Class One Tourbillon by Chaumet

The Class One, endowed with a tourbillon escapement mechanism, considered to be the most ingenious of watchmaking complications, is adorned with a breath-taking array of precious stones. Each watch is embellished with an exceptional selection of 558 stones representing a total weight of over 25 carats. There are two unique pieces; diamond and blue sapphire or diamond and ruby and two limited editions of four pieces each in white diamonds and black diamonds. Each version presents an XL size 42 mm case in white gold which is entirely set with calibre baguette-cut stones from the bezel to the side of the case, including the horns and crown.
