At the heart of Tissot’s sapphire glass lies a fusion of skill and artistry. Using the Verneuil or EFG method, alumina oxide powder is fused at extreme temperatures to create synthetic sapphire, one of the hardest materials available. With a Vickers hardness of 2,000–2,200, sapphire glass offers exceptional scratch resistance and guarantees a perfectly transparent surface, showcasing the dial and hands in their full beauty. | Tissot
