Synthetic sapphire is by far the best material for watch crystals due to its exceptional strength, shatter resistance, and scratch resistance. These characteristics make it highly appealing to military and security personnel, police officers, and people who lead active outdoor lifestyles—groups that account for over 70% of our customer base. In our experience, over 90% of incidents involving cracked watch crystals occur with mineral glass. Even hardened mineral crystals do not match the durability of sapphire. Sapphire crystals are strengthened through a heat treatment process that removes internal stresses, followed by the application of two layers of anti-reflective coating. Although sapphire crystals are more expensive, they offer superior longevity, resilience, and performance, justifying their use in higher-end watches. This watch combines historical design and modern functionality, making it an exceptional choice for professionals and enthusiasts alike. Its robust features and user-friendly design ensure it meets the demands of today's discerning watch wearers.
