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.
