Hublot Big Bang Unico Integrated King Gold 42mm 451.OX.1180.OX - BRAND NEW

The Hublot Big Bang Unico Integrated in King Gold, reference 451.OX.1180.OX, is one of the most complete expressions of what Hublot has built its reputation on: bold, avant-garde horology wrapped in precious materials that feel anything but conventional. Presented here brand new, this 42mm timepiece occupies the sweet spot of the Big Bang Unico collection — large enough to command attention yet measured enough to wear with genuine versatility across a wide range of occasions.

King Gold is Hublot's proprietary 18k rose gold alloy, developed in-house to deliver a richer, deeper warmth than standard 18k rose gold while offering superior resistance to fading and oxidation over time. Every surface of this reference — the 42mm case, the bezel, and the fully integrated bracelet — is rendered in this exclusive material, creating a monolithic continuity that distinguishes the 451.OX.1180.OX from any Big Bang reference that mixes materials or pairs gold with rubber. The result is a watch that feels simultaneously opulent and purposeful.

The black index dial provides precisely the contrast this case demands. Clean applied hour markers catch the light against the dark background, ensuring legibility at a glance without compromising the watch's dressy character. The Big Bang Unico's signature open-worked architecture is visible through the dial, offering a glimpse of the movement's mechanical complexity and reinforcing Hublot's philosophy of the Art of Fusion — where fine watchmaking and bold design coexist on equal terms.

Powering the 451.OX.1180.OX is Hublot's UNICO manufacture chronograph movement, a column-wheel flyback chronograph caliber developed and produced entirely within Hublot's own facilities in Nyon, Switzerland. The UNICO movement is visible through the exhibition caseback, showcasing its architecture to those who appreciate what drives a true manufacture timepiece. It is a movement built to perform as impressively as it looks, and its in-house origins add meaningful depth to the watch's value proposition.

On the wrist, the integrated King Gold bracelet transforms what might otherwise be a substantial 42mm case into something remarkably wearable. The bracelet's links taper gracefully toward the deployant clasp, hugging the wrist and distributing the watch's weight evenly. This integrated design language — where the bracelet feels architected alongside the case rather than simply attached to it — is a hallmark of the Unico Integrated line and one of the primary reasons collectors seek this specific configuration over traditional strap-mounted references.
