Marathon
41mm Arctic Steel Navigator w/Date (SSNAV-D) on Black 3-Piece Rubber Strap Kit

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 accuracy that caters to pilots, parachutists, and adventurers. 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 the hour markers and hands for constant visibility in low-light environments.
