Sapphire glass - Never again scratches
All LOUIS XVI watches feature a scratch-resistant, double-sided anti-reflective sapphire crystal. A quality feature of which we are very proud. Sapphire crystal is much harder and more scratch-resistant than the mineral glass often used in conventional watches. Sapphire crystal cannot be scratched through everyday use. If it were solely about technical advantages, probably every manufacturer would equip their watches with sapphire crystal today. However, not every manufacturer does this - because the high quality comes at a price. The production of sapphire crystal is very time-consuming and expensive.
