Marathon Search and Rescue (SAR) watches are developed to Canadian Government requirements for use in professional SAR operations. First introduced in the early 1990s, the SAR Series continues to be an essential kit element for elite members of both the Canadian and U.S. militaries. Submersible up to 30ATM and available in 46mm, 41mm, and 36mm iterations, these tool watches are fitted with knurled, screw-down crowns; iconic unidirectional, fully hashed bezels with 60-minute scales; highly legible dials outfitted with tritium tubes and MaraGlo luminescent material; and solid 316L stainless steel cases to provide ultimate endurance above or below sea-level.
