Designed for operators who depend on absolute reliability, the TSAR 41mm is Marathon’s definitive mission-ready quartz diver — the watch issued to U.S. government search-and-rescue units around the world. Its iconic “US GOV” dial marking reinforces its lineage as a true service tool, built for those who work in unforgiving conditions where precision is not optional.

Engineered from 316L surgical-grade stainless steel and powered by a high-torque, 3-jewel Swiss-made quartz movement, the TSAR delivers unwavering accuracy in environments where mechanical watches can fail. With 300 meters of water resistance, a unidirectional dive bezel, and constant-glow tritium illumination, it maintains legibility through smoke, darkness, and deep-water pressure — conditions under which lives often depend on timing.

The 316L stainless steel bracelet transforms the TSAR into a rugged, daily-wearable instrument — offering increased durability, long-term comfort, and a premium military-tool aesthetic. The added weight and robustness of the bracelet make it ideal for both operational environments and everyday use, giving the watch a commanding presence on the wrist.

From rescue swimmers to military personnel, the TSAR remains a trusted tool — a watch chosen not for luxury, but for survival. This is Marathon’s purest expression of a government-spec search-and-rescue instrument: functional, rugged, and built with the singular purpose of performing when everything else stops.
