Marathon 41mm SSNAV Pilot's Quartz Arctic Tritium Type II WW194001SS-0503

The Marathon 41mm SSNAV Pilot’s Quartz Arctic Tritium Type II (ref. WW194001SS-0503) is a modern military navigation watch engineered for pilots, parachutists, and operational environments where reliability and legibility matter more than luxury finishing. Based on Marathon’s original Steel Navigator platform developed with Kelly Air Force Base in 1986, the Arctic edition introduces a high-visibility white dial specifically designed to improve readability in bright daylight and snow-covered conditions. The fully brushed 316L stainless steel case, asymmetrical military-style profile, and bi-directional 12-hour bezel give the watch a distinctly functional appearance that feels closer to issued equipment than a traditional civilian pilot watch.

Powered by the Swiss ETA F06.402 HeavyDrive-PreciDrive quartz movement, the SSNAV delivers exceptional accuracy of approximately ±10 seconds per year while remaining highly resistant to shock and vibration. The watch features tritium gas tube illumination on the hands and markers for constant low-light visibility without external charging, along with a sapphire crystal, screw-down crown, and 100 meters of water resistance for real-world durability. Unlike many modern pilot watches that lean heavily into vintage styling or luxury presentation, the SSNAV Arctic is unapologetically utilitarian—lightweight, highly legible, and purpose-built for operational use.
