A strap of the present disclosure includes a spring rod that includes a shaft member, and a strap main body that includes a plurality of decorative members coupled to each other and a connecting ring coupled to an end portion of the plurality of decorative members. The strap further includes a coupler that includes a spring rod insertion hole through which the spring rod is inserted, a fixing member insertion hole, and a connecting ring arrangement portion in which the connecting ring is disposed and that can be coupled to a watch main body of a watch by the spring rod, and a fixing member that connects the strap main body and the coupler by being inserted through the fixing member insertion hole and the connecting ring.

A device for attaching a bracelet or strap to a watch case includes a bar secured to the watch case by at least one horn and an insert integral with the end of the bracelet. The bar and the insert are complementary in order to cooperate by fitting one inside the other to form a removable assembly to make the bracelet interchangeable. The bar is formed by a cylindrical arbor having at least one flat portion. The flat portion cooperates by fitting with a housing made in the insert. The housing has a substantially rectangular opening for receiving the flat portion. The bar includes a control member for pivoting the bar from a first position A, in which the insert is positioned on the arbor, to a second position B, in which the insert is locked onto the bar.

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 in order to cooperate by fitting one inside the other to form removable assembly means able to make the bracelet interchangeable.

A device for carrying cordage includes a flexible, elongate and planar inner core having two opposite longitudinal sides and two opposite ends; and a cord wound around the two opposite longitudinal sides of the inner core along a longitudinal direction between the two opposite ends. The inner core and the wound cord together form an insert which has sufficient rigidity that facilitates full insertion of the insert into the sheath, strap, belt, or enclosure without bunching or kinking of the cord in a way that blocks a trailing portion of the cord from inserting into the sheath, strap, belt, or enclosure. A method for manufacturing the device is also disclosed.

A device for carrying cordage and survival tools including a flexible and elongate inner core, a cord wound around the inner core, and an outer sheath provided with an open end through which the inner core with the cord wound therearound is inserted. The outer sheath with the inner core and cord inside can be used as a watch strap for carrying thereon a watch case and a box disposed underneath the watch case for carrying survival tools. A method for manufacturing the device for carrying cordage and survival tools is also disclosed.
