Today we're looking at a vintage military classic, The Hamilton gg-w-113 government issued Vietnam War pilot's watch. This model was spec'd by the U.S. government for pilots in the U.S. military. The case is parkerized steel, for toughness and anti-glare. The dial is a sterile dial with tritium lumed markers and 24 hour numerals. It's manual wind, with hacking seconds. Enjoy!
