Hublot Spirit of Big Bang 42mm Titanium

About This Watch

The Hublot Spirit of Big Bang takes the iconic Big Bang design language and reinterprets it through a barrel-shaped or tonneau case, creating a watch that is unmistakably Hublot yet entirely distinct from its round-cased siblings. The 42mm titanium case — measured across the width of the tonneau — features all the signature Big Bang elements including the six H-shaped bezel screws, the sandwich case construction, and the multilayer dial architecture, but the elongated barrel shape gives these familiar elements a fresh and dynamic energy. The skeletonized dial reveals the HUB4700 automatic chronograph caliber, a movement specifically designed for the tonneau format with subdials repositioned to suit the longer dial aperture. With 50 hours of power reserve, the HUB4700 provides comfortable autonomy between wearings. The tonneau shape is one of the oldest case forms in watchmaking, with roots stretching back to the early 20th century, and Hublot's interpretation adds contemporary materials and manufacturing technology to this classic silhouette. The combination of alligator leather and rubber in the strap exemplifies the Art of Fusion philosophy, with the natural texture of exotic leather bonded to a rubber backing for comfort and water resistance. The Spirit of Big Bang appeals to collectors who love Hublot's design DNA but want something that stands apart from the ubiquitous round Big Bang on the wrist.
