Most of the watch crystals that we produce are coated using anti-reflective technology by our long-standing partner Econorm, based in Gams and St Imier. Our sapphire crystals are coated using different procedures:
- Single-layer: the sapphire is coated with a very fine layer.
- Multi-layer: this traditional multi-layer coating employs leading-edge technology and offers a more robust coating that is easy to clean and has good resistance to chemical products.
- ARdur anti-reflective: this process strengthens the protective layers and renders the material elastic to prevent it from chipping under impact.
- Top coat: this type of coating adds a very fine, smooth layer over an existing coating, which helps to keep the crystal clean. This highly durable coating uses hydrophobic technology to prevent oil and grease from adhering to the crystal, making it easy to clean with a damp cloth.
By working with the very best partners in the industry, our family firm has been able to constantly build on its expertise and ensure that it always supplies products of the highest quality.
