An adjustable link for bracelets, including a first half link and a second half link arranged to be assembled to move with respect to each other, including an adjustment, and a locking mechanism cooperating with a complementary locking mechanism in order to form a captive assembly. The adjustment includes a screw, a hole passing through the first half link, and a blind threaded hole extending into the second half link, the through hole and the blind threaded hole facing each other, and being arranged to cooperate with the screw to continuously adjust the position of the first half link and of the second half link in the longitudinal direction in order to adjust the position between a maximum position and a minimum position.

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.

A smart watch includes: a watch dial, a watch band, a monitoring apparatus, and a mechanical transmission apparatus; herein, sensors are set on both front and back surfaces of the watch dial; the watch band is made of hard material and has a multi-section structure; and beginning from a first section of watch band fixedly connected to the watch dial, each section of watch band is a hollow cavity structure that accommodates a next section of watch band; the monitoring apparatus is deployed within the watch dial; the mechanical transmission apparatus is set between the watch dial and the watch band, and is arranged to control extension or retraction of other sections of watch bands for automatically wearing or removal of the watch band. A smart watch automatic wearing method is further provided.

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.

A band includes a pair of members moveable between an open position adapted to receive an article in a channel and a closed position adapted to retain the article within the channel. Each of the members includes a plurality of pivotally attached bistable compliant links, such that when the links are pivoted past a threshold position toward the closed position, the links are biased toward the closed position and such that when the links are pivoted past the threshold position toward the open position, the links are biased toward the open position. An actuator linkage is pivotally connected to at least one of the links, the actuator linkage including an engagement end protruding into the channel when the members are in the open position, such that movement of the article into the channel causes the article to contact and exert actuation forces on the engagement end.
