Sun glaring off fresh snow can wash out a dark dial in an instant. The Marathon MSAR Auto Arctic, reference WW194026SS-0503, answers with a crisp white face designed for legibility in bright, reflective conditions, set in a 36mm Swiss automatic dive watch on a stainless steel bracelet.

Marathon uses the Arctic name for its white-dial SAR models, and the idea is practical rather than decorative. Black hands and markers against white give instant contrast on a ski hill, on open water at midday, or on a glacier trail, places where a black dial can look like a mirror. When the light goes, tritium gas tubes on the markers and hands take over, glowing on their own without any charge. The dial is Standard-Issue, carrying the MARATHON name with no government markings, and a date sits at 4:30.

Under that bright face is the Medium Search and Rescue hardware Marathon developed to Canadian Government requirements: a 316L stainless steel case, sapphire crystal, screw-down crown with guards, an oversized 120-click bezel for gloved fingers, and 300 meters of water resistance. The 36mm size and 18mm lugs make it a natural fit for slimmer wrists and for wearing over a base layer.
