An abbreviation which stands for Physical Vapour Deposition. The PVD technology used in Oris watches and bracelets is one of the most up-to-date and non-polluting coating systems. In the case of gold-plating, its quality can be compared to 10-micron gold-plating. The PVD finish is highly scratch-proof and long-lasting. The authentic gilt colour tone is obtained by applying a 23-carat gold layer. The primary desirable qualities of PVD coatings are hardness, durability and anti-allergenic properties.
