MWC 21 Jewel 1980s Pattern 300m Automatic Military Divers Watch with Sapphire Crystal and a Black and a Grey NATO Strap
Product Code: SUB/MILSSAU/MY
These divers watches are a remake of a 1980’s model which we made up until around 35 years ago, the watch has a robust stainless steel case and is equipped with a high-performance automatic 21 jewel self-winding movement. We have made a number of upgrades to the original watch such as the shatter and scratch-resistant sapphire crystal and increased water resistance rating. The dial and caseback are both unbranded (referred to in the military as sterile) which gives the watch a very clean appearance with a totally uncluttered face.
These models represent excellent value and are very competitively priced for such a high-performance automatic watch of this type.
This watch measures 45mm including the crown and 40mm excluding the crown and uses Luminova for first-rate nighttime visibility, the strap is a standard 20mm NATO strap as used on a wide variety of military divers models so there are a substantial range of colors options available if you like to occasionally change the strap which you are using.

* A lot of people ask us what are the benefits of sapphire crystal over a standard mineral crystal? The answer is that synthetic sapphire is by far the best material for watch crystals because it is very strong and also shatter and scratch-resistant, these characteristics make it very appealing to military and security personnel, police officers, and people who lead active outdoor lifestyles, these groups account for over 70% of our customers. To get things into perspective we find that when clients have accidents with watches resulting in a cracked crystal over 90% usually watches with mineral glass crystals, even factoring in that we use hardened mineral crystals they still do not come close to sapphire for durability under adverse conditions. The reason that sapphire crystals are so strong is that after the sapphire glass is manufactured it is also heat-treated to remove its internal stresses—which can cause weakness—it is then made into the watch crystals and two layers of anti-reflective coating are applied, interestingly sapphire crystal is now used on the latest iPhone. Of course, sapphire crystal comes at a price hence you find that it's normally only fitted to higher-end watches.
