MWC 300m Water Resistant Stainless Steel Tritium GTLS Navigator Watch (Automatic)

SKU: NAV/AU/ST/SL

These robust 300m water-resistant watches are specifically designed for marine, surface, and airborne navigation applications, meeting U.S. MIL-PRF-46374G specifications. Each watch features a 12-hour ceramic bezel for easy and straightforward tracking of a second time zone. The bezel has high-visibility numerals, and the dial is clear and easy to read even in adverse light conditions. The watch uses Tritium GTLS (Gaseous Tritium Light Sources), which are significantly brighter than conventional luminous watches.

Key Features:

• Movement: High-quality NH35A Automatic movement designed to withstand high G-forces.
• Water Resistance: 30 ATM (1000 ft/300m), with the same water resistance rating as our diver models, featuring a screw-down crown and caseback.
• Dual Time Zones: The rotating outer ceramic bezel allows the watch to display the time in two different time zones simultaneously.
• Altitude Accuracy: Maintains high accuracy at altitudes up to 12,000m / 40,000ft without compensatory pressurization.
• Illumination: Uses Tritium GTLS for superior nighttime visibility.

Tritium and Safety:

The dial features a radioactive tritium symbol. Tritium, a radioactive isotope of hydrogen, emits beta particles that do not penetrate skin, plastic, or glass. The vials contain less than the personal limit of 25 millicuries, as per U.S. Nuclear Regulatory Commission regulations (10 CFR 30.15).

Benefits of Sapphire Crystal:

Synthetic sapphire is the best material for watch crystals due to its exceptional strength and resistance to shattering and scratching. This makes it ideal for military, security personnel, police officers, and active outdoor enthusiasts, who account for over 70% of our customers. Over 90% of cracked crystals in client watches are mineral glass, even when hardened. Sapphire crystals, heat-treated to remove internal stresses and coated with two layers of anti-reflective material, offer superior durability. This is why sapphire crystal is standard in high-end watches and even in the latest iPhone models, despite the higher cost.
