A charm keeper assembly that includes a first and a second clasp member disposed at respective free ends of a strand member and a charm keeper body having a keeper body thickness and independently disposed adjacent to a clasp member and having a spring-loaded charm retention member at least partially housed within the keeper body. The charm retention member includes a retention surface spanning upwardly in a transverse direction away from an outer surface of the charm keeper body to a terminal end defining a keeper offset length when the spring-loaded charm retention member is in a fully extended position along a retention member translation path. The assembly also includes at least one charm member defining a lumen with a lumen diameter having a maximum length less than the offset length and the keeper body thickness, combined, when the charm retention member is in the fully extended position.

A wearable device includes a main body and a band body. The opposite sides of the main body are provided with a tail portion and a hook portion, respectively. An open groove is provided between the hook portion and other parts of the main body. One end of the band body is connected to the tail portion. The band body enters the open groove from an open side of the open groove and is folded back around the hook portion. The other end of the band body is fixed to a part of the band body, so that the band body is coupled to the hook portion, and the band body is adapted to fix the main body to a subject.

A wearable device includes a main body and a coupling member. The main body has a tail portion and a hook portion at two opposite sides respectively. One end of the coupling member is connected to the tail portion. A buckle hole of another end of the coupling member is for sleeving onto the hook portion to fix the main body to a subject.

Watch bands can employ clasps that are configured to ratchet. Due to this ratcheting, the watch bands can be adjusted which much smaller increments than traditional watch bands. A unique clasp configuration enables this ratcheting to be achieved without sacrificing aesthetic appeal or usability.

Connecting device allowing a releasable connection between a bracelet strap and a folding clasp including at least two articulated arms and two fastening portions capable of reversibly cooperating with each other. The connecting device includes a first connecting piece capable of being secured to the free end of the bracelet strap and a second connecting piece capable of being mounted on the fastening portion. The first connecting piece and the second connecting piece are configured to reversibly cooperate with each other between a first, open position allowing separation of the first connecting piece and the second connecting piece and a second, closed position in which the first connecting piece and the second connecting piece are locked together.

A wristwatch is provided incorporating one of a plurality of possible case embodiments, such as, without limitation, mechanical and electronic movements, and a novel ratcheting buckle and corresponding strap, whereby the user may incrementally adjust fitment of the watch via a ratcheting mechanism embodied between the ratcheting buckle and strap. In an embodiment, the watch comprises a strap including a first strap portion and a second strap portion. The first strap portion comprises a linear rack and a plurality of teeth embedded in the linear rack. The second strap portion coupled to a buckle wherein the buckle comprises a pawl configured to slideably engage up to each of the plurality of teeth of the linear rack as the first strap portion is inserted through a buckle aperture and translated therethrough.

A wristband locking mechanism for a wearable electronic device, a wristband, a wearable electronic device and a method of securing an article to a person. The wristband locking mechanism includes a clasp assembly with independently-operable spring-biased actuators such that the wristband locking mechanism cannot be unlocked using one hand. The use of sensors, processors, communication equipment and associated components within the wearable electronic device allows a caregiver to monitor one or more of location, environmental, physiological and activity data of a wearer of the device, while the requirement for two-handed operation for unlocking of the wristband locking mechanism provides a deterrent against intentional or unintentional removal of the attached article or wearable electronic device by the wearer.

A watchband assembly and a wrist-worn device having the same are provided. The watchband assembly includes a watch buckle, a watchband, a buckle tongue, and a rotating shaft for mounting the buckle tongue to the watch buckle, wherein the watch buckle includes a watch buckle upper cover and a watch buckle lower cover, the watchband and the rotating shaft are both arranged between the watch buckle upper cover and the watch buckle lower cover, and a fastener penetrates the watchband and is fixedly connected to the watch buckle to press and fix the watchband to the watch buckle. The lower surface of the watch buckle upper cover and/or the watch buckle lower cover is in contact with a human body when worn, such that the surface in contact with the human body when worn is smooth.

A watch band includes a connector including a first hole and a second hole arranged at opposite ends thereof; a first band connected to the first hole, and a second band connected to the second hole. The first band includes a first connection member connected to an end of a wearable electronic device, a free end section and an extension section connected between the first connection member and the free end section. The second band includes a second connection member connected to another end of the wearable electronic device. The free end section is extendable through the first hole to be fastened to the extension section by VELCRO-type hook-and-loop fasteners. The free end section is provided with loops, the fixing layer is provided with hooks engageable with the loops. The length of the watch band is adjustable via adjusting engaging position of the free end section and the fixing layer.

A clasp having deployant blades for a wristband includes at least two blades (1, 2), one movable blade (1) being articulated on a second blade (2) in the area of first extremities, the clasp being able to adopt (i) a first closed configuration, in which the movable blade (1) exhibits a first predefined form (C1) and extends in a continuous manner for its entire length, substantially along the surface of the second blade (2); and the second extremity of the movable blade (1) is maintained in position by the clasp, and (ii) a second, deployed configuration, in which the second extremity of the movable blade (1) is free, and the movable blade (1) is able to exhibit a second predefined form (C2), different from the first predefined form (C1), in order to optimize the passage surface for the hand of a person wearing the clasp.
