Paddling, skiing, trail running, open-water swims: the Marathon MSAR Auto WW194026SS-0530 is built for the kind of active days where a watch gets wet, cold and knocked around. This 36mm Swiss automatic diver combines an Arctic white dial with a black rubber strap for a light, sporty setup that stays comfortable from first light to last.

The rubber strap is the key to this listing's personality. It flexes with the wrist, does not mind sweat or salt water, and rinses clean under a tap, so the watch can go straight from the lake to the car without a second thought. Against the black rubber, the white dial pops, and it was chosen by Marathon specifically for legibility in bright and snowy conditions. Tritium gas tubes on the markers and hands keep the time visible on a dark morning start, with a MaraGlo pip on the bezel for timing intervals.

The case is Marathon's medium Search and Rescue design, built to Canadian Government requirements: brushed 316L stainless steel, sapphire crystal, a guarded screw-down crown, 300 meters of water resistance and a bezel big enough for gloved hands. A Sellita SW200-1 automatic movement with Incabloc shock protection handles the bumps. The Standard-Issue dial has no government markings, and the date sits at 4:30.
