This neat item is vintage circa early 1900s. It is a pocket watch chain and is fashioned from 10k yellow and white gold filled metal. It has a really interesting box type woven link design and is stamped WF 1/40 10k RGP, which means I believe that 1/40th of the overall weight of this item is 10k rolled gold. It is in great condition and the only place it shows wear is the end on which you attach the watch where some of the plating has worn off, probably from taking the watch on and off. The chain measures 14 inches long and is 3mm wide.
