Hublot Big Bang Unico King Gold Diamonds 44mm 421.OX.1180.RX.1104 - BRAND NEW

The Hublot Big Bang Unico King Gold Diamonds, reference 421.OX.1180.RX.1104, represents one of the boldest expressions of modern Swiss haute horlogerie. Launched as part of the Big Bang family that Hublot first introduced in 2005, the Unico line elevated the concept further by housing a manufacture chronograph movement entirely developed within Hublot's Le Sentier workshops. The Big Bang has since become a cultural icon—equally at home on the wrists of athletes, collectors, and connoisseurs—and the King Gold diamond configuration sits confidently at the pinnacle of that lineage.

At 44mm, the case diameter is classic Big Bang territory: substantial enough to command attention without overwhelming the wrist. The case is fashioned from Hublot's proprietary King Gold, an 18-karat rose-gold alloy enriched with platinum and other elements to reduce oxidation and preserve its deep, warm hue over time. King Gold is exclusive to Hublot, making it a genuine point of differentiation for collectors who appreciate both rarity and metallurgical innovation. The H-shaped titanium screws—a hallmark of the Big Bang architecture—punctuate the case with an industrial precision that contrasts beautifully against the precious metal.

The bezel is set with diamonds, adding an undeniable layer of brilliance to the King Gold foundation. Diamonds on a Big Bang bezel are individually set to maximise light return, framing the dial with continuous sparkle. The dial itself is finished in black, providing a dramatic dark canvas against which the index markers and Arabic numerals read with clarity and confidence. This interplay of luminous stones, warm gold, and deep black creates a visual hierarchy that rewards close inspection.

Power comes from Hublot's in-house automatic Unico calibre, a skeletonised flyback chronograph movement visible through the exhibition caseback. The Unico movement is manufactured entirely by Hublot and has earned wide respect for its column-wheel construction, lateral clutch, and flyback function—all executed in a relatively slim package for a chronograph of this complexity. Paired with the black rubber strap, the watch retains Hublot's sporty DNA even in this precious-metal form, and the rubber's tactile grip ensures comfortable, secure wearing from day into evening.
