Sapphire, Mineral, K1, and Plastic Watch Glass
We produce watch crystals and gaskets in sizes ranging from 2.5 mm up to 250 mm. Sapphire, mineral, and plastic options are all supported. Sapphire crystals can be manufactured with thicknesses as thin as 0.2 mm, allowing for slim and refined watch designs. Plastic watch crystals can also be fitted with tension rings in multiple color options.
Our manufacturing process supports flat, curved, and shaped watch crystals for different case designs and technical requirements.

Mineral watch glass can be enhanced with several surface and finishing treatments, including:
- Anti-reflective coating for improved clarity
- Metallization for decorative or functional use
