About Hublot King Gold Watches
King Gold is a patented alloy created by Hublot that blends 18-karat gold with a proprietary mix of elements designed to produce a distinctive reddish-amber hue that sets it apart from standard rose or red gold offerings in the luxury watch market. The Classic Fusion Aerofusion Moonphase line sits at the intersection of high horology and avant-garde design, featuring a see-through moonphase display executed on an open-worked dial that showcases the movement architecture beneath. The combination of King Gold cases with skeletonized sapphire dials and flying tourbillon-adjacent aesthetics makes these references among the most visually complex and collectible pieces in the Classic Fusion family. Both the 42mm models, preferred by wearers seeking a slightly more understated profile, and the larger 45mm references appeal to collectors who prize bold wrist presence alongside genuine watchmaking craft.
What to Look For
When shopping Hublot Classic Fusion Aerofusion Moonphase King Gold watches for sale, the key differentiators are case size, dial configuration, and diamond coverage: the 45mm references carry the 517 prefix while 42mm models carry the 547 prefix, and suffix codes such as .1104 or .1704 indicate the level of diamond or pavé setting on the bezel and dial. Value is further driven by condition and box-and-papers completeness, with brand-new examples commanding a premium over pre-owned pieces, while skeleton sapphire dial variants tend to attract higher collector interest than standard open-worked configurations.
Frequently Asked Questions
What is Hublot King Gold and how does it differ from regular rose gold?
King Gold is an 18-karat gold alloy proprietary to Hublot, formulated to achieve a deeper, more saturated warm tone than conventional rose gold while offering improved hardness and scratch resistance. It is exclusive to Hublot and cannot be found in other brands' collections, which contributes to its desirability among collectors.
What is the difference between the 42mm and 45mm Aerofusion Moonphase King Gold references?
The 45mm models carry the 517 reference prefix, such as 517.OX.0180.LR, while the 42mm versions use the 547 prefix, for example 547.OX.0180.LR, with both sizes sharing the same Aerofusion moonphase complication and King Gold case construction. The size choice primarily affects wrist presence and proportionality, with the 42mm often favored for a more versatile everyday wear profile.
What do the suffix codes like .1104 and .1704 mean on these Hublot references?
The suffix codes indicate the diamond or pavé setting configuration applied to the watch: references ending in .1104 feature diamond-set bezels or dials, while those ending in .1704 denote a pavé setting with a higher overall stone count and coverage. References without these suffixes, such as 517.OX.0180.LR, represent the non-diamond versions of the same model.
