Summer, beach, boat, pool: this is the GSAR configuration for all of it. Marathon reference WW194006SS-0130 puts the 41mm stainless steel Large Diver's Automatic on a black 3-piece rubber strap, a lighter and more relaxed way to wear one of the most respected military-issue dive watches made today.

Rubber suits a diver's character. It doesn't mind salt, sweat or sunscreen, and it keeps the steel case feeling planted during active days. Marathon's 3-piece strap kit is made from FKM rubber in La Chaux-de-Fonds, Switzerland, where the watches are assembled, and it pairs with the black dial and brushed steel for a clean, purposeful look that recalls the GSAR's origins in search and rescue.

The specs back up the attitude. You get a Swiss Sellita SW200-1 automatic with Incabloc shock protection, 300 meters of water resistance, a sapphire crystal, a screw-down crown with guards and a unidirectional bezel with 120 clicks. Tritium gas tubes on every marker and hand stay visible day and night, through dawn swims and late bonfires alike.
