A bracelet may be adjustable. The bracelet may be a portion of a watch and/or jewelry. The bracelet may include a clasp with a track that includes a plurality of first openings and second openings. A first end of the bracelet may include a link with a pin. The pin may be disposed in the track, and the length of the bracelet may be adjusted by moving the pin along a length of the track. The pin may have a length and a cross-sectional shape perpendicular to the length. The cross-sectional shape may allow the pin to travel along the length of the track when the link is disposed at an angle relative to the length of the track and may restrict the pin from travelling along the length of the track when the link is approximately parallel to the length of the track.

An arrangement for the elastic articulated link between two components of a horological assembly, wherein it comprises at least one link shaft and one spring (25; 25) working in torsion mode between the two components to exert an elastic return force.

A watch type mobile terminal includes: a body having a power supply unit, a printed circuit board, and a display unit formed to implement a touch input thereon; a band unit formed to be wearable on a user's wrist by being connected to the body, and formed such that at least part thereof is wound or unwound in the body; and a length control unit configured to implement winding or unwinding of the band unit such that a length of the band unit is controllable in accordance with a user's wrist size.

Clasp for a watch bracelet comprising a cover connected on a first side to a first bracelet strand and on a second side to a second bracelet strand, a connecting means being inserted between the second bracelet strand and the cover of the clasp, the connecting means comprising an end link sliding along a longitudinal direction of the clasp between a first position in which the end link is at least partially engaged in the cover of the clasp, and a second position in which the end link is disengaged from the cover of the link, the end link comprising a push-button which, when pressed, causes a toothed element to change from a first position, in which the toothed element is in mesh with a rack toothing integral with the cover of the clasp, to a second position, in which the toothed element is released from the engagement thereof with the rack toothing; the clasp being characterized in that the end link includes a housing in which there is arranged at least one spring, the spring being covered by the push-button.

A wearable band may be coupled with an electronic device, and a user can secure the electronic device around a body part of the user with an attachment mechanism of the wearable band. The wearable band and/or the attachment mechanism can include an incremental adjustment mechanism. The attachment mechanism can produce an initial fit or tightness when the wearable band is secured around the body part of the user. The incremental adjustment mechanism can be used to incrementally adjust the initial fit of the wearable band on the body part. The incremental adjustment mechanism is configured to allow the user to adjust the fit or tightness of the wearable band around the body part more finely than the attachment mechanism.

A bracelet clasp including a securing member provided with an adjustment device for adjusting the useful length of the bracelet, this adjustment device including a base plate secured to the second end of the first strip, a cap pivotally hinged to the base plate, the first strand passing between the base plate and the cap and being held by a holding device, second device for locking the cap in the closed position on the base plate. The second locking device include a push-piece arranged to be moved between a first rest position in which the cap is locked in a closed position on the base plate, and a second pushed-in position in which the cap is unlocked from the base plate.

A band device according to an aspect of the present disclosure includes a sensor unit, and a band unit that is linked to the sensor unit and forms a hollow part together with the sensor unit. The band unit includes an end piece section to which a watch head section is attached, and an engaging section that makes detachable engagement in a state where the band unit is wrapped around a wrist.

An adjustable watch strap having a micro-adjustment system for providing micro adjustments to the circumferential length of the watch strap, in addition to existing standard adjustments. The micro adjustment system is integrated into a buckle (e.g., deployment buckle) and is configured to provide a plurality of microadjustments between standard adjustments or beyond a last or first standard adjustment.

An adjustment device (100; 100; 100) for adjusting the length of a bracelet, having at least one adjustment assembly (10; 10; 10) movable relative to a clasp cover (7; 7; 7), the adjustment assembly and the cover being respectively provided with a first and a second fixing element (11, 71; 11, 71; 11, 71) for their respective fixing according to several positions capable of inducing different bracelet lengths, and also being provided respectively with a first and a second indexing element (21, 72; 21, 72; 21, 72) for their temporary respective positioning according to one of the several positions, the adjustment assembly (10; 10; 10) also comprising a guiding device including a first guiding element (3, 4, 5; 3, 4, 5; 3, 4) cooperating with a second guiding element (74; 74; 74) of the cover (7; 7; 7) to guide the displacement of the adjusting assembly (10; 10; 10) relative to the cover (7; 7; 7), the first indexing element (21; 21; 21) being independent of and/or distinct from the first guiding element (3, 4, 5; 3, 4, 5; 3, 4) and/or the second indexing element (72; 72; 72) being independent of and/or distinct from the second guiding element (74; 74; 74).

A length adjusting device has a guiding track and a controlling assembly. The guiding track has a guiding structure and a locking structure. The controlling assembly has a connecting base, an engaging body, a switch base, a spring, a switch, and a controlling body. The guiding track is mounted between the connecting base and the engaging body. The engaging body is selectively engaged with the guiding track. The switch is combined with the connecting base and has a switching recess. The spring is mounted between and compressed by the engaging body and the switch base. The switch is selectively engaged in the switching recess. The controlling body is mounted on the switch base and has a gear engaged with the guiding track.
