Snow, ice and low winter sun are hard on the eyes, and that is exactly the environment the Arctic dial was made for. Marathon reference WW194006SS-2502 is the 41mm Arctic OSAR-D: a Swiss automatic dive watch with a white Type I dial, a brushed steel case and a stainless steel bracelet, ready for cold-weather adventures.

A white dial keeps the time easy to read when everything around you is glaring, and the OSAR-D's oversized geometric indices make the layout readable even at a quick glance from a ski lift or a snowshoe trail. Once the short winter day fades, MaraGlo on the indices, hands and bezel pip glows for hours after charging in daylight. The large unidirectional bezel, with 120 clicks, is easy to turn with gloves.

Built to search and rescue standards, the Arctic OSAR-D handles moisture and impact with ease. The 316L case is rated to 300 meters, sealed with a screw-down crown inside protective guards, and the sapphire crystal resists scratches. A Swiss Sellita SW200-1 automatic keeps time, and the cyclops-magnified date at 3 o'clock keeps you on schedule.
