Art Deco is where it's at, and this rare Illinois USA made high grade watch from the 1930s is a great find.  The case and case back serial numbers all match, the dial and hands have a fantastic patina, the the case has very little wear showing off its deco engravings with great detail.  Illinois wrist watches are in very high demand as so few were produced along with the fact that they are extremely high quality.  The watch is running well and comes on a new medium dark grey leather strap which rounds out the entire piece to make a stunning combo.  The case measures 34mm long and 28mm wide.  This watch runs on the 21 jewel highest grade Illinois caliber 601.  For more information please google adamvintage.  Thank you.
