SSNAV-D Auto Pilot's Automatic Steel Navigator Date 41MM Watch by Marathon (WW194030SS)

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.
