There is no difference between mineral glass and sapphire glass, and both are suitable for the production of watch dial covers.sapphire crystal glass watches  Sapphire crystal or sapphire glass has become a favorite material for high-end watch mirrors because of its hardness, wear resistance and high light transmission.

Mineral crystal glass can be manufactured in various shapes, but sapphire crystal glass is only limited to a flat surface, such as the back of a mechanical watch. It depends on which style of watch you like, whether you prefer a traditional watch or a fashion watch. The style determines your needs.

Sapphire glass generally refers to synthetic sapphire, which is different from the jewelry that people usually understand-natural sapphire, and is generally used for the manufacture of watch mirrors.

Mineral glass resists falling from a height, resists impact on the sapphire mirror, resists the mirror surface being scratched, and is required for wear resistance.
