Glare is the enemy of a quick time check. On a sunlit ski slope, a frozen lake or a bright beach, a dark dial can turn into a mirror. The Marathon 36mm OSAR-D Arctic Edition WW194026SS-2502 solves that with a white dial built for bright-light and snow legibility, on a Swiss automatic dive watch with a stainless steel bracelet.

Marathon developed its Arctic dials precisely for those conditions. Dark hands and bold outlines stand out sharply against white, so the time registers in a fraction of a second even through sunglasses or goggles. The OSAR-D adds large geometric indices that are easy to tell apart by shape, plus a cyclops magnifier over the date at 3 o'clock. MaraGlo lume on the indices, hands and bezel pip absorbs that abundant daylight and returns it as glow after sundown.

Winter-ready construction backs up the dial. The 36mm brushed steel case is sealed with a guarded screw-down crown to 300 meters, the crystal is sapphire, and the oversized bezel is sized to turn with gloves on, a direct inheritance from Marathon's search-and-rescue designs built to Canadian Government requirements. At 13mm thick, the watch slides under a jacket cuff without catching, and the Sellita SW200-1 automatic movement inside carries Incabloc shock protection.
