Why Choose Sapphire Crystal?

Many customers ask about the benefits of sapphire crystal over a standard mineral crystal. Synthetic sapphire is the best material for watch crystals due to its exceptional strength and resistance to shattering and scratching. These characteristics make it ideal for military and security personnel, police officers, and individuals with active outdoor lifestyles, who make up over 70% of our customers.

When accidents result in cracked crystals, over 90% involve watches with mineral glass crystals. Even with hardened mineral crystals, they do not compare to sapphire for durability under adverse conditions. Sapphire crystals are strong because they undergo a heat-treatment process that removes internal stresses, which can cause weakness. After manufacturing, the sapphire glass is made into watch crystals, and two layers of anti-reflective coating are applied. Interestingly, sapphire crystal is now used on the latest iPhones. Due to its higher cost, sapphire crystal is typically found only in higher-end watches.
