Hublot’s Big Bang Reloaded makes the Unico chronograph’s workings part of the dial

The Big Bang Reloaded reorganises Hublot’s openworked chronograph around specific views of its Unico mechanism. Dial openings highlight the column wheel, clutch and central gear train, while greater contrast makes the counters easier to distinguish. The date moves away from the main counter to approximately four-thirty.

The 44mm case measures 14.5mm thick and is rated to 100 metres. Two straps use the One-Click exchange system, while the automatic movement retains flyback timing. April launch coverage listed titanium, ceramic and Magic Gold versions, with the blue ceramic shown here at $25,200. Separate Usain Bolt and Kylian Mbappé editions add athlete-specific details and limited production.
