MWC NATO Pattern Stainless Steel Military Pilots Chronograph with Sapphire Crystal and Swiss Ronda Movement

Product Details

SKU Code: TN4/WD/CDB

The MWC NATO chronograph in a stainless steel case is designed to meet the needs of military aircrews, airline pilots, and GA pilots. While based on the same specifications used by several other leading military manufacturers of NATO chronographs, this watch includes several improvements for enhanced operation and visibility. The case size is 45.5mm, and the chronograph uses a high-performance Swiss Ronda 5040.D movement.

Ronda 5040.D Sub-Dial Functions:

Left Sub-Dial (9 o'clock):

• 60-minute counter (chronograph)
• Tracks elapsed minutes when the chronograph is running.
• Goes up to 60 minutes.

Bottom Sub-Dial (6 o'clock):

• 6 o'clock (Bottom sub-dial): Chrono hours (up to 12)

Right Sub-Dial (3 o'clock):

• Small seconds (continuous running seconds for the main time)
• This one’s always running — has nothing to do with the chronograph function.

🕹️ Chronograph Controls:

• • Top pusher (Start/Stop): Starts and stops the chrono.
  • Bottom pusher (Reset): Resets the chronograph hands to zero (after it’s stopped).

📝 Pro Tip:

If the chrono hands are out of alignment (say, the 1/10th sec hand isn't zeroing properly), you can recalibrate them via the crown pulled out to the second position — each pusher moves a different hand. This means that whereas with many chronographs they need to be booked into a watchmaker to make minor adjustments. This does not apply in the case of this particular model because it is a simple job to find the calibration yourself if it's ever required.

Operation:

When you push the top button, you get a crisp response, and the timing hand starts ticking. The stop button at 5 o’clock provides the same crisp feel when stopping the chronograph, and pressing it again snaps the hand straight back to 12.  Practical Benefits:

These models are ideal for those who own multiple watches because they don’t need to be wound before wearing them. All they require is a battery swap every few years and a check of the water resistance. One unique aspect is the absence of a tick, making it indistinguishable from a mechanical watch based on behavior alone.

Benefits of Sapphire Crystal:

Synthetic sapphire is extremely strong, shatter-resistant, and scratch-resistant, making it ideal for military and security personnel, police officers, and active outdoor enthusiasts. These groups account for over 70% of our customer base. Our observations show that over 90% of incidents involving cracked watch crystals occur with mineral glass. Even hardened mineral crystals do not match the durability of sapphire. Sapphire crystals are strengthened through heat treatment to remove internal stresses and coated with two layers of anti-reflective coating. Although sapphire crystals are more expensive, they offer superior longevity, resilience, and performance, justifying their use in higher-end watches.

The MWC NATO chronograph in stainless steel combines modern technology's reliability and precision with the rugged design and functionality needed for professional use. Its robust features and user-friendly design make it an exceptional choice for both professionals and enthusiasts.

    *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 clarification, goods shipped to the EU can be dispatched from our EU location if ordered at https://mwc.eu/, and we also have a dedicated UK shipping center at https://mwcwatches.co.uk/.

    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.
