From the first use of rubber in watchmaking to creating new precious alloys, such as scratch-proof Magic Gold, and producing revolutionary composites like ceramic and sapphire with unique colors, materials are always at the heart of the Hublot universe.
The present example is first-time to the auction. “Hublot Spirit of Big Bang Sapphire Tourbillon “is a limited edition of 18 pieces for the Japan market, the sapphire barrel-shaped case with skeleton tourbillon manual winding movement.
Hublot used four blocks of machined sapphire to create this transparent version of the case — a very difficult process made all the more challenging by the unusual shape; according to the company, new machines and new processes to polish and finish components needed to be developed. The resulting case, after almost 100 hours of work involving 3D machining, is one that is as hard and nearly as scratch-resistant as diamond (sapphire is 9 on the Mohs hardness scale; diamond is 10), whose crystal clear design offers an unimpeded view of the skeletonized.
