big bang tourbillon only watch


Since 2005, Hublot has been committed alongside ONLY WATCH to help research to overcome Duchenne muscular dystrophy one day and protect future generations. How? By creating a unique piece every two years—that is sold at auction with all profits going to the association—for which the singular alchemy generally sends the bids off the scale. Beyond the technical prowess of the piece and its innovation, it is the reason behind the fund raising that has been motivating the watchmakers for so many years to surpass themselves so that the exceptional can bring an end to the unacceptable: the illness.


This year, the unique piece is called Big Bang Tourbillon Only Watch. Its translucent case cut from sapphire and its orange bezel display the expertise of Hublot and the colour code for ONLY WATCH 2021. The dial, which is also made from sapphire reveals the mechanics of the new self-winding manufacture tourbillon movement—MHUB6035—launched in January. Still in the same tones:  A raised section, Superluminova on the hour and minute hands, and the numerals are also orange coloured. The watch is engraved with “Pièce Unique” and the Only Watch logo on the sapphire back cover and comes with two interchangeable One Click structured lined rubber straps, one of which is transparent and the other is orange.

“Hublot & Only Watch is a story that began in 2005; it is a noble purpose, a willingness to combine our strengths to fight against the illness, to push back our limits and beat records for a good cause. For this 9th edition, we have fused together in a unique piece our iconic model—the Big Bang—with one of our flagship innovative materials—sapphire—a translucent sapphire case and a bezel in one of the colours that is the most difficult to produce—orange, and an innovative movement—our new self-winding tourbillon and its 3 sapphire bridges. A complex, polarising piece, which is simultaneously powerful, positive and inspiring and combines the best of Hublot for a good cause!”

We no longer need to present the Monegasque Association against Muscular dystrophy, founded in 2005 by Luc Pettavino and placed under the patronage of H.S.H. Prince Albert II of Monaco.

Every two years, dozens of watchmakers produce a unique piece. They put their expertise and their innovation at the disposal of the Association to raise funds. Since 2005, Hublot has produced 8 unique pieces specifically for the Association’s auction and is unveiling its 9th creation today. On 6 November this year, the Big Bang Tourbillon Only Watch will go under the hammer at Christie’s to be transformed into a donation for research into Duchenne muscular dystrophy


The Big Bang Tourbillon Only Watch

A unique piece cut in sapphire—translucent and orange—with the iconic design of the Big Bang and revealing the mechanics of the self-winding tourbillon manufacture movement with sapphire bridges.


Sapphire, a material that no longer holds any secrets for Hublot

Its transparency hides nothing, everything is laid bare and the watchmaker knows how to produce this ultra-resistant and tough material in almost every colour without losing its clarity and its purity. To create its bezel in orange sapphire, Hublot once again added a world first to its list of records. Solution-dyed sapphire, in a powerful orange, which is vibrant and positive, resulting from the fusion of titanium and chrome, and that follows the Only Watch codes. To make the most of this unique piece with its total transparency, Hublot has decided to reveal everything and hide nothing, right down to the chassis itself, which is entirely cut in sapphire. This means that the Big Bang Tourbillon Only Watch can be admired like a work of art, from any angle, from your wrist to its frame.


The MHUB6035, a self-winding manufacture movement

Whereas standard tourbillon movements are manual winding, the MHUB6035 calibre, which was entirely developed and designed by the Hublot Manufacture, is self-winding. Its sunray-brushed and sandblasted angled micro-rotor in 22-ct white gold is visible on the dial side, creating a spectacular and sophisticated impression. Playing with the ultimate transparency of the case and the strap, right down to the movement, Hublot has also included sapphire in the calibre itself by equipping it for the first time with three sapphire bridges—the barrel bridge, automatic watch bridge and tourbillon bar.


A unique piece that is innovative from the case to the movement The Big Bang Tourbillon Only Watch could once again be the focus of all the attention and beat new records at the auction. Watch this space…
