History behind the watch:
Exceptionally rare Marathon GG-W-113 Navigator watch. Being navigator watches, they are issued to Pilots in the USAF back in the 1980s. Unlike the more commonly found GG-W-113 made by Hamilton and Benrus, these Marathon has the H3 and radioactive symbols on the dial. All cased in an uncommon shaped stainless steel case. These cases were normally found on British issued watches.
