MWC Stainless Steel GMT (Dual Time Zone) Military Watch with Sapphire Crystal and Ceramic Bezel on Silicon Band with 2 NATO Straps

Product Details

SKU Code: GMT/SS/SILB/QZ

This GMT dual time zone watch in a stainless steel finish is one of our most popular models, featuring a high-performance quartz Ronda 515.24 movement, an anti-reflective and impact-resistant sapphire crystal, and a scratch-resistant ceramic bezel. The robust 300m / 1000ft water-resistant steel casing makes it ideal for swimming, snorkeling, and water sports. However, since the bezel is designed for tracking time across two time zones, its suitability for diving applications is somewhat limited. That said, from a water-resistance perspective, the watch is fully capable of handling underwater environments.

The Concept of a GMT Watch

The idea behind GMT watches is both clever and straightforward. Unlike conventional watches, where the hour hand completes a 12-hour rotation, a GMT watch adds a second hour hand that completes a 24-hour rotation. This hand is paired with a 24-hour scale on the bezel, allowing the wearer to track a second time zone with ease.

GMT watches often resemble diver watches at first glance, but their functionality is distinct. The 24-hour hand moves once per day instead of twice, eliminating any confusion between AM and PM.

Designed for Pilots

We originally produced these watches for long-haul airline pilots and military transport pilots, including those flying aircraft like the Lockheed C-130 Hercules and Airbus A400M. The GMT functionality allows them to track both departure and destination time zones at a glance.

Understanding the Benefits of Sapphire Crystal

Many customers ask us about the advantages of sapphire crystal compared to standard mineral glass. The key benefits include:

• Superior Strength: Sapphire crystal is extremely strong and highly resistant to shattering and scratches.
• Ideal for Active Lifestyles: These qualities make it the preferred choice for military personnel, security forces, police officers, and outdoor enthusiasts—a group that makes up over 70% of our customer base.
• Exceptional Durability: From our experience, over 90% of watch crystal cracks occur in watches with mineral glass, even when hardened. Sapphire is significantly more durable in harsh conditions.
• Heat Treatment Process: After manufacturing, sapphire glass undergoes heat treatment to remove internal stresses, further enhancing its durability. Two anti-reflective coatings are also applied.
• Used in High-End Devices: Sapphire crystal is now even used in high-end smartphones, such as the latest iPhones.

Of course, sapphire crystal comes at a higher cost, which is why it is typically found only in premium timepieces. However, for those who demand long-term durability and clarity, the investment is well worth it.

    *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

    If you need to clarify any details regarding local taxes for your location, please contact us before placing an order. 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/. In the United States, orders under $800 do not incur taxes or fees. In Australia, orders up to AU$1000 are tax-free.

    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.
