Abstract: The invention relates to an unfolding bracelet clasp, in particular a watch bracelet, formed of two strands (A) and (B), comprising a metal plate (10) whereof one end is coupled with an articulation (11) at the bracelet strand (A) free end and a lever (12) whereof the pin (13) is mounted at the plate (10) other end. Said lever (12) comprises a U-shaped part whereof the legs extend on each side of the bracelet forming at their ends hooks (18) designed to be urged in engagement, when the bracelet is closed, with the ends of a spring box axle (20) transversely housed in the bracelet strand (A) at some distance from the articulation (11) substantially equal to the plate (10) length. The length of the bracelet is adjusted by a dog point (19) engaged in a suitable hole of the bracelet strand (B).

Abstract: A bracelet for the jewelry and watch making industry, includes rectangular elements connected in a flexible manner by oval links to form several parallel rows adjacent each other. The elements of adjacent rows are also connected with each other by oval links. Each element includes an upper plate and a bottom plate having cutouts that receive the free ends of pillars protruding from the upper plate. The links are of a sufficient dimension to embrace one pillar each of adjacent elements with sufficient play in the longitudinal and transverse direction of the plate, a vertical play being assured by the height of an abutment that keeps the upper plate and the bottom plate at an appropriate distance from each other.
