Official description

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.
