MARATHON AIR PILOT'S SSNAV-D-AUTO STEEL NAVIGATOR WITH DATE AUTOMATIC 41MM RUBBER

The 41mm SSNAV-D AUTO known as the Steel Navigator w/ Date Automatic (SSNAV-D AUTO)

The 41mm Steel Navigator w/ Date Automatic (SSNAV-D AUTO) is the first ever Steel Navigator to feature a self-winding automatic movement. Packed with Swiss-precision and reliability, the SSNAV-D Auto is developed for pilots and everyday adventurers. The watch represents the continued lineage of Marathon’s original Steel Navigator, developed in partnership with the Kelly Air Force Base in 1986.

PURPOSE-BUILT FOR ANY TERRAIN

The 41mm Steel Navigator w/ Date Automatic (SSNAV-D 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. This model also exhibits a date complication at the 4:30 position.

The SSNAV-D Auto 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 the SSNAV-D 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 SSNAV-D 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-D Auto is Swiss-made and Canadian-designed for premium quality and craftsmanship.

Included with the watch is the 3-Piece Rubber Strap Kit, also manufactured in La Chaux-de-Fonds, Switzerland. The strap kit is crafted from FKM Rubber and is designed to meet the requirements of high-performance military applications. The 3-Piece Kit comes with one (6 o'clock) tail piece with 8 adjustment holes, and two (12 o'clock) buckle pieces of different sizing that allow the wearer to tailor the length to fit their wrist size.
