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 of conditions. The Diver’s Automatic is also known as the
Government Search and Rescue (GSAR).
The GSAR 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 on any adventure you
may embark on. It uses a scratch resistant, sapphire glass crystal to ensure that the
dial can be read even under direct sunlight, or deep underwater.
Our dials and hands use self-contained tritium gas tubes to ensure
constant visibility in low light situations, a gas tube is placed on each
hour marker and hands 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.
Marathon watches are 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 Sellita SW200 automatic
movement, that guarantees you a reliable and accurate timekeeping experience.
This watch combines military toughness with Swiss craftsmanship in a
watch that will get the job done, and look good doing it.
