At 46mm x 18mm and made from solid 316L stainless steel, this watch could hold double-duty as a close-quarters melee weapon. In contrast to both the Navigator and Medium Diver, the Marathon CSAR (or Pilot’s Chronograph Search And Rescue) is big, and it wears quite tall. Less weight, for less cash… And at 41mm x 13mm, it’s an easy daily-wearer to boot. Typically, you’d pay more for a more lightweight component on your ride, but the Marathon USMC Navigator comes in as the most affordable option worn by the team. And to anyone who has forked out the big bucks on a carbon fibre bike or component upgrades, shaving off every possible gram becomes an obsession. This is due to the unique Fibreshell material Marathon has used in the construction of the watch, and also because of its ETA F06 Quartz movement. If you are wondering why H3 tritium tubes are so important to the military, they provide a constant glow without needing to be changed by a light source. We wrote an in-depth article on tritium tubes here, and their functional appeal means they are present throughout the Marathon Watch catalogue.įor Cory, the Navigator has another feature that was of interest to him: it is light. This is in addition to the tritium tubes at each hour marker and on both the hour and minute hands.

The bezel on the navigator is bi-directional and contains a small H3 tritium gas tube in the pip at the top.

Neither of these watches have the chronograph function I found so useful, but they did have the bezel for overall ride time and all three withstood the same frigid conditions. My teammate Cory had been given the Marathon USMC Navigator to wear, and Nicki, the Marathon 36mm Medium Diver Automatic.
