Hublot’s newest watch is a paragon of transparency. It’s called the Big Bang Integral Tourbillon Full Sapphire, and the Swiss firm revealed it at this 2021 Watches & Wonders horological extravaganza in Shanghai.

Full transparency in China? You heard it here first.

The watch is a beaut, and it is as ‘full sapphire’ as it’s possible for a watch to be; perhaps beyond the limits of expectation. The watch case is sapphire—a tricky business in and of itself—but the band, too, is fabricated from the fine synthetic crystal, and there are no visible metal connections.

There are 37 components in this tourbillon timepiece. The caliber is Hublot’s HUB6035 micro-rotor-based automatic, and it comes with a power reserve of 72 hours. The case measures in at 43mm.

The Bang Integral Tourbillon Full Sapphire from Hublot is priced at $422K. Only 30 will be produced.
