Hublot Big Bang Unico King Gold Blue Skeleton 45mm Dial Bezel Rubber Strap 411.OX.5189.RX - BRAND NEW

The Hublot Big Bang Unico 411.OX.5189.RX is one of the most visually arresting references in the entire Big Bang lineup, bringing together the brand's signature King Gold case material, a blue-tinted skeleton dial, and the powerful in-house UNICO chronograph movement in a bold 45mm package. Since Hublot introduced the Big Bang in 2005, the collection has defined a new vocabulary for luxury sport watchmaking — one built on the philosophy of fusion, pairing noble metals with cutting-edge materials in ways that were previously unthinkable in traditional horology.

King Gold is Hublot's proprietary 18-karat rose-gold alloy, developed in partnership with metallurgists to achieve a harder, more scratch-resistant surface than conventional gold while retaining the warm, deep luster that collectors prize. On the 411.OX.5189.RX, the 45mm case is crafted entirely from this material, giving the watch a commanding wrist presence that feels simultaneously precious and robust. The integrated King Gold bezel amplifies the monochromatic richness of the design, framing the dial with an architectural solidity that is unmistakably Hublot.

The blue skeleton dial is the centrepiece of this reference. Rather than hiding the movement behind a conventional face, Hublot's designers have opened the dial entirely, skeletonizing the bridges and mainplate and finishing them with a vivid blue treatment that draws the eye deep into the movement. Index hour markers and Arabic numeral accents provide legibility without compromising the theatrical, mechanical spectacle beneath. The result is a dial that rewards extended scrutiny and looks equally stunning in daylight and low light.

Powering the 411.OX.5189.RX is Hublot's UNICO manufacture calibre, a column-wheel flyback chronograph movement developed and produced entirely in-house at Hublot's La Chaux-de-Fonds manufacture. The UNICO was a landmark achievement for Hublot when it debuted, demonstrating the brand's commitment to vertical integration and genuine manufacture credentials. Its column-wheel and horizontal clutch architecture deliver precise, smooth chronograph engagement, and the movement is visible through both the open skeleton dial and the exhibition caseback. A black rubber strap with the characteristic Hublot one-click system completes the package, offering quick interchangeability and a sporty, comfortable fit against the wrist.
