Why Sapphire Crystal?
Many people ask what makes sapphire crystal superior to standard mineral glass. The answer is simple — synthetic sapphire is the strongest and most scratch-resistant material used for watch crystals. These qualities make it especially popular with military personnel, police officers, security professionals, and outdoor enthusiasts — groups that together account for over 70% of our customers.
Our experience shows that when customers damage a crystal, over 90% of the time it’s mineral glass, even when hardened. Sapphire crystals, by contrast, can withstand far greater stress and impact.
Their strength comes from the manufacturing process: after formation, the sapphire glass is heat-treated to remove internal stresses that could cause weakness. It is then shaped into the finished crystal and coated with two layers of anti-reflective material for maximum clarity. Interestingly, the same sapphire technology is now used on the latest iPhones.
While sapphire crystals cost more to produce, they offer unmatched durability and scratch resistance — a key reason why they are fitted to higher-end timepieces.
