Marathon 41mm SSNAV Pilot's Auto Arctic Tritium Type II WW194029SS-0503

The 41mm Arctic Steel Navigator Automatic (Arctic SSNAV AUTO) is part of the Steel Navigator squadron that features a self-winding automatic movement. Equipped with Swiss-precision and reliability, the Arctic SSNAV Auto was developed for pilots and everyday adventurers—with a white dial for increased visibility during daylight operations.

The watch represents the continued lineage of Marathon’s original Steel Navigator, developed in partnership with the Kelly Air Force Base in 1986.

The 41mm Arctic Steel Navigator Automatic (Arctic SSNAV Auto) is powered by a 26-jewel Sellita SW200-1, with Incabloc® Shock Absorber for added protection against vibration and harsh impact. This automatic version of the Steel Navigator is a return to the world’s original pilot’s watches – calling back to the pre-1980's era when most issued wristwatches were hand-wound or automatic.

The SSNAV Auto collection is built from 316L surgical-grade stainless steel with a screw-down crown and synthetic sapphire crystal, making it operational even when submerged to 10ATM (100m/300ft). The case design features enhanced lug tapering, providing a comfortable fit, and making an SSNAV Auto ideal for all-day wear. The increased height of the 12HR GMT bezel is specially designed to provide improved grip, allowing pilots to easily handle the bi-directional rotation while wearing flight gloves. The bezel also features inset-painted indices, enhancing the legibility of the markings.

Self-contained tritium gas tubes on the hour markers, and full hand set ensuring constant visibility in low-light environments. Tritium tubes are self-illuminating, containing an isotope of hydrogen that won't dull down over time like photoluminescent paint, meaning the watch will remain fully legible at all hours.

Protecting the dial of the Arctic SSNAV Auto is a highly durable sapphire crystal. This allows the watch to withstand extreme changes in air pressure – necessary for the watch’s use by military pilots at altitudes of over 35,000ft – while also providing scratch resistance and pristine clarity. The SSNAV Auto lineup is Swiss-made and Canadian-designed for premium quality and craftsmanship.
