A device for finely adjusting the length of a bracelet inserted between two elements of the bracelet and includes an outer part attached to one, an inner part attached to the other and to slide in the outer part parallel to the longitudinal direction of the bracelet, causing the length of the bracelet to be varied, and a stop arranged to limit the travel of the inner part relative to the outer part so the bracelet cannot be extended beyond a maximum length. The outer part includes a wall having an immobilization hole on its inner side. The inner part includes a pivoting lever with a first end biased by a spring toward the outer part wall, permitting the first end to engage the immobilization hole, immobilizing the inner part relative to the outer part. The inner part has a control member permitting manual control of the lever.

The invention relates a folding buckle clasp for a wristlet allowing different radii of curvature of the clasp when it is in the closed position, said clasp comprising a first blade (1) arranged to rest entirely on the wrist of a wearer of the clasp and a second blade (2) arranged to rest entirely on a wrist of a wearer of the clasp, the first and second blades (1, 2) being articulated with respect to one another at a first end (3), the free end of the first blade (1) having an articulation (4) for articulating a first strand (5) of a wristlet or a third blade (6), the free end (7) of the second blade (2) being arranged to receive a second strand (8) of a wristlet. Each blade (1, 2, 6) is composed separate and interchangeable independent links (10) arranged so as to create a pivoting angle between two successive links (10) of between 20° and 50°.

A wristlet clasp (100), of the folding buckle type, including first and second hinged blades (1, 2) between a closed wearing position and at least one open position, the first blade carrying a member for fastening a first wristlet strand, the second lower blade being connected to a loop (3) at its second end, the loop defining a passage for a second wristlet strand and carrying a stud (31) intended to be inserted into an adapted hole in the wristlet strand to define a point for anchoring the latter to the clasp. A locking member (12) holds the first and second blades in their closed position. A carriage (4) is connected to the second end of the second blade and slides in the loop switching from first and second indexed positions to define at least two predefined positions associated with a predefined useful length of the wristlet.

A wristlet clasp (100), of the folding buckle type, including first and second blades (1, 2) hinged relative to each other, the first blade (1) further including locking means for holding the first and second blades (1, 2) in their closed position at its second end, and the second blade (2) carrying a member for fastening a first wristlet strand at its second end. The first and second blades are hinged together by movable blades (3, 4) by a first of their respective ends, the hinged blades being connected to the first and second blades via a first hinge (A1) and a second hinge (A2), the hinge (A1, A2) being angularly delimited by stops respectively formed on the first end of the first and second blades and on the second end of the movable blades so as to define two predefined wearing positions depending on the size of the wrist.

A folding clasp for a wrist watch comprising a first bracket (3) and a second bracket (4), wherein the first bracket (3) has a first securing mechanism (6) for securing a wristband or a watch housing of the wrist watch, wherein the second bracket (4) has a second securing mechanism (7) for securing the wristband (2) of the wrist watch, wherein the first bracket (3) and the second bracket (4) are moveably connected to one another, such that the first and the second brackets (3, 4) can be moved relative to one another between an open state and a closed state of the folding clasp (1), wherein the folding clasp has a locking mechanism (9) in order to retain the first and the second brackets (3, 4) in the closed state, wherein the second securing mechanism (7) has a protruding pin (74) which is designed to be guided through the wristband (2) in order to secure the wristband in various axial positions in the second securing mechanism (7), wherein the second securing mechanism (7) has a blocking means (8) which is designed to retain the distal end of the pin (74) guided through the wristband (2) such that the wristband is blocked on the pin (74) in the open state of the folding clasp (1).

A biological information measuring device includes: a case unit; a first band that is a member connected to a first end portion of the case unit; and a second band that is a member connected to a second end portion of the case unit at the side opposite to the first end portion. When a direction from the first band toward the second band is Y axis, a direction orthogonal to the Y axis in a plan view seen from a thickness direction of the case unit is X axis, and when a width of the first end portion in the X axis direction is a and a width of the second end portion in the X axis direction is b, the case unit satisfies a relation a<b.

This application provides a wearable device. The wearable device includes a bearing body and a Bluetooth headset. An accommodating slot is disposed on the bearing body, a first locking component is disposed on the Bluetooth headset, and a second locking component is disposed on the bearing body. The Bluetooth headset is accommodated in the accommodating slot. The first locking component is locked with the second locking component. The Bluetooth headset includes an operation portion. The operation portion is configured to: unlock the first locking component and the second locking component, and push the unlocked Bluetooth headset out of the accommodating slot. The wearable device in this application may directly accommodate the Bluetooth headset, to provide more convenience to a user.

A timepiece component having a first part and a removable cap which can adopt a fastening configuration and a free configuration. The first part comprises at least one first latching member and a movable lock. The cap comprises at least one first assembly member designed to cooperate with the first latching member of the first part, and a second assembly member designed to cooperate with the movable lock. In the fastening configuration, the first latching member of the first part and the first assembly member of the cap are in engagement. The movable lock is in engagement with the second assembly member of the cap. The cap is fastened in a locked manner to the first part. In the free configuration, the movable lock occupies an open position in which it releases the second assembly member of the cap and allows the cap to be separated from the first part.
