Description
Marathon 41mm Titanium Large Diver's Automatic (GSAR™) – A legendary reference in military diving watches, the GSAR™ (Government Search and Rescue) is offered here in an exceptional version forged in Grade 5 titaniumDesigned in La Chaux-de-Fonds, Switzerland, according to the strict requirements of MIL-PRF-46374G and ISO 6425 standards, this intervention watch combines the lightness and exceptional thermal resistance of titanium with a proven water resistance of 300 meters (30 ATM / 1000 feet).
Designed for extreme tactical operations and deep-sea diving, the GSAR™ Titanium offers superior wearing comfort thanks to a significant weight reduction compared to steel, while maintaining absolute mechanical robustness.
Permanent Illumination: H3 Tritium Tubes (Day/Night Vision)
Use the ↔ slider to compare the daytime vision of the dial and the constant luminescence of the Tritium H3 microtubes.
La Marathon GSAR™ Titanium 41mm is distinguished by its autonomous lighting system composed of Tritium (H3) gas micro-tubes Applied to each hour marker as well as the hour, minute, and second hands. Unlike conventional phosphorescent paints, gaseous tritium emits a constant light without requiring any prior exposure to an external light source, guaranteeing perfect legibility in total darkness for over 25 years.
Powered by a high-precision Swiss automatic movement (Sellita SW200-1 with Incabloc® shock absorber), the watch is housed in a monobloc case made of matte, non-magnetic titanium that is highly resistant to salt corrosion. The unidirectional bezel with deep notches (120 clicks) allows for precise measurement of dive times, even when wearing tactical or diving gloves.
The black tactical dial features a 24-hour scale (military time) and a discreetly positioned date window between 4 and 5 o'clock. The scratch-resistant synthetic sapphire crystal provides optimal protection for the display. This model comes with a 20mm ergonomic black vulcanized rubber strap.
