A robust tool watch that represents a fully re-engineered upgrade to Marathon's original Steel Navigator, developed in partnership with the Kelly Air Force Base in 1986. Featuring a white dial for increased visibility during daylight operations, the Arctic SSNAV-D boasts unmatched precision with ETA F06.412 HeavyDrive-PreciDrive Quartz movement providing accuracy of ± 10s/year. Built from 316L surgical-grade stainless steel with a screw-down crown and synthetic sapphire crystal, making it operational even when submerged to 10ATM (100m/300ft). Features self-contained tritium gas tubes on hour markers and hands for constant visibility in low-light environments.
