Hublot Big Bang Tourbillon Automatic Orange Sapphire

They call themselves the Sapphire experts.. and rightly so! Building on the success of the Big Bang Unico Sapphire (transparent), All Black Sapphire, Big Bang Unico Red Sapphire and Blue Sapphire, and the recent Spirit of Big Bang Yellow Sapphire, Hublot unveiled the Big Bang Tourbillon Automatic Orange Sapphire at LVMH Watch Week 2021. This is the first time orange sapphire has been used in this manner and the result in sensational.

The orange shade on the 45mm sapphire case is achieved thanks to the incorporation of titanium and chromium in a skilful manufacturing process. This surprising and dynamic colour is a breath of fresh air for haute horlogerie, and is in perfect harmony with Hublot’s culture of excellence. The fascination of the translucent bezel and case in finely polished orange sapphire is enhanced by the technical tone of the six H-shape titanium screws that characterise the iconic Big Bang design. A beautifully finished transparent orange structured lined rubber strap with titanium deployant buckle clasp, completes the cutting-edge look of this 50 piece limited edition.

Hublot has fitted the Big Bang Tourbillon Automatic Orange Sapphire with an entirely new self-winding tourbillon calibre MHUB6035 which ticks at a frequency 3Hz and delivers a power reserve of 72 hours. The movement is equipped with ceramic ball bearings and the latest Hublot technical advances in its winding system. The manufacture has also reasserted its uniqueness by reconstructing the movement in its entirety in order to make the micro-rotor visible from the dial side. The perpetual movements of the micro-rotor set at 12 o’clock echo the rotation of the tourbillon, its regulating organ, positioned in perfect symmetry at 6 o’clock. The grey 22-carat gold micro-rotor is set off by exquisite decoration (bevelling, sunray-brushing and sand-blasting), as well as by signature Hublot openwork in the precious metal.

Hublot has also continued in its quest for transparency by using more sapphire in the movement itself. The manufacture calibre on the Big Bang Tourbillon Automatic Orange Sapphire is equipped for the first time with three sapphire bridges – a barrel bridge, an automatic bridge and a tourbillon barrette. The lightweight effect of the skeleton work is accentuated by heavily open-worked and sandblasted platinum. The tourbillon cage at six o’clock, revolving on its axis every minute to compensate for the pull of the earth on the movement’s direction, is distinctive for its pure geometry affording a glimpse into the mechanical heart of the model. The legibility of the open dial is enhanced by hands and indices with a luminescent coating.
