SARO-Gem Jewellery Watch Co., Bettlach, Switzerland, has found a new use for synthetic sapphire in watches. SARO, which stands for Sapphire Round Over, uses synthetic colorless sapphire not only as the crystal over the dial but also as an overlay on the bracelet itself, making the entire watch scratch reistant. Sapphire rates 9 on the Moh's hardness scale. In a process called physical vapor deposition (PVD), transparent sapphire plates are coated with particles of white or yellow gold, palladium, or a pigment (sapphire blue, emerald green, ruby red, aubergine, or black).
