The invention concerns a device for attaching a bracelet or strap to a watch case, the device comprising, on the one hand, a bar secured to the watch case by means of at least one horn, and on the other hand, an insert integral with the end of the bracelet, wherein the bar and the insert are complementary to cooperate by interlocking or fitting with each other to form removable assembly means able to make the bracelet interchangeable. According to the invention, the bar is formed by a cylindrical shaft having a flat portion, the flat portion being arranged to cooperate by interlocking or fitting with at least one housing made in the insert, the housing having a substantially rectangular opening for receiving the flat portion, the shaft being telescopic to move from a first position A, in which the insert is positionable on the shaft, to a second position B, in which the insert is locked on the shaft.

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.

A wearable electronic device may include: a housing including a front plate, a rear plate, and a side member surrounding an inner space between the front plate and the rear plate, wherein the side member includes at least one portion including an external opening and an inner channel connecting between the inner space and the external opening: an insulating structure inserted into the inner channel; a conductive path partially embedded in the insulating structure, wherein the conductive path includes a first end exposed to the inner space and a second end exposed to the external opening; at least one printed circuit board positioned in the inner space and electrically connected to the first end of the conductive path; a display exposed through the front plate; and a band structure connected to the portion of the housing and configured to be mounted on a portion of a human body. The band structure may include a conductive rod movably inserted into the external opening and electrically connected to the second end of the conductive path, and an electronic component at least partially embedded in the band structure and electrically connected to the conductive rod. Other various embodiments may also exist.

A magnetism sensor equipped timepiece includes a case including a built-in magnetism sensor, a band for the timepiece, and spring rods that attach the band to bows of the case. The spring rods are each formed of a pipe, a pin, and a spring. The pipes and the pins are each made of a non-magnetic material, and the springs are made of a non-magnetic material having elasticity.

Watch case (1) comprising: a middle (2) provided with a blind hole (20); a first mobile horn (3) for fastening a strand of a bracelet, and provided with a through-hole (33); a first elastic element (31) exerting a force on the horn (3) that tends to push it back into a position with a widened lug distance (d); a push-button (5) traversing said through-hole (33) and engaged in the blind hole (20) in the middle, arranged so as to be able to slide between a locked position, in which the push-button (5) blocks the displacement of the horn (3), and a released position in which the displacement of the horn (3) into pushed-back position is possible, a second elastic element (52) exerting a force on the push-button (5) to push it back into the locked position.

The invention relates to a portable electronic device including a case and a watchband link attached to said case, the case comprising a pair of horns, between which is disposed a female electrical connector, the link comprising a male electrical connector disposed at the end of the link and adapted to make an electrical connection with the female electrical connector when the link is mounted on the case. According to the invention, each horn comprises a bar intended to come to be housed in an opposite housing of the watchband, the bars engaging successively in a guide groove and then in a locking groove formed in the link, the device comprising a manual actuation member for moving the bars into a retracted position.

A coupling member that is attachable to/detachable from a housing of an electronic device while making the housing wearable on a user's body, and an electronic device including the coupling member is provided. The electronic device includes a band member that is configured to come in contact with a user's body portion, a slide member that is mounted on the band member, and is bound to a portion of the housing in a state where the coupling member is mounted on the housing, an opening that is formed in the slide member, a locking member that is disposed on the band member, and a locking protrusion that is formed on a locking member. The locking protrusion appears to the outside of the slide member through the opening according to the reciprocating of the locking member, and the coupling member is bound to the housing.
