Non scratch Sapphire crystal is use on all our Rolex Replica watches. Chemically the same as sapphire used in jewelry, but without the coloring agents that gives the gem stone its various hues, sapphire crystal is one of the hardest substances on earth. It measures 9 on the Moths scale (Diamonds measures 10) and is virtually impossible to scratch unlike Mineral glass found on cheaper replicas. The crystal also include a perfect laser etched crown at the “6” O’clock to replicate the original . All date magnifications on our Replica Rolex watches are 100% correct on every model. We also instal anti-reflective Sapphire crystal on certain models, these are coated on one or both sides when applicable.
