January 19th, 2026 – Milan, Italy – Hublot and British Designer Samuel Ross MBE, strengthen their design partnership with the debut of the Big Bang Unico SR_A, the first signature SR_A model equipped with the Manufacture’s Unico chronograph calibre.

With the Big Bang Unico SR_A, Hublot and Samuel Ross open a new chapter in their partnership. For the first time, the SR_A design language is paired with the Unico Manufacture movement, bringing Ross’s industrial codes and Hublot’s most emblematic chronograph calibre together in one unified creation.

Limited to 200 pieces, the timepiece adopts a monochrome ceramic exterior and a newly developed honeycomb rubber strap, refining the design vocabulary established by the three previous SR_A tourbillon editions. Combining ceramic engineering, industrial geometry and the performance of the Unico movement, the Big Bang Unico SR_A offers a more widely available expression of the collaboration while remaining firmly anchored in Hublot’s Art of Fusion and Ross’s distinct identity.

The Big Bang Unico SR_A represents the evolution of a partnership built on structure, material innovation and contemporary industrial design. Since 2020, Hublot and Samuel Ross have developed a distinctive creative language through three SR_A Tourbillon editions.

The watch features a 42mm case in satin-finished and polished black ceramic, reflecting the bold geometry and modular construction of the Big Bang line. The choice of an all-black ceramic execution brings the SR_A back to a sleek, stripped-back aesthetic.

At the centre of the design is Samuel Ross’s signature honeycomb motif. Seen previously in the SR_A sculptures and earlier watch limited editions, the pattern appears here on a newly developed structured rubber strap created specifically for this reference. Lightweight, ergonomic and strongly architectural, it reinforces the industrial character of the SR_A series. “With the honeycomb, it was about taking information away from the watch to increase the lightness,” explains Ross.

The matte black skeleton dial exposes key Unico components, including the visible column wheel at 6 o’clock and the open chronograph mechanism. This transparency highlights the technical architecture of the HUB1280 calibre, which incorporates a flyback chronograph, silicon escapement and a 72-hour power reserve.

The move to a 200-piece limited edition marks a deliberate broadening of the collaboration. While earlier SR_A models were produced in smaller runs and centred around sculptural tourbillon constructions, the new Big Bang Unico SR_A introduces the artist identity into a more obtainable, more versatile format, aligning the partnership more closely with the wider Big Bang collection.

“The Big Bang Unico SR_A brings together our most recognisable in-house movement and Samuel Ross’s design philosophy. It also represents an important milestone for Hublot as this year we celebrate the 20th anniversary of our first All Black timepiece, making this edition with Samuel Ross even more special for us. It represents a natural development of our collaboration - more open, more accessible, and driven by the same commitment to innovation that has defined the SR_A story from the beginning”

“Stealth, Strength - speed. Our first signature SR_A HUBLOT chronograph advances our design dialogue across London and Geneva. Deeply functional, robust and hard wearing, we have envisioned a new wearable machine for the wrist built for a rugged, hands-on lifestyle. A completely new casing of black ceramic re-shaping Hublot’s Iconic Unico movement. We are deeply committed to advancing the expectations of what modern watchmaking represents through radical design and distinct precious metals.”

With its combination of an all-black ceramic exterior, the SR_A industrial codes and the Unico calibre, the Big Bang Unico SR_A sets a new benchmark within the partnership and reinforces Hublot’s position at the crossroads of watchmaking, design and contemporary culture.
