An electronic device includes a strap and a body. The strap includes a battery having a specific width, a specific thickness, and a specific length, a battery bracket having a size approximate to or greater than the size of the battery, seating the battery, and having at least one furrow formed around a part curved with a specific curvature, and a strap cover surrounding the battery bracket on which the battery is seated. The body has a side portion coupled to the at least one strap.

A watch case for a wristwatch including a watch middle, at least one strut for supporting the watch middle, the strut extending beyond the space occupied by the watch middle, a device for removably attaching a watch strap to the strut. The watch case further includes a member for fixing the strut or one of the struts to the watch middle, the removable attachment device being formed when the strut is fixed to the watch middle, and the fixing member includes a device for detaching the strut from the watch middle, configured to allow release of the strut from the watch middle without using tools, the strut being removably fixed to the watch middle.

The invention relates to a timepiece comprising a watch case formed by a middle closed by a back and a crystal, the middle being equipped with horns defining a space for receiving a bracelet strand, said timepiece comprising a sole arranged to rest against the back, the sole, the bracelet strand and the space between the horns comprising shaped elements arranged to cooperate by interlocking when the middle, the sole and the strand are assembled.

An exemplary wearable mobile device attachment article comprises a mobile device cover with a first face and a second face opposite the first face. An exemplary first face may be configured to provide access to the screen of a mobile device. A receptacle may project outwardly from the second face while a wearable article has at least one surface for frictionally engaging the mobile device cover.

A band configured to couple a device to a body of a user is disclosed. The band includes a first link comprising a recess defined in a body of the first link, a leaf spring positioned in the recess and comprising a tongue portion protruding from the leaf spring, and a second link coupled to the first link and comprising first and second lip portions extending away from a body of the second link and separated from one another by a gap. The tongue portion is positioned in the gap between the first and second lip portions, and the first and second lip portions engage the leaf spring to retain the second link to the first link.

The present disclosure discloses a smart watch, an operation control method and an apparatus therefor, the smart watch comprising a watch body and a watchband, wherein the watch body comprises a display screen and a system board, the system board comprising at least a microprocessor, a memory and a communication module. The watchband is configured to fix the watch body on a user's wrist. A biosensor is integrated on the surface of the wristband on the side adjacent to the user's wrist. As the watchband can contact directly with wrist side nerves, more accurate test results can be obtained, and the operational complexity is simplified. At the same time, by canceling the bezel design and performing a corresponding operation according to a touch operation detected in a functional region, the size of the smart watch is reduced and the comfort and flexibility during wearing is improved.

A portable electronic device is provided, including a main body, a C-shaped member, and a hinge module, wherein the main body includes a display surface and the C-shaped member includes an opening. The hinge module pivotally connects the main body with the C-shaped member. When the main body is situated in a first position, the main body covers the opening. When the main body rotates from the first position around an axis to a second position relative to the C-shaped member via the hinge module, the main body is away from the opening. An acute angle is formed between the axis and the display surface.

A sleeve for use in an assembly for coupling a wristworn device to a first end of a strap. The sleeve has a first end dimensioned to be received in the recess in the inner face of the first lug of a wristworn device, an inner cavity dimensioned to receive therein the first end of a conventional spring bar, and a retractor coupled to the sleeve for urging the first end of the spring bar towards the second end of the spring bar. The second end of the spring bar is coupled to the second lug, the spring bar is coupled to the strap, the first end of the spring bar is positioned in the inner cavity of the sleeve and the first end of the sleeve is coupled to the first lug. A removable retractor for use with a spring bar, which allows for the use of a plurality of spring bars and therefore, lends itself to widespread use and retrofitting of an assembly that couples a strap to a wristworn device, is also provided.

A wearable device is provided. A wearable device includes a display assembly having a display component, a network component, and a computing component, at least one reader coupled to the computing component and reading at least one of a barcode or Radio-frequency identification (RFID), a wrist band unit having a first wrist band unit and a second wrist band unit. The first wrist band unit is extended in opposite direction from the second wrist band unit, and accommodates the display assembly. The at least one reader is disposed to face in a tangential direction to a surface of the wrist band unit. The first wrist band unit has an attachment component and the attachment component is detachably attached to at least one of the display assembly and the second wrist band unit.

A survival wristwatch includes a timepiece and a wristband that include integrated survival kit features for assisting a user with various survival tasks. The wristband includes a cord, or paracord, winding or braiding around a strap. The strap is uniquely designed to integrate with the cord and provide adjustability of the wristband.
