I think that this chain is gold filled but did not test it. It is 12 inches long and has a cross bar and swivel, two decorative ends and a slide with carvings. The slide has lost its cork so it move freely. Nice looking Watch chain! The cross bar will go in a button hole and the watch on the swivel would be in your vest pocket. So that you could pull it out calmly and tell me the time!! You can't tell it but I did turn it over, it is exactly the same on both sides!
