Marathon 41mm Pilot's SSNAV-D Auto Tritium Type II WW194030AN-US250

The Marathon 41mm Pilot's SSNAV-D Auto Tritium Type II WW194030AN-US250 is a purpose-built military pilot's watch created to commemorate the 250th anniversary of the United States. Produced as a limited edition of just 250 pieces worldwide, this special reference builds upon Marathon's legendary Steel Navigator platform—originally developed in partnership with Kelly Air Force Base in 1986—with exclusive commemorative details throughout. The anthracite ion-plated 316L stainless steel case is paired with a matte black dial featuring a subtle "1776" appliqué encircled by stars, a red tritium tube at 12 o'clock inspired by "the rockets' red glare," and a matching anthracite 12-hour bidirectional bezel. Measuring 41mm with a screw-down crown, sapphire crystal, and 100 meters of water resistance, the WW194030AN-US250 combines genuine military heritage with modern Swiss engineering in one of Marathon's most exclusive releases.

Powering the watch is the Swiss-made Sellita SW200-1 automatic movement with Incabloc shock protection, delivering dependable precision, hacking seconds, hand-winding capability, and a 41-hour power reserve. Self-illuminating tritium gas tubes provide constant readability in complete darkness without requiring exposure to light, while the exhibition caseback—another first for the Navigator collection—reveals the anthracite-coated movement and features patriotic engravings celebrating America's 250th anniversary. Finished with a premium bison leather strap and produced in an exceptionally limited run, the WW194030AN-US250 stands as both a professional-grade pilot's instrument and a highly collectible commemorative timepiece, blending Marathon's military legacy with meaningful historical significance.

Popular models like the Marathon GSAR (Government Search and Rescue) and TSAR (Tritium Search and Rescue) are built to withstand extreme environments, making them a go-to choice for divers, pilots, and professionals.

Today, Marathon continues to produce military-issued watches, combining Swiss craftsmanship, rugged durability, and tactical design. If you're searching for a reliable tool watch with real military heritage, Marathon stands in a class of its own.
