About Hublot Big Bang Unico King Gold
Hublot introduced King Gold as a proprietary alloy developed to address one of the most common criticisms of traditional rose gold: its susceptibility to surface scratching. By altering the metallurgical composition, Hublot produced a gold that retains the warm, rich tone collectors expect while delivering meaningfully greater hardness. The Big Bang Unico, which houses the brand's manufacture UNICO flyback chronograph caliber, became the natural showcase for King Gold, combining the alloy's visual warmth with the movement's skeletonized architecture visible through the dial and caseback. References in this collection span clean pave settings, full white diamond configurations, and the visually dramatic Rainbow treatments where a cascade of multicolored gems lines the bezel and dial.
What to Look For
Buyers choosing between King Gold references should pay close attention to case size — the 42mm refs such as the 441-prefix models wear more versatilely on a range of wrist sizes, while the 44mm 421-prefix models offer a bolder, more statement-oriented presence. Gem configuration drives significant value differences, with Rainbow references like 421.OX.1118.LR.0999 and 441.OX.1118.LR.0999 commanding strong premiums due to the labor-intensive individual color grading and setting of each stone. Pave and white diamond variants offer a more classic high-jewelry aesthetic and remain among the most consistently sought Hublot references on the secondary market.

The Big Bang Unico line is powered by Hublot's in-house UNICO caliber, a manufacture flyback chronograph movement developed and produced entirely by Hublot.
