WHERE SUBSTANCE MEETS CLARITY
Polycarbon Sapphire
The bezel is crafted from sapphire crystal, a highly durable material with a hardness of 9 on the Mohs scale—second only to diamond. Known for its exceptional scratch resistance and optical clarity, sapphire offers superior protection against wear while maintaining a pristine, glass-like appearance over time. Its high transparency enhances the aesthetic of the timepiece, while its chemical stability ensures resistance to UV radiation, thermal shock, and environmental corrosion.
