The Marathon Search & Rescue Diver’s Automatic is a dive watch built to ISO 6425 standards. Designed for use by Search and Rescue (SAR) divers and issued to the United States Marine Corps, the Diver’s Automatic is a watch built to withstand the most extreme conditions. The Diver’s Automatic is also known as the Government Search and Rescue (GSAR).

The Diver’s watch is water resistant down to 30 ATM - 300 meters (1000 feet) underwater. Built from 316L surgical grade stainless steel, the watch is a high quality, purpose built watch that will reliably accompany you wherever you take it. It uses a scratch resistant, sapphire glass crystal to ensure that the dial can be read even under direct sunlight, or deep underwater.

The Diver’s Automatic is made in La Chaux de Fonds Switzerland to guarantee the highest level of quality and accuracy in manufacturing. Inside the Diver’s Automatic is a Swiss Made, 26 Jewel Marathon M2 automatic movement made by Sellita, that guarantees you a reliable and accurate timekeeping experience.

The Diver’s Automatic 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.

This watch combines Military toughness with Swiss craftsmanship in a watch that will get the job done, and look good doing it.
