The Tourbillon Black & Gold, issued in a 20-piece limited edition, features a 48 mm-diameter XL case appearing in this refined two-tone interpretation. The black background elegantly clothes the surfaces with their cleverly structured volumes. Rose gold enlivens the overall effect in a delightfully understated way, forming a perfect circle around the tourbillon, the dauphine hands and the baton-shaped hour-markers. The lugs merge seamlessly into the rubber strap, further emphasizing the purity of this creation.
