Marathon
41mm 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. The Steel Navigator boasts enhanced functionality and unmatched accuracy that caters to pilots, parachutists, and adventurers. With the ETA F06.412 HeavyDrive-PreciDrive Quartz movement, it features accuracy of ± 10s/year and includes a date complication. 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). The refreshed case design features enhanced lug tapering for comfortable all-day wear. Self-contained tritium gas tubes ensure constant visibility in low-light environments.
