The Marathon Diver’s Automatic Medium is a dive watch built to the same Mil-Spec standards but is a smaller, medium sized, version of Marathon’s line of diver’s watches, perfect for someone who wants a tough, reliable, and military issue dive watch, yet prefers a reduced size watch that is just as tough as its larger brothers.

The Marathon Search & Rescue Diver’s Automatic Medium is a dive watch designed for use by Search and Rescue (SAR) divers and issued to the United States Marine Corps, the Diver’s Automatic Medium is a watch built to withstand the most extreme conditions. The Diver’s Automatic Medium is also known as the Government Search and Rescue (GSAR). The watch is manufactured in accordance with US Government Specification. Issued to and worn by troops in Iraq and Afghanistan.

The Diver’s Automatic Medium 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 Medium uses self-contained Tritium gas tubes to ensure constant visibility in low light situations. A gas tube is placed on each hour marker and each hand. 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.
