An end piece arranged to be detachably fixed to a bar, the end piece including: a groove intended to house the bar; a rotating part able to pivot about an axis parallel to the bar between a locking position, in which the rotating part prevents the bar from leaving the groove, and a release position, in which the rotating part allows the bar to be respectively introduced into or extracted from the groove; and a locking mechanism arranged to block the rotation of the rotating part. This end piece can be handled by the user, who can fix it to a bar and detach it from the bar without requiring any tooling.

An end link for securing a watch strap on a watch case including a connecting piece of a wristband, the watch case having a pin. The case has a longitudinal slot delimited by two support surfaces parallel to a main plane. The connecting piece has a lateral face which includes a guiding groove arranged to cooperate in a complementary manner with the pin, and the connecting piece has a lock with a slide catch arranged to cooperate with the slot in a locking position, towards which the slide catch is moved by elastic return belonging to the lock. There is unlocking portion arranged to be operated directly by a user to move the slide catch away from said slot of the case. The guiding groove is curved so that the slide catch is firmly maintained against one of the two surfaces in the locking position.

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.

Techniques are described herein for a wearable device that is configured to prevent unauthorized removal and to facilitate detection of unauthorized removal attempts or tampering with a band of the device. The wearable device includes one or more circuit systems, each of which is configured to conduct an electric current. Attempts to remove the device cause components of one or more of the circuit systems to break/fail, which disrupts the electric currents of the broken circuit systems. Such electric current disruptions are detected by the wearable device as evidence of an unauthorized removal attempt or tampering with the device band. The wearable device may include a hook-based latching mechanism or a rod-based latching mechanism. According to various embodiments, the wearable device is engaged with or disengaged from around a limb of a wearer responsive to an engage or disengage instruction from an authorized user of a client device.

A band includes a spring rod including a first operation lever linked to a first slider and a second operation lever linked to a second slider, a first piece including a first portion, a second portion, and a linkage section that links the first portion and the second portion to each other, the first piece having a first recess in each of the first portion and the second portion, and a second piece disposed between the first portion and the second portion, the second piece having a second recess. The spring rod is disposed in a closed curve that is the combination of a left first recess, a right first recess, and the second recess in the side view viewed in an axial direction of the spring rod. The second piece is disposed between the first operation lever and the second operation lever.

This application discloses a watchband clasp, a watchband, and a wearable device. The watchband clasp (1000) includes a first fastener (1), a second fastener (2) rotatably mounted on the first fastener (1), a cover plate (3) rotatably mounted at an end that is of the second fastener (2) and that is away from the first fastener (1), a hook member (4) slidably mounted on the cover plate (3), and an elastic member (5) mounted between the cover plate (3) and the hook member (4). The elastic member (5) can enable the hook member (4) to maintain a clamped state with an inner wall of a hook hole (11). The cover plate (3) is provided with a first accommodation slot (35) used to accommodate the first fastener (1) and the second fastener (2).

A wristwatch having a watch case that rests against the radial side of a wearer's wrist is provided. The wristwatch includes a radial watch having a rigid band with a first and second end that forms a gap. A watch case is secured between the ends forming a closed loop. The rigid band is monolithic and sized in such a way that the watch case is disposed on the radial side of the wrist when worn. The watch case includes a face that can be oriented towards the wearer for convenient viewing. In one embodiment, the band includes padding on an interior side.

An identification bracelet includes a wristband securable to a wearer. The wristband includes a plurality of openings for receiving a locking rivet and one or more openings for receiving one or more color-coded pins, a housing attached to the wristband, the housing having a pair of lugs with a slit, each lug extending from each side of the housing and adapted to receive the corresponding ends of the wristband inserted into the corresponding slits. The housing comprises a snap-on cover with at least a portion of the cover being transparent, a base, and a waterproof gasket insertable into the base. The snap-on cover is configured to be snapped on the base thereby creating a hermetically sealed waterproof structure. The housing also includes an information tag insertable into the housing and visible through the transparent portion of the housing.

A watchband with conductive function of a bracelet includes a first watchband and a second watchband. The inside of the first watchband is provided with an electrical stimulation module. The electrical stimulation module includes a signal strip arranged along the length direction of the first watchband, a circuit board connected to the signal strip and an electrode connected to the circuit board. The electrode is located at an end of the first watchband away from the dial.
