Winter swims, spring paddles and summer dives all suit the Marathon 46mm OSAR-D Arctic Edition WW194037SS-2530-KIT. This large white-dial Swiss automatic dive watch comes on a 3-piece rubber strap kit, a light and water-loving setup that shows off the bright Arctic dial against black rubber.

The strap kit is Marathon's 3-piece FKM rubber, made in La Chaux-de-Fonds where the company assembles its watches. It stays comfortable wet or dry, resists salt water and chlorine, and keeps the 46mm case feeling less heavy than it would on steel. Fitted to the 22mm lugs, it gives the OSAR-D a sporty, purposeful look that is ideal around boats, docks and frozen lakes alike. The white dial, chosen by Marathon for legibility in snow and bright light, contrasts sharply with the black strap and makes the time instantly readable.

Inside, the Sellita SW600 b automatic movement delivers 62 hours of reserve, 24 jewels and Incabloc shock protection, making the 46mm OSAR-D the first SAR model with this caliber. MaraGlo lume brightens the large geometric indices, hands and bezel pip, and a 1.5x cyclops magnifies the date at 3. The brushed 316L case, 17mm thick and 55mm lug to lug, seals with a guarded screw-down crown to 300 meters under sapphire crystal.
