Corundum

Corundum

Is a crystalline form of aluminum oxide, and it exists in its pure form as a rare, colorless variety known as white sapphire. It is characterized by its high hardness and is used in the production of reflective glass and scratch-resistant glass. In watchmaking, corundum is used to create the front and back glass to protect the dial or various parts of the watch from damage and scratches, as it is one of the hardest materials after diamond in terms of hardness.

Additionally, corundum exhibits high chemical resistance and good transparency, making it an ideal material for glass manufacturing in watches.
