Hublot Big Bang Unico King Gold Pave 44mm 421.OX.1180.RX.1704 - BRAND NEW

The Hublot Big Bang Unico King Gold Pavé 421.OX.1180.RX.1704 is one of the most opulent expressions of a watch family that has defined 21st-century luxury sport watchmaking. Introduced in the early 2000s, the Big Bang quickly became Hublot's flagship line, celebrated for its bold 'Art of Fusion' philosophy — an approach that marries unexpected materials, avant-garde engineering, and fine jewellery craftsmanship into a single cohesive design. The King Gold case material is central to that philosophy: it is an 18k rose gold alloy developed exclusively by Hublot's metallurgists, engineered to be harder and more scratch-resistant than standard 18k gold while retaining the warm, rich hue that makes precious metal watches so desirable. At 44mm in diameter, this reference makes an emphatic statement on the wrist without sacrificing wearability.

The case architecture of the Big Bang Unico is immediately recognisable. Twelve H-shaped screws punctuate the mid-case, echoing the industrial aesthetic that sets Hublot apart from more traditional maisons. On reference 421.OX.1180.RX.1704 the bezel is entirely set with diamonds, creating a continuous halo of brilliance that frames the dial and elevates the watch from sporty chronograph into genuine high-jewellery territory. The interplay between the textured King Gold case flanks and the pavé diamond bezel is a study in contrasts — raw strength meeting refined sparkle — and it is precisely this tension that has made diamond-set Big Bang references perennial bestsellers.

The black dial is the ideal canvas for the Big Bang Unico's skeletonised or open-worked aesthetic. Hour markers rendered as polished indexes alongside bold Arabic numerals ensure immediate legibility, while the sub-dials and chronograph indications are thoughtfully integrated into the overall composition. The combination of a dark dial with the warm glow of King Gold and the icy flash of diamonds is a palette that reads powerfully in any light, whether under boardroom fluorescents or evening candlelight.

Powering the watch is an automatic movement from Hublot's Unico manufacture calibre family — an in-house developed column-wheel flyback chronograph movement that reflects the brand's significant investment in vertical integration since the late 2000s. The Unico movement is visible through the exhibition caseback, revealing the intricate architecture of a contemporary manufacture calibre and reinforcing that this is not merely a jewel-set dress watch but a serious piece of horological engineering. The black rubber strap — another Big Bang signature — keeps the overall ensemble grounded in sport-watch DNA, and Hublot's one-click interchangeable strap system means it can be swapped effortlessly.
