Disclosed is a clip for a bracelet and/or a necklace. The clip in a closed state having a through hole (402) allowing the clip to wreathe an elongated member of a bracelet and/or necklace. The clip comprises: a first part (420) and a second part (430), the first and second parts being connected by a hinge (401); and a first resilient element (460) arranged in the second part. The first resilient element comprising a first gripping surface (451) for frictionally gripping a surface of the elongated member. The second part comprises a cavity (443) extending in the radial direction, the first resilient element comprises a first resilient part (460) arranged inside the cavity and a second resilient part (470) arranged outside the cavity and extending in the radial direction from the cavity into the through hole. The cavity is configured to secure the first resilient element in said second part.

The present utility model discloses a watch frame, which is provided with a groove for mounting a dial, and the inner wall of the groove is provided with an elastic clip strip for elastically clamping the dial. The beneficial affected areas are below: An elastic clip strip is set in the groove of the watch frame, due to flexibility of the elastic clip strip it is compressed when the dial is installed so that the dial can be easily mounted into the watch frame. The dial can be clamped in the watch frame firmly. When disassembling, the dial can be removed from the watch frame by pressing the dial in downwards motion which saves time and labor and does not need any auxiliary tools.

Disclosed is a clip (100) for a bracelet and/or a necklace. The clip in a closed state having a through hole (102) allowing said clip to wreathe an elongated member (301) of a bracelet and/or necklace. The clip comprises: a first part (120) and a second part (130), the first and second parts being connected by a hinge (101); and a resilient element (150) arranged in the second part. The resilient element comprising a first gripping surface for frictionally gripping a surface (151) of the elongated member. The resilient element being spaced apart from the first part. The first part comprises a rigid second gripping surface (121, 122) for gripping a surface of the elongated member, and the resilient element and the rigid second gripping surface allows the clip to be releasably secured at selected positions along the elongated member and allows said clip in a closed state to be movable along the elongated member, on which it is positioned by exerting a force in the axial direction.

A bracelet has a metal wrist piece in an arc of a user's wrist, T-bars implemented on opposite ends, each T-bar comprising a round bar of a length substantially the width of the body of the wrist piece, spaced apart from the body of the wrist piece by a T element, a first compound strap of flexible material with a through passage at one end in the direction of the width, a central slot opening into the passage, and a male snap element presented on a surface of the compound strap proximate an end of the strap opposite the through passage, and a second compound strap like the first but with a female snap element. The bars at the ends of the body of the wrist piece are inserted into the through passages through the slots into the through passages, joining the straps to the wrist piece on opposite sides.

Jewelry devices and assemblies for adjusting the appearance of jewelry as worn. The assemblies include a clip having first and second shell pieces pivotally coupled together with a hinge disposed within an interior volume defined by the shell pieces. Gripping members defining gripping surfaces are affixed to interior surfaces of the shell pieces and cooperate to hold in place one or more portions of a necklace, bracelet, anklet, and the like. In some examples, a portion of an elongated member of a jewelry article, such as a necklace chain, is couplable to a terminal extending from one of the shell pieces.

Strap arrangement comprising a first strap portion comprising a plurality of strap engaging structures, each strap engaging structure defines a size of an opening of the strap arrangement; a flexible second strap portion comprising at least one locking piece, the locking piece comprising at least one locking piece engaging structure for being aligned with at least one of the strap engaging structures; and at least one magnet adapted to force the locking piece engaging structure against at least one of the strap engaging structures by a magnetic force.

A biometric sensor for detecting wrist blood vessels in a wristband or wristwatch. The sensor has a substrate and an array of thermal detectors arranged on the substrate. Suitable detectors include near infrared photodetectors or temperature detectors. Advantageously, the array has printed organic components on the substrate.
