Collectors who already own a black-dial Marathon will find the ideal counterpart in the Arctic OSAR-D. Reference WW194006SS-2504 is the 41mm Original Search and Rescue with Date in its Arctic edition, introduced in 2025 with a white Type I dial, a brushed stainless steel case and a stainless steel bracelet.

The OSAR-D's collectibility comes from its lineage. Its ancestor, the SAR-D, was issued to Canadian Search and Rescue Technicians in the early 2000s, and its Type I dial with geometric indices and a cyclops date became a signature of that era. Marathon re-engineered the design and relaunched it in 2024, then followed up with this Arctic version, continuing the brand's tradition of offering white dials for SAR models.

The details reward a closer look. The 1.5x cyclops magnifies the date at 3 o'clock, MaraGlo lume coats the indices, hands and bezel pip, and the 41mm case is 13.5mm thick and 48mm lug to lug. It is rated to 300 meters, protected by a screw-down crown with guards and sapphire, and powered by the Swiss Sellita SW200-1 automatic with Incabloc shock absorbers.
