White dials are not just a style choice at Marathon. The Arctic GSAR, reference WW194006SS-0510, exists because a white dial improves legibility in bright light and snow, exactly the conditions search and rescue crews often face. This 41mm Swiss automatic dive watch combines that Arctic dial with a brushed stainless steel case and a steel bracelet.

In practice, an Arctic dial gives the eye a bright field to read against, so the time registers quickly in sunshine, on snow or over glittering water. At night, the tritium gas tubes on every hour marker and hand take over, glowing on their own without any charging. Together they make the Arctic GSAR one of the most legible dive watches you can wear around the clock.

The rest is classic GSAR: a 300m case built to Canadian Government search and rescue requirements, a screw-down crown with guards, sapphire crystal, a 120-click unidirectional bezel, and the Swiss Sellita SW200-1 automatic with Incabloc shock protection. The stainless steel bracelet complements the bright dial with a crisp, all-steel look.
