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.

In-Depth Review

# Editorial: Hublot Spirit of Big Bang 42mm Titanium

Since its 2014 introduction, this 42mm titanium chronograph has occupied a unique position in Hublot's lineup—stripped of the Big Bang's aggressive maximalism yet retaining the DNA that defines the manufacture. The Spirit of Big Bang distills the collection's signature design language into a more refined package: the tonneau case with its distinctive H-shaped titanium screws, the skeleton dial that reveals the HUB4700 caliber beneath, and the integrated black rubber strap with alligator leather accent. At just 14mm thick, the watch achieves surprising elegance for a chronograph, while the lightweight titanium case ensures comfortable wrist presence despite its 42mm diameter. The 50-hour power reserve and respectable 100-meter water resistance underscore its utility, though the skeleton dial remains primarily a visual statement rather than functional necessity.

This is a watch for the established collector who appreciates mechanical horology but finds traditional chronographs insufficiently distinctive. The ideal owner recognizes Hublot's engineering prowess without demanding avant-garde provocation; they value refined Swiss manufacture and are comfortable with the brand's premium positioning. The Spirit works equally well in the boardroom or at leisure—the titanium's matte finish and rubber strap suggest purposeful restraint rather than ostentation.

In the twelve-to-sixteen-thousand-dollar segment, competitors like the Omega Speedmaster Professional and TAG Heuer Carrera offer heritage and arguably superior movement finishing. Yet at current market rates around twelve thousand dollars, the Spirit presents compelling value for buyers seeking something architecturally bolder while maintaining legitimate manufacturing credentials.
