Search and rescue divers work in cold, dark, moving water, and the Marathon OSAR-D was designed with that in mind. Reference WW194006SS-2004 is the 41mm Original Search and Rescue with Date in stainless steel, fitted with a black Type I dial and a stainless steel bracelet, and it is a genuine Swiss automatic dive watch rather than a desk diver in disguise.

Look at the dial and you see the priorities. The geometric indices are oversized and coated in MaraGlo, as are the hands, so the time stays readable in low light. A MaraGlo pip anchors the oversized unidirectional bezel, which ratchets through 120 clicks and can be gripped with gloves. The case is 316L stainless steel rated to 300 meters, with a screw-down crown shielded by guards and a sapphire crystal over the dial. Inside, the Sellita SW200-1 automatic is protected by Incabloc shock absorbers.

The OSAR-D's heritage gives all of that weight. Its predecessor, the SAR-D, was issued to Canadian SAR Techs in the early 2000s, and Marathon developed its SAR line to Canadian Government requirements. The steel bracelet adds a secure, durable finish for divers who prefer metal on the wrist.
