Hamilton GG-W-113 Field Watch

Sold for: $600.00

The History

Since World War II the US armed forces have issued specifications for wristwatches to be produced for soldiers, airmen, sailors, and more. Of these specifications, the GG-W-113, which was first issued on June 6th, 1967, became the staple of the service issued watch models and as a result it saw production for almost 20 years. While the full specification can get a bit technical (and boring) it basically breaks down to seven key features that the military was looking for. Those features were

  • A mechanical movement with an accuracy of +- 30 seconds per day
  • 15 Jewels
  • A hacking mechanism
  • Shock resistance (must survive a fall from 4 feet onto a wooden block)
  • Waterproofness
  • Luminous Hands (using Tritium)
  • Antimagnetic
  • Minimum of 36 hour power reserve

Several companies answered the call to produce these watches with examples from Hamilton, Benrus, Marathon, and Glycine Altus. The GG-W-113 is also very similar to another military issuee watch, the MIL-W-3818, and while they share a similar appearance, the GG-W-113 was issued to pilots whereas the MIL-W-3818 was issued to ground troops.


The Reference

The GG-W-113 is an extremely simple watch that was designed for a singular purpose and this simple design and construction allows it to complete its goal rather well. The dials are highly legible and useful, featuring inner 24-hour markers, the cases are very durable, featuring a one-piece construction and Parkerization, and the lugs are fixed. If there was ever a better representation of a tool watch I don’t know what it is. These watches have become so archetypal that many modern brands produce a homage to this watch including Hamilton themselves. At roughly the same price for the homage or the original, our choice is the original all day.


The Case

The 34mm steel case is in great condition and shows little signs of wear. The dark matte appearance of the case is due to a process called Parkerization, which protects the steel from corroding through the application of a chemical phosphate conversion. As mentioned above, the case is a solid one piece construction which access to the movement being achieved through the front of the watch. The case back features the various military identification markings including a marking that bears the production date of June 1982.


The Dial and Hands

The black dial is in excellent condition with no major flaws to note. The tritium lume has aged to a wonderful caramel color. The handset is correct for the watch and is showing its age a bit more than the dial but condition is still very good.


The Movement

This watch features a hand wound Hamilton Calibre 649 which is a branded ETA 2750 movement. The watch is running and the service history is unknown.

    Was this watch tested for accuracy and does the hack work?
