Sapphire Crystal is a highly scratch-resistant material used to make watch faces and protect them from damage. It is made from synthetic sapphire, which is an extremely hard material, second only to diamonds on the Mohs scale. Sapphire Crystal is the most expensive type of glass used for watch covers and is highly regarded for its durability, clarity and resistance to scratching. It is also resistant to chemicals, UV radiation and temperature changes, making it an ideal choice for watches.
