Swiss Sapphire is the 2nd hardest transparent substance in earth after diamond. Our sapphire crystal comes from the best Swiss factory that produces top-quality boules for Rolex too. So we basically we use the same crystal as Rolex!
Our sapphire crystals have correct 2 5X magnification Cyclops lenses over date and a laser-etched tiny Rolex crown inside the crystal above the 6 Oclock. This tiny laser-etched Rolex crown detail is very hard to see with the naked eye but is visible using a magnifying glass or loop.
