Marathon 41mm Anthracite GSAR Diver's Automatic Standard-Issue Type II WW194006BK-0109

The Marathon Anthracite GSAR was first issued in 2018 for stealth during tactical night missions. Hand-assembled, with a durable black anti-reflective Ion-Plating (IP) armor on its 316L Stainless Steel case and movement. Includes Anthracite Bracelet.

The Marathon 41mm Anthracite GSAR Diver’s Automatic Type II (ref. WW194006BK-0109) is the stealth version of one of the most respected military-issued dive watches in modern production. Originally developed for Search and Rescue divers and military personnel, the Anthracite GSAR takes the classic GSAR platform and gives it a black ion-plated finish designed for low-visibility tactical operations. Introduced around 2018 for night missions and special operations use, the watch combines Marathon’s uncompromising tool-watch design with a more aggressive, covert aesthetic that immediately separates it from traditional stainless steel divers.

Built from 316L stainless steel with a durable black IP coating, the 41mm case houses the Swiss Sellita SW200-1 automatic movement with Incabloc shock protection for added durability under extreme conditions. The watch features 300 meters of water resistance, a sapphire crystal, screw-down crown, and a unidirectional dive bezel, while Marathon’s signature tritium gas tube illumination provides constant visibility in complete darkness without requiring external charging.
