MWC 21 Jewel 1980s Pattern 300m Automatic Military Divers Watch with Sapphire Crystal and a Black and a Grey NATO Strap

Product Details

Product Code: SUB/MILSSAU/MY

These diver's watches are a remake of a 1980s model we produced until around 35 years ago. The watch features a robust stainless steel case and is equipped with a high-performance automatic 21,600 bph 21-jewel self-winding movement. We have made several upgrades to the original design, including a shatter and scratch-resistant sapphire crystal and an increased water resistance rating. The dial and caseback are both unbranded (referred to in the military as sterile), giving the watch a clean, uncluttered appearance.

Historical and Technical Background:

This watch is based on a 1980 UK MOD specification for automatic diver's watches (DEF STAN 66-4 [Part 1] Issue 3). This specification called for a unidirectional bezel and a boldly marked dial with tritium paint and a mineral glass crystal. Although this watch is made in the spirit of the 1980 watches, it includes improvements such as the sapphire crystal and increased water resistance.

Benefits of Sapphire Crystal:

Many customers ask about the benefits of sapphire crystal over standard mineral 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 are then coated with two layers of anti-reflective coating. While sapphire crystals are more expensive, they offer superior longevity, resilience, and performance, justifying their use in higher-end watches.

These models represent excellent value and are very competitively priced for such a high-performance automatic watch. This watch combines the historical design and functional integrity of its predecessors with modern upgrades to meet the needs of today's 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 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.
