Needless to say the Cooper Submaster exudes the style of the indestructible divers watches worn by the British special forces in the 1970s and 80s. A functional form that doesn't date, and always has a classic style for divers watch aficionados.

The Submaster is a British-designed quartz date military divers watch. Traditional stainless steel finish complete with high quality 20mm. The black dial is enhanced with Submaster in white and retro military Gladiator Hands. Fully waterproof to 300m/ 1000ft pressure tested. The matte finish on the case gives the watch anti-reflective qualities when on daylight missions.The special Gladiator Hands are designed for much better visibility under low light conditions, either underwater or on night operations. The bezel insert is equipped with full 60 individual minute markers, this was originally designed so that military frogmen would be able to synchronize perfectly on dangerous covert missions.

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%are 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.
