Antique pocket watch chain, 10 1/4 inch chain, 11 3/4 inches with end links.

First five photos shows the chain on on side, then next 7 photos shows the chain flipped on the other side.  Last photo shows it measured.

Some plated wear seen, chain is not magnetic.  Chain has gold underneath the plating (believably brass).  Has nice patina.  

The visible eye can see a repair was done on one side using a silver colored link.  Some wear seen on other side of chain on 3 circle connection.  I only see wear on chain itself with a loupe or with magnified photos.
