Hublot Big Bang Unico Ceramic Magic Gold 44mm 421.CM.1130.RX - BRAND NEW

The Hublot Big Bang Unico 421.CM.1130.RX stands as one of the most compelling expressions of modern Swiss haute horlogerie, merging avant-garde materials science with a manufacture-level chronograph movement inside an immediately iconic 44mm case. First introduced as an evolution of the original Big Bang — itself launched in 2005 and widely credited with redefining the luxury sport watch category — the Unico variant elevated the line by replacing outsourced ebauches with Hublot's own in-house caliber, signaling the brand's maturation from bold newcomer to serious manufacture. Today the Big Bang Unico is considered a cornerstone reference for collectors who want genuine mechanical substance beneath the dramatic exterior.

The 44mm case of the 421.CM.1130.RX is crafted from black ceramic, a material Hublot has mastered through years of proprietary research. Ceramic offers an exceptional combination of properties: it is considerably lighter than steel, virtually impervious to surface scratching, hypoallergenic, and retains a deep, consistent color that does not fade or tarnish over decades of wear. The result is a case that looks as sharp on the wrist after years of daily use as it did the moment it left the manufacture in Nyon, Switzerland.

The bezel is where this reference truly commands attention, finished in Hublot's extraordinary Magic Gold. Developed in partnership with the École Polytechnique Fédérale de Lausanne, Magic Gold is the world's first scratchproof 18k gold, created by infiltrating a ceramic matrix with liquid gold under high pressure. The outcome is a bezel that carries the warmth, prestige, and precious-metal credentials of gold while defeating the one weakness that has always plagued the alloy — its susceptibility to scratching. On the 421.CM.1130.RX this contrast between matte black ceramic and lustrous Magic Gold is visually arresting and wholly unique in the market.

The black dial opens into the skeletonized architecture that defines the Unico aesthetic, allowing a direct view of the in-house Unico automatic chronograph movement below. Index markers and Arabic numerals provide confident legibility across the dial, balancing the technical, open-worked construction with practical readability. The watch is presented on a rubber strap that complements the sporting, high-performance character of the case while ensuring all-day comfort whether worn in the boardroom or on an active weekend.
