After successful launches of the MP-05 “LaFerrari” Sapphire and the Big Bang Unico Sapphire, Hublot now releases a transparent, sapphire edition of its Spirit of Big Bang timepiece which boasts an emblematic barrel-shaped case.
Unveiling all of its construction and its skeletonised movement, the Spirit of Big Bang in sapphire allows the ultra-lightweight and a minimalist style both visually and when worn.
The upper part of the case with the bezel, the two end caps and the lower part including the back and the crystal revealing the movement, are made from 4 blocks of machined sapphire.
The barrel shape of the case was an additional challenge, including the development of a new machine and new processes to polish its components while offering an optimal finish. This procedure was made all the more delicate since the total transparency of the sapphire tolerates no marks associated with the machining operations.
Thanks to 3D machining and almost 100 hours of work, the Spirit of Big Bang Sapphire is as hard and scratch-resistant as diamond (9 on the Mohs scale, versus 10 for diamond). The only visible elements that remain are the crown, pushers, case screws, the 6 H-shaped screws of the bezel and the deployant buckle clasp, cut from titanium, and the components of the movement.
Released in only 250 pieces, the Hublot Spirit of Big Bang Sapphire watch is waterproof to 50 metres.
