SWISS gold filled mans watch size 16  signed Omega on the dial but we feel that it is not an Omega movement but a  well running generic Swiss movement with 15 jewels so we will just call it Swiss.   It’s a very good looking and crisply running watch with a perfect white dial and black Roman numbers surrounded by five minute dial in red.  Blued spade pointers and seconds dial at number six position.  Gold filled Fortune  case shows just normal wear and has three illegible initials on back within a frame.  54 mm diameter.  2 ¼”.  Hefty nice pocket watch.
