Marathon 46mm OSAR-D Diver's Auto Arctic Maraglo Type I WW194037SS-2501
The Marathon 46mm OSAR-D Diver’s Auto Arctic MaraGlo Type I (ref. WW194037SS-2501) is a full-scale professional tool watch built for extreme visibility and uncompromising durability. Developed from Marathon’s original SAR watches issued to Canadian Search and Rescue technicians in the early 2000s, the Arctic edition adds a high-contrast white dial specifically designed for bright, snowy, and low-contrast environments where standard black dials can become harder to read. The oversized 46mm brushed stainless steel case, deeply knurled bezel, and screw-down crown give the watch an unapologetically industrial feel—less luxury diver, more operational equipment.
Under the hood, the 46mm OSAR-D is powered by the Swiss Sellita SW600 b automatic movement with Incabloc shock protection, making it the first SAR-series Marathon to receive the upgraded caliber with an extended 62-hour power reserve. The watch features 300 meters of water resistance, sapphire crystal, magnified date window, and upgraded MaraGlo illumination for improved nighttime legibility. Unlike many oversized divers that exist purely for aesthetics, the OSAR-D Arctic feels purpose-driven in every detail—from the high-visibility dial to the thick, overbuilt case construction.
