Wonder where he got that one from,Sapphire crystals for watches are created in a laboratory environment and they have the same chemical properties as corundum which has a hardness of “9” on the Moh’s scale of hardness. (The only substance with hardness greater than sapphire is diamond which has a hardness of 10 on the Moh’s scale.) Because of their hardness, sapphire crystals were the most “scratch resistance” available in watches. However, sapphire crystals are prone to breakage due to the brittle nature brought about by its un-giving attributes no matter how they slice/cut them. Krysterna a new type watch crystal actually has more strength over a spread surface area than sapphire! this still is a very new synthetic material much like synthetic sapphire, but its much more shatter-resistant scratch resistant than plain sapphire it self.
