Big Bang Unico Rainbow King Gold. In this regard, bright red, fuchsia pink, ultraviolet, dark blue, turquoise, chlorophyll green, lemon yellow and bright orange are combined on the bezel and 45 mm case to create an extravagant and in no way ordinary timepiece. To achieve this result, no less than 436 stones have been selected. Eight dazzling gemstones – rubies, pink sapphires, amethysts, blue sapphires, blue topazes, tsavorites, yellow sapphires and orange sapphires – are used in this daring chromatic creation.
