It offers outstanding functionality and unmatched precision, specifically designed for pilots, parachutists, and adventurers.

All-Terrain Capable

• Powered by the ETA F06.412 HeavyDrive-PreciDrive Quartz movement, providing ultra-high accuracy of ± 10s/year. This is the first model in the Steel Navigator series to feature a date display.
• Constructed with a 316L surgical-grade stainless steel case, a screw-down crown, and a sapphire crystal, offering water resistance up to 10 ATM (100 meters/300 feet).

Refined Design Enhancements

• The upgraded case design improves the taper of the lugs, making the watch more comfortable and secure for all-day wear.
• The 12-hour GMT bezel has been raised, significantly enhancing grip, allowing for easy operation even with flight gloves.
• The bezel markings feature an embedded lacquer design to enhance readability and clarity.

High-Performance Luminous Features

• Self-illuminating tritium gas tubes are applied to the hour markers and hour/minute hands, ensuring superior legibility in low-light environments.
• The tritium gas tubes do not fade over time, ensuring the watch remains clearly visible at all times.

Pressure-Resistant, Scratch-Proof Sapphire Crystal

• The sapphire crystal can withstand extreme pressure changes, which is particularly important for military pilots operating at altitudes above 35,000 feet.
• It offers excellent scratch resistance, maintaining the clarity of the dial, making it the best material for watch crystals today.

Professionally Designed Nylon DEFSTAN Strap

• This watch comes with a Nylon DEFSTAN strap, meeting the standards of the British Ministry of Defence, offering high strength, durability, and exceptional comfort.
