Product Details

SKU: NAV/AU/B/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.

    Failed delivery of an item ordered due to non-acceptance of the delivery

    Please note that if you order an item and the delivery company inform us that the item was refused it would be returned back to us, in many cases especially with FedEx, UPS etc they will also charge a return fee to send it back. Because in these circumstances we have done everything that is required to get the item to you we would refund less both the outbound and Inbound shipping charges once the item was received back at our packing and shipping centre. Unfortunately sometimes if you are having the order delivered to a business location the people receiving inbound parcels are prone to refuse an item without checking with the individual concerned we would strongly recommend being very cautious in this situation and notifying the people who handle the incoming parcels that you are expecting a delivery to avoid this problem occurring. Usually, we would be notified there is a delivery issue and would email you for your instructions, normally these sorts of problems can be avoided if you contact the carrier and tell them there is an error but it's very important to act quickly to avoid the return and associated costs.
