※ This item is a limited-time listing until January 7th due to my work schedule, and will be removed on the evening of the 7th. This is a GG-W-113 military watch manufactured in 1972 and supplied to the US military. It has been overhauled at a watch store in Ueno, Tokyo in 2024, so it is ready to use immediately. The "GG-W-113" military watch, famous for being supplied to the US military during the Vietnam War, was produced for approximately 20 years from 1967 to 1986. The back cover is engraved with "DECEMBER 1971," indicating that it was manufactured in 1971. Since there is no manufacturer's marking, it is believed to be made by Benrus or Hamilton. While the shape of the one-piece case is similar to the "MIL-W-3818B" supplied to the Army, this "GG-W-113" is for pilots. It has more jewels than the Army version and is a military watch designed to be repaired and used for a long period, rather than being disposable. It features a matte black dial with a 24-hour full Arabic numeral index, providing high visibility and functionality. The case has no noticeable damage, and the engraving on the back cover is still clear, making it in very good condition considering it was manufactured 54 years ago. In the images, the spring bar at the lugs is replaced with a thin bar that is fixed in place. This was taken from another watch, and can be removed by pushing the thin bar through the lug hole. Brand: Believed to be Hamilton or Benrus.
