Sapphire is the material on which our business is built. Erma Boécourt SA transforms this noble material into watch crystals. We make the different materials, substances and products required for processing the components, enabling us to control the machining process from start to finish without having to rely on third-party companies. Erma Boécourt SA therefore enjoys genuine independence in the sector, aided by its efficient organisational structure.
