The concept of “mil-spec” is so frequently lobbed around the firearms industry as to be almost a parody of itself —bouncing back and forth between if its good enough for our warfighters … and made by the lowest bidder. Of course, weapons are not the only military equipment with rigorously detailed specifications. Among the other tools of soldiers and first responders, watches are so critical a staple as to be oft forgotten by most of us. However, a thriving and intricate watch culture exists among members of the defense and intelligence communities. From specific brands or models issued to members of particular units to individual timepieces worn by high-profile personalities or fictional characters, tactical horology has found its place in social media and pop culture. Above: Our test sample, a 41mm Marathon GSAR Type II with “Arctic Edition” dial and stainless steel link band. Even the typeface used for markings is dictated in the MIL-PRF standard. These discussions are often littered with a who’s who of practical and luxury watch brands: Seiko, Tudor, Breitling, Rolex, and more. But there is another name in watches that quietly sets the standard and has endured the ultimate test across nameless countries and campaigns — much like the operators who wear them. Enter Marathon. Founded in 1939, Marathon seemed fated from the beginning to take its place in the halls of military tradition. When asked how their connection to military efforts came about, they described it as “A right time/right place scenario. At the beginning of World War II, Marathon’s HQ was in the same building as the War Department. Then-President, Morris Wein, had discussions with the War Department about the immediate need to send durable wristwatches that could be synchronized to the Canadian battalions overseas in Italy. The rest is history.” The Qualified Product Database lists every wristwatch manufacturer that meets DoD performance standards. Marathon is the list. The need to supply frontline troops with combat-capable timekeeping did not end with WWII. In fact, it remained so critical a requirement that in 1964 the DoD released an official performance specification known as MIL-W-46374. The declared standards covered everything from the font used on the dial, to luminescence requirements, radioactivity warnings for said luminescent material, as well as tolerances for magnetism and resistance to shock, water, and scratching. The spec has undergone a series of changes over time, adding or adjusting requirements and outlining Type and Class categories for qualifying watches. The current iteration is MIL-PRF-46374G and, to this day, Marathon is the only watchmaker whose models meet the “G” standards. In fact, if you search Uncle Sam’s Qualified Product Database for a list of certified watches, Marathon is the list. The model shown in these photos is their 41mm GSAR, or Government Search And Rescue. Introduced in the 1990s, the SAR line was designed to meet the standards of Canadian professional search-and-rescue organizations, including water rescue. Models from the SAR line are submersible to 30ATM and sport a unidirectional rotating dive bezel. Handsome enough for a night on the town, tough enough for a day on the range, the GSAR’s automatic mechanism seemed unaffected by recoil. The case is 316L stainless steel and luminescence is achieved through both sealed tritium vials and MaraGlo paint. It’s currently in use by both Canadian and U.S. military units. Under the MIL-PRF standard, this watch is categorized as Type II, Class 4. Type II – Analog, long life (five to 10 years), maintainable, antimagnetic, water-resistant, high altitude, corrosion-resistant Class 4 – Mechanical movement, battery not required There are several versions of GSAR. This one is the Arctic Edition, which features a matte white dial that Marathon says was specifically implemented for cold weather operations where bright or snow-blind conditions may exist. We asked them if they had any other unique examples of mission-driven watch variants. The combination of sealed tritium vials and MarGlo paint ensures you can keep track of your timeline in any lighting condition. They provided us two: The Anthracite GSAR was issued for stealth during tactical night missions. The full 316L stainless steel case and movement are outfitted with a durable black anti-reflective Ion-Plating (IP) armor. Marathon introduced various models in the lineup to be lumed only with MaraGlo luminescent paint instead of tritium. This was done mainly to comply with military requirements where any amount of radioactive material was prohibited, such as on nuclear-powered submarines. While we can hardly claim to have truly tested this watch to its capability, we did have the opportunity to try it out for a couple of range days and training classes, including a man-tracking and surveillance exercise with Greenside Training. If you look carefully, you can also spot it on the author’s wrist during several episodes of the RECOILtv Podcast. Even the packaging is military grade — a gasket-sealed, clasp-lock hard shell with cut foam. We sought out some input from those who know this world better than us. Specifically, the former intelligence officer who now runs the blog Watches of Espionage — a fantastic read for anyone interested in watches worn by America’s military and intelligence elite. WoE Actual had this to say about Marathon watches: “Marathon stands as one of the last true analog watches still issued to forces in the U.S., Canada, and around the globe. In a community dominated by digital tool watches, the Marathon endures not out of nostalgia, but also because it meets the exacting requirements. The Marathon GSAR (Government Search and Rescue) in particular stands out as it was developed from the original SAR platform created for Canadian Search and Rescue technicians.” The high-visibility white dial was intended to combat snow glare in wintry weather, but we found it equally useful under harsh desert sun. Our sample GSAR would be just as comfortable in a boardroom as on the battlefield. Its rugged construction and timeless styling make it a nearly universal timepiece that embodies the most stringent requirements for hard use when the hour is upon us.
