The head portions of the staple elements are positioned adjacent and end edges of the tubular link elements when the staple elements are assembled in the bracelet and the head portions are formed in enlarged dimensions to conceal the end edges of the link elements and to better retain the link elements on the bracelet when the bracelet is constructed with a plurality of rows of link elements.

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.

Abstract: The disclosure sets forth a different annular link as the building element; instead of using a split annular link of a 3:1 ratio of link inner diameter to major wire diameter, the link has substantially thinner annulus for forming the rope chain, an annulus that requires an over 5:1 ratio of inner annulus diameter to major wire diameter. The presently preferred ratio is between 5.2 and 5.7:1. It is possible to use even thinner annuluses, i.e. having greater ratios, e.g., 7.2-7.7:1 with even greater weight savings (approximately 35%), or other even greater odd-numbered ratios of inner annulus diameter to major wire diameter (e.g. 9.4-9.9:1). Thus, while there is no theoretical limit, there is probably a maximum practical upper limit to the ratio of inner annulus diameter to major wire diamater.

Abstract: A watchband is comprised of a plurality of interconnected segments of generally helical shape. The segments are formed of tubular metal rods which may be composed of a noble metal alloy, a copper alloy or stainless steel. The use of tubular metal rods as opposed to solid metal rods results in a reduction in materials costs and a lighter weight watchband. The watchband is manufactured by winding a tubular metal rod on a mandrel into a generally helical shape, cutting the helically-wound tubular metal rod to predetermined lengths, and connecting together the lengths in lengthwise juxtaposition so that the coils of one length partly overlie the coils of adjoining lengths to thereby form a watchband comprised of interconnected tubular metal rod segments. By using tubular as opposed to solid metal rods, the annealing process normally required in order to wind the rod into helical shape can be eliminated.
