivots are designed to rest in a hole formed in each lug of the watch case.
