* 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 strongB and alsoB shatter and scratch resistant, these characteristics make it very appealing to military and security personnel,B policeB 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 usuallyB 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 crystalsB are so strongB is that after the sapphire glass is manufactured it is also heat-treated to remove its internal stressesb which can cause weaknessb it is thenB made into the watch crystals and two layers of anti-reflective coating are applied,B interestingly sapphire crystal is now used on the latestB iPhone. Of course sapphire crystal comes at a price hence you find that it’s normally only fitted toB higher end watches.
