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.
