A jewelry securement device may include a band having a first end and a second end. A female retainer may be coupled to the first end, and a male retainer may be coupled to the second end of the band. The female retainer may comprise an aperture. The male retainer may comprise a shape that is complementary to the shape of the aperture, and portions of the male retainer may be inserted into the aperture of the female retainer to position the first end and second end proximate to each other. Preferably, the band may be movable between a closed position in which portions of the male retainer are inserted into the aperture of the female retainer, and an open position in which portions of the male retainer are separated from the aperture of the female retainer.

Embodiments of the present disclosure provide a multi-membered bracelet. The palm bracelet includes three members connected by connecting chains. In some embodiments, one of the three members is configured to rest within the space between the thumb and index finger. In some embodiments, one of the connecting chains is configured to rest within the space between the thumb and index finger.

A strap for a wearable device configured to secure to a portion of a body of a user can include a base and a plurality of strap members secured to portions of the base. In some implementations, the base is made of a first material and each of the plurality of strap members are made of a second material, the first material being more pliable than the second material. In some implementations, the base includes a plurality of openings spaced from one another along a length of the base and a plurality of stems. In some implementations, each of the plurality of strap members is a channel secured to one of the stems. In some implementations, the first material includes at least one of rubber and silicone and the second material is a metallic material.

A timepiece part according to the invention includes: a substrate; and a first coating configured from a material containing cobalt as a primary component, and 26 mass % to 30 mass % of Cr, and 5 mass % to 7 mass % of Mo. The first coating has a surface with a percentage surface area increase of 0% to 1.2% as measured by atomic force microscopy against a reference flat surface.

A single-section, rolled band bangle bracelet configuration in which a squeezing force via the thumb of a wearer's hand on one end of the band and via a finger of a hand on the opposite end serves to receive, grasp, and thereafter release the bracelet in connection with its wearing.

Hinged bracelet, for a watch or piece of jewellery, comprising an alternation of H-shaped links comprising side pieces forming the side ends of this bracelet, and central links, hinged to each other by arbors formed by pins or screws, wherein at least one central link is a decorated link comprising a removable surface shell arranged to be placed on a base which includes at least a first guide member and a second guide member both substantially of revolution respectively about a first axis and a second axis parallel to and distinct from one another, and arranged to receive these arbors, and the surface shell of each decorated link is surrounded and protected on either side of its width by the side pieces of the H-shaped links.

A bracelet or flexible band comprised of a flexible member that on one end is interconnected to a knife and on another end, is connected to a sheath that selectively receives the knife in the locking fashion. When needed, the knife is rotated within the sheath to facilitate release thereof from a lock that is integral with the sheath. Once removed from the sheath, the knife can be used for self-defense, cutting rope or cord in an emergency situation, or for general utility cutting tasks.
