Hublot Spirit of Big Bang Sapphire has a barrel shaped case measuring 45 mm wide and 15.10 mm thick. 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, self-winding movement, Caliber HUB4700.
Based on the famous El Primero from Zenith, Hublot’s sister brand within the LVMH luxury group, the movement has an integrated chronograph, a visible date wheel with the current date displayed in an aperture at 4:30, a high-balance frequency of 36,600 vph, and a power reserve of 50 hours. Aside from the movement components, the very few non-sapphire elements visible on the watch are the crown, chronograph pushers, case screws, H-shaped bezel screws, and the deployant buckle clasp, all made of titanium.
Limited to 250 pieces and mounted on a structured, lined rubber strap, the replica Hublot Spirit of Big Bang Sapphire is priced at $79,000. Best cheap watches online, discover our affordable replica Hublot Spirit of Big Bang Sapphire watches collection. Wide range of luxury watches brands.
