Hublot Big Bang Unico Integrated Yellow Gold Jewellery 42mm 451.VX.1130.VX.9804 - BRAND NEW

The Hublot Big Bang Unico Integrated Yellow Gold Jewellery reference 451.VX.1130.VX.9804 stands at the summit of Hublot's watchmaking ambition, uniting the brand's signature fusion philosophy with the dazzling language of high jewellery. Since its introduction, the Big Bang collection has redefined what a luxury sports watch can be — bold, architectural, and unapologetically expressive. The Unico designation elevates that vision further by anchoring the watch around an entirely in-house manufacture movement, a point of pride that distinguishes it from countless competitors in the luxury space.

At 42mm in yellow gold, the case occupies a commanding yet wearable position on the wrist. Yellow gold has long been associated with the pinnacle of horology, and Hublot deploys it here not merely as a material choice but as a design statement — warm, luminous, and unmistakably precious. The diamonds set into the bezel amplify that radiance, each stone carefully selected and positioned to catch the light from every angle and to frame the black index dial with brilliant contrast.

The dial itself is rendered in black with index hour markers, a composition that serves both aesthetic and legibility purposes. Against the glittering diamond bezel and the yellow gold surround, the dark dial creates a visual depth that draws the eye inward toward the movement architecture visible through the openworked bridges — a hallmark of the UNICO caliber's design. The overall effect is of a watch that is simultaneously a jewel and an instrument.

The integrated yellow gold and diamond-set bracelet is perhaps the most impressive single element of this reference. Rather than attaching a separate bracelet to the case, Hublot has engineered a flowing connection between case and bracelet that reads as one continuous jewellery piece on the wrist. This level of integration demands extraordinary precision in both gem-setting and metalwork, and the result is a bracelet that sits flush, drapes naturally, and feels as comfortable as it looks extraordinary. For collectors and connoisseurs who admire the integrated-bracelet sports watch as an art form, this reference delivers that ideal in the most extravagant possible terms.

Powering the 451.VX.1130.VX.9804 is Hublot's own UNICO flyback chronograph manufacture movement, visible through the sapphire caseback. The UNICO caliber is a landmark achievement for Hublot — a skeletonized, column-wheel flyback chronograph developed entirely in-house, offering the technical sophistication that serious collectors demand. The movement's architecture is designed to be appreciated visually as well as mechanically, adding an intellectual dimension to what is already a visually spectacular watch.
