Piaget’s Emperador Temple diamonds watch has Lil Wayne written all over it. Essentially two-watches-in-one, one face is concealed by in a case covered in 481 brilliant-cut diamonds, 207 baguette-cut diamonds, and an emerald-cut diamond. While on the second face the Polynesian mother-of-pearl dial has 162 brilliant-cut diamonds, 11 baguette-cut diamonds and a bracelet set with 350 baguette-cut diamonds. The watch was a one-of-a-kind and was gone as soon as it was released.
