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 watchstrap including two separate strap sections, a first section including one or more holes in correspondence to which fastening a second section, to fasten the strap and the watch around a wrist. The strap includes a fastening system with a male part removably fixed to the first section through one of the holes to set a predefined width of the strap, and a female part, fixed on the second section and provided with a receiving seat for snap-engagement of the male part, for an automatic and pre-adjusted fastening of the strap around the wrist, the female part for releasing the male part, to open the strap. Also a fastening system for the strap of a watch and a watch comprising the strap with the corresponding fastening system.

A band is disclosed which attaches to a portable electronic device. The band includes a flexible length of material which forms a loop into which a pin is inserted. In one embodiment, the loop has an insert with a protrusion therein. The protrusion frictionally contacts the pin. In another embodiment the pin includes an elastomeric surface. The elastomeric surface may include O-rings between two pin portions such that the amount of the elastomeric surface extending beyond the pin may be adjusted. In another embodiment, the elastomeric surface includes a sleeve on the pin.

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 clasp for securing a first strap with a second strap includes a first clasp portion having a first frame member and a first set of magnets movable from a first to a second position, the first clasp portion adapted to be attached with the first strap; and a second clasp portion adapted to selectively connect with the first clasp portion, the second frame clasp portion having second frame member and a second set of magnets positioned in a fixed location within the second clasp portion, the second set of magnets positioned adjacent the first set of magnets when the second clasp portion is connected with the first clasp portion, the second clasp portion adapted to be attached with the second strap. When the first and second set of magnets create an attractive magnetic force therebetween in the first position and a repulsive magnetic force therebetween in the second position.

A connection structure includes: a connection pin that includes a first part and a second part between which a step is formed and that connects a first target and a second target by being inserted in an insertion hole; and a pin locker movable in a moving direction in a recess formed in either the first or second target. The pin locker has a pin engaging part that engages with the step of the connection pin and a pin insertion part. One of the recess and the pin locker has a first abutting part, and another has a first abutted part. When the pin locker is at a specific position and the first abutting part abuts the first abutted part, at least either an orientation or a position of the pin insertion part is limited such that the second part is allowed to pass through the pin insertion part.

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 strap for a wearable physiological monitor can be adjusted to a desired tension. The strap may include a buckle that retains a length of the strap as the strap is removed from and replaced to the wearable physiological monitor. In this manner, one or more straps may be removed and replaced without requiring readjustment of strap length for a particular user.

A connection structure includes: a connection pin that includes a first part and a second part between which a step is formed and that connects a first target and a second target by being inserted in an insertion hole; and a pin locker movable in a moving direction in a recess formed in either the first or second target. The pin locker has a pin engaging part that engages with the step of the connection pin and a pin insertion part. One of the recess and the pin locker has a first abutting part, and another has a first abutted part. When the pin locker is at a specific position and the first abutting part abuts the first abutted part, at least either an orientation or a position of the pin insertion part is limited such that the second part is allowed to pass through the pin insertion part.
