A pivot chain end for a jewelry is provided in the present embodiment. The pivot chain end has a 360 degree linking mechanism for chains having jewelry items which helps in arresting the improper fall issue of the necklace when worn by a wearer. The pivot chain end includes an eyelet which is circular in shape linked with a back chain having an abutted cylindrical portion with a through hole and a metal disc having three flat flanks and one curved ridged side, wherein the metal disc allows the screw to pass through within the disc and connect the eyelet, through a partially threaded body on the screw, thereby securing the metal disc with the eyelet and enabling the eyelet to freely rotate 360 degree axially as per movement of the back chain.

A modular accessory apparatus includes a body component and a housing component. The body component has a first end and a second end, wherein the body component has a curvature such that a cap forms between the first end and the second end along the direction of extension of the curvature, and the first end has a connector. The housing component modularly couples to the connector. The housing component has a housing body, a coupler component, and a gateway block. The housing body has an opening, and the coupler component is disposed in the housing body. The gateway block is disposed in the opening, wherein the gateway block has a through-hole corresponding to the coupler component. The coupler component receives the connector via the through-hole, and the through-hole of the gateway block limits the displacement movement of the connector along a coplanar direction to the direction through the through-hole.

A stretchable watch band can include braided strands that provide a comfortable fit around the wrist of the user. The watch band can stretch and conform to the user based on the elasticity within each strand and based on the ability of the strands to move relative to each other. End sections of the watch band can include attachment elements that securely connect the watch band to a housing of the watch. The end sections can be configured to releasable connect to the housing in a manner that is reliable and easy for a user. Additionally, the watch band can provide a smooth transition from the size and/or shape of the housing to a size and/or shape of a continuous section of the watch band. Additionally, the watch band can conceal portions thereof other than the braided strands when connected to the housing of the watch.

A set of watch straps include a first strap, the first strap including a first band, a first adapter, and a first lug connected in series, and a second strap, the second strap including a second band, a second adapter, and a second lug connected in series. The first lug is configured to slide into a first strap receiving groove of the watch, and the second lug is configured to slide into a second strap receiving groove of the watch. At least one of the first strap and the second strap is reversible.

A lock mechanism includes a chain component and a lock connector component. The chain component has a head portion at one end. The lock connector component has a button portion, an accommodating space, and an opening disposed on a side adjacent to the button portion, wherein the opening space connects to the accommodating space. When the button portion is operated in a pressed state, the button portion is configured to block the head portion from entering or exiting the accommodating space via the opening. When the button portion is operated in a depressed state, the button portion is configured to allow the head portion to enter or exit the accommodating space via the opening.

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.

A charm and clothing attachment device includes a main body having a hook portion, a moveable arm and a central aperture. An elongated shaft having a sharp tip along a distal end extends outward from the main body. A receiver having a cavity is removably connected to the elongated shaft. One or more charms, each having a loop portion are suspended from the hook portion of the main body.

An attachment strap for a wearable electronic device is disclosed. The attachment strap attaches the wearable electronic device to a wearer, and may attach to a wrist of a wearer. The attachment strap includes two bands which attach to a clasp. The clasp operates in an open and closed configuration. When in the closed configuration, the clasp may not present a visible indication of its mechanism.

An attachment device is provided for two elements of a watch band to allow the two elements to be hooked into place or unhooked. The first element includes at least one bar on one of its ends. The second element includes two grooves, each including a longitudinal opening respectively opposite one another, and one of the two elements can move from an unhooked position. One of the elements is oriented in a predetermined angular position in relation to the other element, to a hooked position, in which the two elements are coplanar after a rotation of a predetermined angle of one of the two elements in relation to the other so that each groove is articulated on the bar to hold the two elements hooked to one another.

Disclosed are various examples of a jewelry catch. The jewelry catch can include a base eyelet comprising an anchor eye, a pivot eye and a bar that connects the anchor eye to the pivot eye. The jewelry catch can also include a double eyelet that includes a catch eye and a jewelry eye. Further, the jewelry catch can include a male clasp that includes a hook protruding from the male clasp and configured to slide into a channel shaped to receive the hook. Likewise, the jewelry catch can include a female clasp that includes a channel shaped to receive the hook, thereby securing the male clasp to the female clasp through friction between the hook of the male clasp and the channel of female clasp when the jewelry catch is in a closed position.
