GSAR Swiss Made Military Issue Diver's Automatic Watch


Commonly known as the GSAR (Global Search and Rescue) Dive watch, this bulletproof diver is a no-holds-barred workhorse. Designed specifically for military aquatic use*, the GSAR features a sturdy 41mm stainless steel case with a depth rating of over 1000 feet and a thick sapphire crystal to prevent scratching and cracks.

The GSAR comes in several configurations to suit your exact needs. The base model comes on a 20mm black vulcanized rubber dive strap and can be purchased with either a “U.S. Government” or non-”U.S. Government” dial printing. 

The GSAR can also be equipped with a 20mm solid link stainless steel bracelet, adding heft and strength to the base model, or get the clasp engraved with the USMC Globe and Anchor. 

The self-winding Swiss movement drives the three hand display and date window with easy to use quickset functionality. A large knurled screw-down crown protects the movement from water and allows for setting while wearing gloves. 

Encapsulated Tritium (Isotope H3)  light sources mark the cardinal directions on the dial and illuminate all hands.** The unidirectional ratcheting bezel sports a MaraGlo triangle for viewing in low-light conditions.

Also available in Anthracite Black.
