MARATHON 41MM STEEL NAVIGATOR W/ DATE (SSNAV-D) ON BALLISTIC NYLON
With the ETA F06.412 Heavy Drive-PreciDrive Quartz movement, the 41mm Steel Navigator with Date (SSNAV-D) stands out with unmatched precision, featuring an accuracy of 10s/year. This model also exhibits a date complication - a first for any Steel Navigator since the design's initial launch in the 1980s. The SSNAV-D is 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, providing a comfortable fit making the SSNAV-D ideal for all-day wear. The increased height of the 12HR GMT bezel is specially designed to provide improved grip, allowing pilots to handle the bi-directional rotation while wearing flight gloves easily. The bezel also features inset-painted indices, enhancing the legibility of the markings.
Self-contained tritium gas tubes on the hour markers, and minute/hour hands ensuring constant visibility in low-light environments. Tritium tubes are self-illuminating, containing an isotope of hydrogen that won't dull down over time like photoluminescent paint, meaning the watch will remain fully legible at all hours.
