GS Supplies - Mineral Glass Watch Crystals

G-S Mineral Glass Watch Crystals

Mineral Glass is one of the most popular and common materials used for watch crystals today. Its fine reflective characteristics, its strength and clarity, and its reasonable pricing make it a popular choice for watch manufacturers and for the watch repair industry. G-S was the originator of the term "MG" to refer to mineral glass. This term is now used throughout the watch repair industry by watchmakers, jewelers, and watch material experts.
