White dials exist on dive watches for a reason, and the Marathon TSAR Arctic WW194007SS-0509 shows it best on a bright winter morning. This 41mm Tritium Search and Rescue quartz diver pairs a crisp white Arctic dial with a stainless steel bracelet for maximum legibility when the light is harsh and the ground is covered in snow.

Marathon's Arctic dials were conceived for conditions where a black dial can turn into a dark mirror: glare off snow, ice, open water or a sunlit cockpit. Against white, the black hands and markers pop instantly. After sunset, the advantage carries over, because the indices and main hands still carry tritium gas tubes that glow continuously with no charging required, while MaraGlo handles the bezel pip and seconds hand. It is a watch that reads clearly at noon on a glacier and at midnight in a tent.

Skiers, winter hikers, ice fishermen and anyone who spends serious time outside in the cold will appreciate the rest of the package too. The Swiss ETA F06.115 HeavyDrive quartz is indifferent to whether you wore it yesterday, the oversized bezel is designed to be turned with gloves on, and the screw-down crown keeps meltwater out.
