Hublot Big Bang Chrono Perpetual Calendar

For the 10th anniversary of the Big Bang Chronograph, Hublot have presented their first perpetual calendar chronograph, a watch that also includes a chronograph and a moon phase display. The information is combined on the dial in a design that expresses complexity, with skeletonized movement visible beneath the sapphire dial.


The subdials combine different functions and so the designers have used white hands for the perpetual calendar and red arrow-shaped hands for the chronograph. Correctors on the caseband are used to adjust the various calendar indications. The watch is in two versions, titanium or King Gold (a Hublot proprietary alloy of red gold and platinum). Something that doesn’t transpire from the photos shown here is the great impression of three-dimensionality created by the deep bezel and the many layers of dial and movement.



The watch is powered by the self-winding HUB 1270 UNICO movement, which provides a power reserve of about 72 hours. It is basically the same UNICO movement that Hublot developed in-house for the Big Bang chronograph, onto which they have added a perpetual calendar module by Dubois Depraz.
