Based on the Big Bang Unico Black Ceramic, the Big Bang Unico Ledger has a 42mm black ceramic case and a skeletonised automatic chronograph in-house movement.
Its high-contrast golden bezel is 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.
