A band includes at least three members pivotably connected to one another so as to be pivotable between open and closed positions. A first member includes first and second permanent magnets disposed at opposite ends thereof, a second member includes a third permanent magnet and a third member includes a fourth permanent magnet. The first and second members are configured such that when they are pivoted with respect to each other past a threshold position toward the closed position, they are biased toward the closed position by forces created by the first and third magnets and when they are pivoted with respect to each other past the threshold position toward the open position, they are biased toward the open position by forces created by the first and third magnets. The first and third members are similarly biased by forces created by the second and fourth magnets.

The method for configuring a wristwatch strap for a given wearer includes: firstly, acquiring (E1) at least one morphological data item (1; 2) of the wearer of the bracelet; intermediately, automatically determining (E2) at least one optimal bracelet configuration (c*) adapted to the wearer, including determining the adjustment of the length of the bracelet on the basis of the at least one morphological data item (1; 2), the intermediate determining (E2) of the at least one optimal configuration of the bracelet including determining configuration data; and secondly, preparing (E3) the bracelet of the wearer according to an optimal configuration determined in the preceding step.

A plurality of bistable compliant links are pivotally attached to one another, each of the links having a compliant section and first and second rigid sections extending from the compliant section. The links are pivotally attached to one another via the first and second rigid sections, such that when the links are pivoted with respect to each other past a threshold position toward a closed position, the links are biased toward the closed position by forces created by the compliant sections, and when the links are pivoted with respect to each other past the threshold position toward an open position, the links are biased toward the open position by forces created by the compliant sections. The forces created by the compliant sections biasing the links toward the closed position and biasing the links toward the open position are caused by elastic deformation of the compliant sections.

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 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.
