Marathon 41mm Diver's Automatic OSAR-D Arctic Type I WW194006SS-2501

The 41mm OSAR-D Arctic Edition builds on the strengths of the SAR-D, originally issued to Canadian SAR (Search and Rescue) Techs in the early 2000s. Today’s OSAR-D is re-engineered with upgraded MaraGlo illumination, larger indices, improved cyclops and a Sellita SW200-1 automatic movement with Incabloc® Shock Absorber. Continuing the tradition of offering a white dial option for models in the SAR lineup, the Arctic OSAR-D provides better legibility in bright and snow-blind scenarios.


The Marathon OSAR-D Arctic Type I 41mm (WW194006SS-2501) is a specialized evolution of the brand’s military-issued dive watches, built with a sharper focus on operational functionality and clarity. Housed in a robust stainless steel case, this model features a striking white “Arctic” dial that maximizes contrast against its bold black hands and markers, all powered by tritium gas tubes for constant, maintenance-free illumination. The dial layout is purpose-driven and sterile, emphasizing quick readability, while the unidirectional bezel and screw-down crown reinforce its professional-grade dive capabilities. At its core, a reliable automatic movement ensures consistent performance in demanding conditions.

What sets the OSAR-D Arctic apart is its stripped-down, mission-first design—it’s engineered for real-world use, not aesthetic flex. With 300 meters of water resistance, a sapphire crystal, and the durable Type I bracelet, it’s built to handle extreme environments without compromise. The high-contrast Arctic dial gives it a unique visual edge while enhancing legibility in snow, water, and low-light scenarios alike. For collectors who appreciate true field gear with military pedigree, the OSAR-D Arctic stands as a no-nonsense, highly capable tool watch that delivers exactly what it promises.
