WISeKey and Jean-Claude Biver confirm NFT sale extension as bidding bubble grows


Jean-Claude Biver and Swiss cybersecurity company WISeKey International Holding Ltd have extended the first historic NFT auction of a luxury watch until the end of April.

Kick-off of the extended NFT auction will be April 7th, 2021 at 9.00 AM CET from here and will end April 30th, 2021 at 6PM CET.

The winner of the auction will take ownership of the digital twin of Jean-Claude Biver’s Bigger Bang All Black Tourbillon Chrono “Special Piece” watch, a timepiece that served as a reference for tourbillons and complicated models released during his time at Hublot.


The NFT auction will mean the physical watch will remain as part of Biver’s personal collection.

Bidding for the incorruptible digital file of the watch has reportedly reached 25 ethers ($52,825 at the current ether to dollar exchange rate).

Ether is a blockchain-based cryptocurrency similar to Bitcoin.
