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.

A wristwatch includes a main unit, a first design belt detachably attached to the main unit, an identifier that identifies the first design belt, a display device that displays the display content, a memory that stores the display content displayed on the display device, and a display control unit that displays the display content corresponding to the first design belt identified by the identifier on the display device.

Embodiments are directed to an attachment system for a consumer product and methods related to the manufacture thereof. In one aspect, an embodiment includes an attachment system including a band having an insert portion. The insert portion may include an aperture. The attachment system may further include a lug having a cavity and a friction element disposed at, and extending away from, an outer surface of the lug to define a protrusion. The attachment system may further include a pin and a retention member positioned within the cavity. The retention member may be configured to retain the pin within the aperture upon advancement of the pin past the retention member.

Disclosed is a wearable mobile terminal comprising a band unit, wherein the band unit includes a deformation part that is elastic and deformable; a plurality of segments enclosing the band unit, wherein the plurality of segments are movable to cover or expose a portion of the deformation part, the portion covered by the plurality of segments when all of the plurality of segments are arranged to be adjacent to each other and the portion is exposed when at least two of the plurality of segments are arranged to be spaced apart from each other; and a module unit configured to execute a specific function, wherein at least part of the module unit is disposed within the deformation part by being selectively exposed according to an arrangement of the plurality of segments.

A portable timepiece includes a case, a power receiving coil accommodated in the case, a bypass member configured to include a soft magnetic material, and a first band that is internally equipped with the bypass member, and that is transformable so as to dispose the bypass member between the power receiving coil and a charging device when charging is performed using the charging device.

A portable timepiece includes a case, a power receiving coil accommodated on a rear surface side in the case, a bypass member configured to include a soft magnetic material, and a first band that is attached to the case, that is internally equipped with the bypass member, and that enables the bypass member to be disposed between the power receiving coil and a charging device when charging is performed using the charging device.

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 electronic device is provided. The electronic device includes a housing including a first surface oriented in a first direction, a second surface oriented in a second direction opposite to the first direction, and a side surface at least partially surrounding the space between the first surface and the second surface, a base ring located adjacent to an edge area of the first surface and rotatably mounted on the housing, a first ornamental ring detachably mounted on the base ring and configured to rotate relative to the housing together with the base ring, and an interference member configured to perform a linearly reciprocating motion between a first position and a second position closer to the second surface than the first position, the interference member being located adjacent to the base ring and the first ornamental ring. At the second position, the interference member may be configured to maintain or fix the base ring in a stationary state relative to the housing by being at least in partial contact with the base ring. Various other embodiments are possible.

A watch can include a first watch band portion and a second watch band portion both configured to be coupled with a mechanical watch. The watch can further include a circuit board associated with a controller, the circuit board and controller being removably retained by a clasp. The circuit board and the controller can be electronically and operatively independent from the mechanical watch.

A sleeve and/or cuff holder apparatus is configured to prevent a sleeve or cuff of a shirt or other wearable garment from covering the face of a wearable device on a user's wrist, such as a watch, smart watch, wrist band, medical device, and/or other wrist accessory. Methods of using the same are further provided.
