Hublot Big Bang Unico Integrated Yellow Gold Pave 42mm 451.VX.1130.VX.3704 - BRAND NEW

The Hublot Big Bang Unico Integrated Yellow Gold Pavé 451.VX.1130.VX.3704 represents the apex of what Hublot has built since Jean-Claude Biver relaunched the brand in the mid-2000s and introduced the original Big Bang in 2005. That first Big Bang fused a porthole-inspired case architecture with bold, interchangeable components and an unapologetically contemporary aesthetic, earning the Grand Prix d'Horlogerie de Genève and cementing Hublot's place among the most talked-about watch families in the world. The Unico designation adds an in-house movement story to that legacy, marrying technical ambition with the brand's signature Art of Fusion philosophy.

At 42mm in yellow gold, reference 451.VX.1130.VX.3704 occupies the sweet spot of the Big Bang Unico size range—substantial enough to command presence on the wrist yet refined enough to read as jewellery-forward rather than purely sporty. The yellow gold case is shaped in the recognizable Big Bang architecture: a multi-component mid-case, a prominent crown at two o'clock protected by characteristic H-shaped screws, and angular lugs that flow naturally into the integrated bracelet. Every surface has been finished with Hublot's characteristic combination of brushed and polished treatments, and the diamond-set bezel frames the dial with a halo of brilliance that catches light at every angle.

The black index dial is a deliberate and sophisticated choice. Against the warmth of the yellow gold case and the sparkle of the diamond bezel, the deep black surface creates a graphic counterpoint that keeps the watch legible and visually grounded. Applied hour markers and luminous hands read clearly across the dial, while the open-worked architecture that Hublot often employs in the Unico family allows a glimpse of mechanical depth. The overall effect is high-jewelry watchmaking that does not sacrifice readability or wearability for decoration.

The diamond-set integrated bracelet is the defining detail of this reference. Rather than a simple rubber strap or a plain metal bracelet, the 451.VX.1130.VX.3704 presents a yellow gold bracelet in which diamonds are pavé-set across the links, transforming what is structurally an engineering achievement—an integrated bracelet that flows seamlessly from the case—into an object of serious gemological value. The bracelet sits flush against the wrist, distributing weight evenly and contributing to the watch's polished, tailored wrist presence. This is a piece that works as confidently with formal evening attire as it does with the casual luxury wardrobe Hublot has always targeted.

Powering the watch is an automatic movement, the Unico caliber developed in-house by Hublot's manufacture in Nyon. The Unico movement is renowned within the brand's portfolio for its column-wheel flyback chronograph architecture and its skeletonized construction, which Hublot has consistently evolved since the caliber's introduction. Sourcing the movement entirely in-house reflects the brand's long-term commitment to verticalization and gives this reference genuine horological credentials to pair with its high-jewelry exterior.
