41MM NAV

With the ETA F06.105 HeavyDrive Quartz movement, the 41mm Navigator (NAV) features an accuracy rating of -0.2 to +0.5 seconds per day. The NAV is constructed with bio-sourced plastic and ceramic powder with a push down crown and synthetic sapphire crystal, making it operational even when submerged to 6ATM (60m/195ft).

The refreshed case design features enhanced lug tapering, providing a comfortable fit making the NAV ideal for all-day wear. The increased height of the 12HR aluminum GMT bezel is specially designed to provide improved grip, allowing pilots to easily handle the bi-directional rotation while wearing flight gloves. The bezel also features inset-painted indices, enhancing the legibility of the markings.
 
Self-contained tritium gas tubes on the hour markers, the minute/hour hands, and the bezel pip ensure 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.

Protecting the dial of the NAV is a highly durable sapphire crystal. This allows the watch to withstand extreme changes in air pressure – necessary for the watch’s use by military pilots at altitudes of over 35,000ft – while also providing scratch resistance and pristine clarity. 

The 41mm NAV is Swiss-made and Canadian-designed for premium quality and craftsmanship.
