The case also includes a manipulation member that can be manipulated by a user in order to move the second member between a locking position in which the members co-operate to maintain the pair of horns on the middle and a release position in which the pair of horns can be detached from the middle.

Disclosed is a wearable device, including: a connecting member, a device main body, a band body, a limiting clamping groove, an installation groove, and a limiting member; the device main body is detachably connected to a peripheral wall of the connecting member; the band body is connected to two opposite ends of the connecting member; the limiting clamping groove is provided at one of the connecting member and the device main body; the installation groove is provided on the other one of the connecting member and the device main body, a notch of the installation groove is provided opposite to a notch of the limiting clamping groove; and the limiting member is rotatably provided in the installation groove to have a locking position and an unlocking position, the limiting member is provided with a limiting clamping convex for snapping into the limiting clamping groove.

A device (1) for fastening a bracelet (2) to a watch case (3), at two pairs of horns (4), by a female connecting element (5) secured to the case (3) of the watch and a male element (6) secured to one end (20, 21) of the bracelet, these elements being complementary cooperate by fitting one into the other, while forming removable assembly capable of making the bracelet interchangeable. The male element includes a rod (7) connected to an end (20, 21) of the bracelet, and extending on either side of the rod, a ball-pawl (8) and first (70) and second (80) cylindrical shouldered portions arranged concentrically around each ball-pawl, each ball-pawl and each cylindrical shouldered portion being arranged to cooperate respectively with blind housing (50) and groove (51) proximate to the blind housing, and forming the female connecting elements on inner areas of the two pairs of horns.

Systems may include a watch band, a watch body comprising at least one image sensor configured to capture a wide-angle image, a coupling mechanism configured to detachably couple the watch body to the watch band, and at least one biometric sensor on at least one of the watch band or the watch body.

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.

A necklace adapter for use with a smart watch is described. The necklace adapter generally includes an adapter base for connection to the smart watch and a retainer assembly for releasable attachment to a necklace of a user. The retainer assembly includes a hollow lower stem attached to the adapter base and having a first clasp member and a solid shaft, movably mounted within the lower stem, having a second clasp member. The solid stem and second clasp member are movable from a first closed position forming a closed loop with the first clasp member to a second open position spaced from the first clasp member. A spring is provided to bias the solid stem and second clasp member to the first closed position. In one embodiment, the retainer assembly is connected to the adapter base by a ball joint connection to adjust the position of the smart watch for the convenience of the user.

Embodiments of a watch can include a watch having an analog watch face, a first watch band portion, a second watch band portion and an analog watch face. The watch can include a digital clasp having a digital display and a circuit board associated with a controller.

The invention concerns a device for attaching a bracelet or strap to a watch case, the device comprising on the one hand, at least one horn integral with the watch case, and on the other hand, an insert integral with the end of a bracelet strand, wherein the horn and the insert are complementary to cooperate by interlocking with each other to form removable assembly means able to make the bracelet interchangeable. According to the invention, the insert includes at least one stud subjected to the action of elastic return means, said at least one stud being arranged to cooperate with at least one housing in the horn, the horn including a control member projecting radially with respect to the horn, in order to move the stud from a deployed position in which the stud holds the strand on the horn, to a retracted position in which the strand is released from the horn.

An attachment system of a wearable electronic device includes a removable module. The removable module includes a locking mechanism comprising a first portion having a substantially planar top surface and second portion that comprises a substantially non-planar bottom surface. The first portion and the second portion are coupled together. The locking mechanism also includes a first spring mechanism coupled between the first portion and the second portion. The first spring mechanism causes the first portion to be biased away from the second portion. The locking mechanism also includes a second spring mechanism. The second spring mechanism causes the substantially planar top surface of the first portion to be biased substantially flush with respect to the removable module and also causes the substantially non-planar bottom surface of the second portion to be biased proud with respect to the removable module.

Embodiments of the present disclosure provide a locking assembly for an attachment system of a consumer product. More specifically, embodiments of the present disclosure are directed to an attachment unit that is configured to be inserted and removed from a housing of a consumer product. The attachment unit and/or the housing include an expansion component or other such locking assembly configured to releasably secure the attachment unit within the housing.
