Marathon 41mm Diver's Automatic OSAR-D Standard-Issue Type I WW194006SS-2030

Originally issued to Canadian SAR (Search and Rescue) Techs in the early 2000's, the 41mm SAR-D marked the beginning of the Marathon SAR line. The watch famously featured a mil-spec Type I dial with cyclops date, designed with fully-lumed geometric hour markers providing quick legibility and maximum visibility under water or in dark environments.


The Marathon 41mm Diver’s Automatic OSAR-D Type I (ref. WW194006SS-2030) is a pure no-nonsense military tool watch designed for actual Search and Rescue operations, not just vintage-inspired aesthetics. Originally issued to Canadian SAR technicians in the early 2000s, the OSAR-D helped define Marathon’s reputation for building brutally functional watches for military and government use. Its 41mm 316L stainless steel case, oversized bezel, screw-down crown, and highly legible Type I dial are all engineered around visibility, durability, and underwater performance rather than luxury finishing or trend-driven design.

Powered by the Swiss Sellita SW200-1 automatic movement with Incabloc shock protection, the OSAR-D combines dependable mechanics with true field-ready toughness. The watch features MaraGlo illumination, sapphire crystal, a magnified cyclops date, and 300 meters of water resistance—making it capable far beyond everyday use. Unlike many modern dive watches that lean heavily into heritage styling, the OSAR-D feels purpose-built and industrial, with a utilitarian aesthetic that appeals to collectors who appreciate genuine military provenance and uncompromising functionality.

Marathon Watches is a Canadian watch company with roots dating back to 1939, though the Wein family’s involvement in watchmaking stretches back to the early 1900s. Founded in Montreal by Morris Wein, Marathon built its reputation producing timing instruments and military watches for Allied forces during World War II. Today, the brand remains one of the few companies still manufacturing watches to official military specifications for government and military use.

What makes Marathon unique is its focus on true utility. Marathon watches are designed in Canada and manufactured in Switzerland, combining Swiss production quality with genuine military heritage. Models like the GSAR and TSAR are known for their rugged construction, tritium tube illumination, and highly legible dials built for search and rescue operations, diving, and field use.

Unlike many modern tool watch brands, Marathon continues to prioritize function over luxury marketing. That authenticity has earned the brand a loyal following among collectors, military personnel, and enthusiasts who appreciate purpose built watches with real operational history.
