Hublot and Ledger present a unique partnership between watch craftsmanship and high-end crypto technology with Big Bang Unico Ledger

Watches & Jewelry


The Big Bang Unico Ledger, a 50-piece limited-edition landmark watch created in partnership with Ledger, is a game-changer and will go down in history as the first wristwatch to fuse fine watchmaking and high-end crypto technology perfectly together, paying tribute to the Maison’s ethos “Be First, Different and Unique”.

“The Hublot Big Bang Unico Ledger is a momentous collaboration that set the new standard for forward-thinking people who love watches, crypto and shaping the future” stated Ricardo Guadalupe, Hublot Chief Executive Officer.

This avant-garde is directly perceived in the package that contains three core elements: the watch, a limited-edition Ledger Nano X crypto wallet, and a special sapphire watch box. The watch is based on the Big Bang Unico, which has a 42mm black ceramic case and a skeletonised automatic chronograph in-house movement. Most striking is the watch’s high-contrast golden bezel, cast in solid “Electrum”, a natural gold and silver alloy that was used by Lydian societies in around 580-590 BC to mint the earliest known coins.


For the watch, Hublot’s R&D department developed a special stainless version of the alloy containing a 50/50 gold-silver mix. The Bitcoin Latin motto “Vires in Numeris”, or strength in numbers, is stamped six times into the bezel’s outer edge. Together, these themes capture the spirit of the world’s oldest and newest currencies. The case back is engraved with the Ledger logo and the 50-piece limited-edition number.

Packaged with the watch is the Ledger & Hublot Nano X, a limited-edition crypto key that will only be available with the watch. The Nano X is Ledger’s signature digital asset wallet, a market-leading Bluetooth-enabled piece of hardware for safely encrypting, securing, managing, and growing your crypto assets. The Nano X is finished in matte black and decorated with both Ledger and Hublot logos. These will be delivered in a special presentation box made of a transparent smoked black sapphire chosen to illustrate the transparency and security of blockchain and decentralised currency. The case also makes an ironic reference to the solid, once impervious nature of traditional vaults and safes, which serve no function when it comes to digital assets.


The theme of openness is transmitted seamlessly from the open working of the Big Bang Unico Ledger’s skeletonised dial, which showcases the watch’s elegant mechanical workings where normally they’d be obscured by a dial, through to the box and on into the world of cryptocurrency, and Ledger in particular, which has built its reputation on freely explaining how its technology works. “Hublot and Ledger both value creativity, scarcity and community. We are ecstatic to join forces with Hublot on this unique, timeless, extremely limited-edition watch. Our collaboration merges the oldest currency from ancient civilisations and cryptocurrency, in the same way that Hublot fuses innovative materials with horology” indicated Pascal Gauthier, Ledger CEO.

Between past and present, Hublot is fully committed to a visionary future based on traditional expertise. Thanks to the partnership with Ledger, a new era begins, where high-end crypto and state-of-the-art mechanical watchmaking meet. “This is the year when the watch industry will come to embrace crypto currency. Hublot has always been first, unique, different and we’re extremely proud and excited to introduce a luxury Swiss Made watch that brings these two passionate, creative worlds together in such an historic, tangible way” concludes Ricardo Guadalupe.
