The Marathon 41mm Titanium GSAR represents a new evolution of one of the brand's most recognized search and rescue watches. For the first time in Marathon's history, this model features a TAA-compliant Grade 5 titanium case, preserving the platform that has defined the GSAR while adapting it to a lighter and more corrosion-resistant material. The result is a tool watch that retains its original purpose while reducing weight and enhancing corrosion resistance.

A New Chapter for the GSAR

Known as the Government Search and Rescue, the 41mm GSAR was Marathon's first Type II automatic SAR watch. Since its introduction, it has become one of the brand's most trusted platforms. Now, the model takes an important step forward by becoming Marathon's first standard production watch available with a lightweight titanium case.

The choice of material reflects a philosophy in which every component must serve a specific purpose. Grade 5 titanium offers approximately twice the tensile strength of stainless steel, along with enhanced corrosion resistance. These properties allow the GSAR to retain its characteristic ruggedness without adding unnecessary weight to the wrist.

Titanium: Strength Without the Extra Weight

The introduction of titanium also connects with a historical milestone in engineering. When the SR-71 took flight in the 1960s, this advanced military aircraft used the material for its ability to combine structural strength with reduced weight, even in extreme conditions. It was a choice driven by performance requirements rather than aesthetics.

In 2026, Marathon applies a similar philosophy to the GSAR, introducing TAA-compliant Grade 5 titanium to the model for the first time. The new case features a brushed finish and reduces the weight on the wrist by 30% compared with its stainless steel counterpart. In this way, the watch maintains its functional focus while offering a lighter wearing experience.

A Movement with Greater Autonomy

The Marathon 41mm Titanium GSAR is powered by the Sellita SW200-2 Top Grade automatic movement, equipped with an Incabloc® shock absorber. One of the most notable improvements is its 65-hour power reserve, extending the time the watch can run without requiring additional winding. The movement also offers an enhanced accuracy range, according to the specifications provided by the brand.

This mechanical update reinforces the model's evolution without changing its identity as a professional instrument. The combination of a top-grade movement, shock protection, and a titanium case emphasizes both performance and the durability required to accompany its wearer in a variety of situations.

Details That Distinguish the Titanium Version

Although it retains the foundation of the stainless steel GSAR, the new version introduces several subtle changes to the dial. These include a black date wheel and an updated typeface. Additionally, the letters "Ti" in the word "AUTOMATiC" appear in red, referencing titanium's chemical symbol on the periodic table.

The watch retains essential elements of its functional identity, including tritium gas tubes and MaraGlo luminous material. A sapphire crystal protects the dial, while the screw-down crown and unidirectional bezel with a 60-minute scale complete a configuration designed for use as a dive watch. Its water resistance is rated at 30 ATM.

The package is completed by a black, Swiss-made FKM rubber strap system consisting of three pieces and equipped with titanium hardware. This configuration maintains material consistency between the case and the components that accompany the watch.

The Evolution of an Instrument with a Clear Purpose

The Marathon 41mm Titanium GSAR does not seek to reinvent an established platform. Instead, it improves upon it through material selection and mechanical upgrades. Its Grade 5 titanium case, 30% weight reduction, and Sellita SW200-2 Top Grade movement with a 65-hour power reserve represent the main differences compared with the stainless steel version.

With this new interpretation, Marathon preserves the essence of the Government Search and Rescue while adapting its construction to the needs of those who require a durable, functional watch capable of accompanying them in demanding environments and everyday life. The same purpose, new materials, and an evolution focused on performance.
