About this Watch
Hublot’s collaboration with Samuel Ross has always lived at the intersection of industrial design and horology, but the Big Bang Unico SR_A feels like the point where the partnership truly settles into its stride. Ross’s SR_A visual language is fused with Hublot’s in-house Unico chronograph, grounding the designer’s conceptual instincts in the brand’s most recognisable mechanical architecture.
Limited to 200 pieces, the watch pares things back with intent. A 42mm case in satin-finished and polished black ceramic gives the Big Bang’s modular geometry a stark, utilitarian edge, while the monochrome execution sharpens the focus on form and structure. The newly developed honeycomb rubber strap, an SR_A signature, adds a strong architectural rhythm, its negative space deliberately engineered to reduce visual mass and enhance wearability.
The skeletonised dial reveals the Unico calibre in full working honesty: column wheel at six, open chronograph works, flyback function and a 72-hour power reserve. It’s less sculptural than the earlier SR_A tourbillons, but that’s precisely the point. This is Ross’s design ethos translated into a more accessible, everyday Big Bang, still experimental, still uncompromising, but now speaking fluently in Hublot’s core mechanical language.
