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

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.

    *Some countries are notoriously slow to process goods on arrival, including Israel, Hong Kong, Macau, Mexico, South Africa, and some South American countries. Significant delays can also occur in other countries in Africa. For time-sensitive deliveries, we recommend using UPS, DHL, or FedEx.

    All shipping estimates exclude Saturdays and Sundays.

    While we strive to deliver within the above timeframes, they are guides, and delivery cannot be guaranteed. We are not responsible for delays caused by couriers or any national postal service. If your goods are not delivered within the estimated time, please contact us at admin@mwc.watch, and we will do our best to resolve the issue promptly. We are not liable for any loss caused by late delivery.

    Our delivery charges cover the cost of shipping to you but do not include import charges and administration fees to clear the goods when entering your country if applicable.

    It is the purchaser's responsibility to understand that charges may be levied and to pay all subsequent import taxes and duties on goods shipped to their country. If items are returned to MWC due to rejected payment, subsequent charges incurred (such as import duty and processing costs) will be deducted from any refund issued. For more information, please contact accounts@mwc-distribution.com.

    We do not accept liability for goods lost after delivery to a PO Box. We reserve the right to cancel orders where the delivery address is a PO Box. Similarly, we do not accept liability for goods lost after confirmed delivery to APO or BFPO locations.

    Customer Notification: It is the customer's responsibility to notify us if goods are not received within 21 days of the estimated delivery date. If no notification is made within this period, the buyer is deemed to have received the goods.

    Safe Place Deliveries

    Some delivery companies allow for delivery without a signature, leaving the item in a "safe place" (e.g., shed, garage, porch). If you choose this option, it is at your own risk. We initially send items by a secure service requiring a signature or proof of delivery. Using a "safe place" increases the risk of theft. We advise ensuring deliveries require a signature to ensure safe receipt.

    Failed Deliveries

    If an item is refused and returned to us, we will refund the order less the outbound and inbound shipping charges once the item is received back at our packing and shipping center. For business locations, please notify the receiving personnel of the expected delivery to avoid refusals. Usually, we will be notified of delivery issues and will email you for instructions. It is important to act quickly to avoid return and associated costs.
