The components used, such as the scratch-resistant transparent anti-reflective sapphire crystal, the carefully crafted stainless steel case that can withstand a pressure of 20 ATM and the precise Swiss automatic movement DAV 3021, ensure long-lasting functional reliability. The SuperLumiNova® BGW9 luminous material ensures outstanding lighting properties. In natural light, the best luminous material currently available is white; in the dark, it is clearly visible in a clear blue colour. The PVD plating (Physical Vapour Deposition) shines with the highest robustness and durability. In the PVD process, the watch case or bracelet is placed in a sealed high-pressure chamber in which the colour evaporates and creates a saturated atmosphere. As a result, the base materi
