A white dial dive watch on a steel bracelet is one of the most versatile things you can wear, and the Marathon Arctic OSAR-D gives that formula a military backstory. Reference WW194006SS-2503 is the 41mm Arctic Original Search and Rescue with Date, a Swiss automatic with a white Type I dial, a brushed 316L case and a stainless steel bracelet.

Visually, the Arctic OSAR-D is crisp and graphic. The large geometric indices give it a bold, purposeful look, the cyclops at 3 o'clock magnifies the date by 1.5x, and the bright dial lifts it beyond the usual all-black tool watch. It pairs as easily with a crisp white shirt as with board shorts, and its 13.5mm-thick case slips under most sleeves.

Underneath the style is real capability. The OSAR-D is the modern relaunch of the SAR-D issued to Canadian SAR Techs in the early 2000s, so it is rated to 300 meters and fitted with a screw-down crown with guards, a sapphire crystal and a unidirectional 120-click bezel. MaraGlo lume on the indices, hands and bezel pip handles low light, and the Swiss Sellita SW200-1 automatic winds itself as you go about your day.
