This timepiece is made of over 1200 diamonds - baguette cut, brilliant cut, and one emerald cut stone on the top of the case, while its dial is made of Polynesian mother-of-pearl. The watch case is designed in a pyramid style "temple" design, and opens up twice, first showing watch face, and second showing a large face with an exposed one minute tourbillon and power reserve indicator. Its price, ‘a trifle’ - $3.5 million.
