The Marathon Search & Rescue Diver’s Quartz is a diver’s watch with a high torque, accurate Swiss quartz movement. Designed for use by Search and Rescue (SAR) divers and manufactured under ISO 6425 standards, the Diver’s Quartz is a watch built to withstand the most extreme conditions. The Diver’s Quartz is also known as the Tritium Search and Rescue (TSAR).
The Marathon TSAR is water-resistant down to 30 ATM - 300 meters (1000 feet) underwater. Made from 316L surgical grade stainless steel, the TSAR is a purpose built watch that will not let you down. The glass of the TSAR is in fact not glass, but a synthetic sapphire that resists scratches.
The TSAR is handmade in La Chaux-de-Fonds Switzerland to guarantee the highest level of quality and accuracy in manufacturing. Inside the TSAR is a Swiss made, 3 jewel ETA F06 high torque quartz movement.
The TSAR uses self-contained Tritium gas tubes to ensure constant visibility in low light situations. A gas tube is placed on each hour marker, each hand, and uses MaraGlo for the 12-hour bezel marker. Tritium tubes are self illuminating gas tubes which contain an isotope of hydrogen, meaning they will not dull down in brightness like normal photo-luminescent paint, which requires an external light source to create a glow.
The TSAR combines Military toughness with Swiss craftsmanship in a watch that will get the job done, and look good doing it.
