Swap the bracelet for rubber and the Marathon OSAR-D becomes a dedicated water companion. Reference WW194006SS-2030 is the 41mm Original Search and Rescue with Date on a black rubber strap, a Swiss automatic dive watch with a black Type I dial that is ready for snorkeling, paddleboarding or a weekend on the boat.

Rubber changes how this watch lives on the wrist. It is lighter, it doesn't mind salt or chlorine, and it dries quickly after a swim. The watch is equally prepared: its 41mm, 13.5mm-thick case is rated to 300 meters, its sapphire crystal resists scratches, and the 120-click unidirectional bezel lets you track time in the water. MaraGlo lume on the oversized geometric indices, hands and bezel pip charges in the sun so it is bright when you need it.

The OSAR-D reintroduced in 2024 the design Marathon once supplied to Canadian Search and Rescue Technicians, including the cyclops-magnified date at 3 o'clock. Paired with the Swiss Sellita SW200-1 automatic and Incabloc shock protection, it gives you heritage and capability in one easygoing package.
