The Crystal Is the Window to Your Watch
The crystal is the most exposed part of any watch. Over time, its quality determines whether your watch still looks new or carries scratches across the dial.
What Is Mineral Glass?
Mineral glass is heat-treated standard glass. Most watches under €200 use it because it's cheap. After 6-12 months of regular wear, visible scratches appear — fine hairlines that catch the light and obscure the dial.
What Is Sapphire Crystal?
Sapphire crystal is synthetic corundum — the same material as a natural sapphire. It scores 9 on the Mohs hardness scale, making it the second hardest transparent material after diamond. Virtually scratch-proof in daily wear. This is why every luxury brand — Rolex, Omega, Grand Seiko — uses sapphire exclusively.
The Real-World Difference
After one year: mineral glass has visible scratches. Sapphire looks like day one. After three years, the difference is dramatic. For a watch costing €200+, sapphire should be standard, not a luxury upgrade.
Every CrownCraft Uses Sapphire
All six CrownCraft models use sapphire crystal as standard — the BELMONT, CENTRE COURT, DEEPMASTER, MERIDIAN-GMT, ROADSTER, and SPEEDWAY. Starting at €229.
