Search and rescue is a race against the clock, and the Marathon CSAR WW194014SS-0109 was built with that reality in mind. This 46mm Swiss automatic chronograph, with a matte black Standard-Issue dial and stainless steel bracelet, is Marathon's answer to the question of what a rescue professional needs on the wrist when every minute counts.

Marathon developed its SAR line to Canadian Government requirements, and the CSAR adds a chronograph to that formula so crews can track mission time, intervals and elapsed hours without a separate device. A unidirectional 60-minute bezel provides a second way to track time, and it is oversized and grippy enough to turn with gloves. Tritium gas tubes on the hour markers and hands glow constantly, independent of any light source, while MaraGlo on the subdials, pip and seconds hand helps read the chronograph in the dark.

The rest of the spec is about survival. A 316L steel case rated to 30 ATM, a screw-down crown flanked by guards, a sapphire crystal and an ETA Valjoux 7750 automatic movement with Incabloc shock protection give it the toughness that rescue work demands. The Standard-Issue dial keeps it free of any government text, so it carries that heritage without any unit or agency identification.
