41mm Titanium Large Diver's Automatic (GSAR)
Price includes taxes and fees.
Introducing the 41mm Titanium Government Search and Rescue dive watch. New material. Same unwavering purpose.
For the first time in Marathon history, the most trusted SAR watch has been re-engineered in TAA-compliant grade 5 titanium. Building on the proven foundation of the current 41mm GSAR, this new evolution introduces the first lightweight titanium case to the Marathon lineup. The end result delivers roughly twice the tensile strength as stainless steel and enhanced corrosion resistance, without compromising the rugged dependability that defines the SAR series.
A Sellita SW200-2 Top Grade movement with Incabloc® Shock Absorber powers the Titanium GSAR. This new movement provides an increased power reserve of 65 hours, as well as an enhanced accuracy range.
Designed for wearers that count on their tool watch in any situation, the Titanium GSAR reduces weight on the wrist by 30%, while enhancing the functionality of its stainless steel counterpart.
From ocean depths to the demands of everyday duty, it's a purpose-built instrument engineered to go farther, weigh less, and stand the test of time.
Supplied strap system: Black Swiss-made FKM 3-piece rubber strap kit, equipped with titanium hardware.

SAME OBJECTIVE. UPGRADED MATERIAL.
When the SR-71 launched in the 60s, one of the most advanced military aircraft ever conceived took flight with an extraordinary material. Titanium gave the SR-71 strength and resilience, reducing weight while maintaining the structural integrity required for extreme environments. It was a material chosen for capability, not convention.
In 2026, a new mission starts and that same philosophy will be applied to the GSAR— Marathon’s most sought-after model—re-engineering it in TAA-compliant grade 5 titanium for the first time ever.
PROVEN PLATFORM. ADVANCED ABILITY.
Commonly known as the Government Search and Rescue, the 41mm GSAR was Marathon’s first Type II automatic SAR watch. Since its introduction, it’s become one of the most trusted SAR platforms. And now, the GSAR becomes the first standard production model to be offered in a lightweight, titanium case.
The titanium version will be powered by the Sellita SW200-2 Top Grade movement equipped with Incabloc® Shock Absorber, notable for its 65-hour power reserve and elevated timekeeping precision.
The dial has been designed with several subtle differences compared to the steel GSAR version, including a black date wheel, updated typeface, and the “Ti” letters in “AUTOMATiC” set in red to represent the periodic table’s symbol for titanium.
