About Hublot King Gold Watches
Hublot introduced King Gold as a proprietary alloy that blends gold with platinum-group metals to achieve a richer, deeper rose tone and significantly improved surface hardness compared to traditional 18-karat rose gold — a meaningful advancement for a brand whose philosophy centers on the Art of Fusion. The Sang Bleu collaboration, which produced references across both the classic Big Bang case and the tonneau-shaped Spirit of Big Bang, is among the most visually distinctive partnerships in modern watchmaking, fusing Büchi's bold geometric lattice work with Hublot's technical case architecture. References span the 39mm Big Bang format up to the 45mm Sang Bleu II generation, with the Spirit of Big Bang delivering that same DNA in a barrel-shaped case that emphasizes the angular, tattoo-inspired dial motifs even further. High Jewellery variants elevate the concept further still, incorporating intensive pavé stone-setting across the case, dial, and bezel.
What to Look For
When comparing references within this King Gold Sang Bleu collection, pay close attention to case shape — the Spirit of Big Bang (6xx-series references) uses the elongated tonneau form while the Big Bang (4xx-series) uses the round case — and to the pavé configuration, as listings specify white pavé, blue pavé, and full pavé dials that meaningfully affect both aesthetics and market value. Case size is equally important: 39mm pieces such as reference 465.OS.1118.VR.1704.MXM20 wear considerably differently from the 45mm Sang Bleu II examples, and collector demand and price premiums vary accordingly. High Jewellery designations, as seen on reference 648.OX.9010.RX.9904.MXM24, indicate a far more intensive stone-setting treatment and are produced in far smaller numbers, making them the most exclusive tier in this grouping.
Frequently Asked Questions
What is Hublot King Gold and why does it matter?
King Gold is an 18-karat rose gold alloy proprietary to Hublot, formulated to be harder and more scratch-resistant than standard rose gold while delivering a distinctively warm, deep rose hue. It is used exclusively on Hublot's premium references and is a key marker that distinguishes top-tier models from those cased in stainless steel or titanium.
What is the Hublot Sang Bleu collaboration?
The Sang Bleu partnership is a creative collaboration between Hublot and Maxime Büchi, founder of the Sang Bleu tattoo studio, whose geometric and hexagonal design language is translated directly into the dials, cases, and bezels of the watches. The collection has been produced across multiple generations — Sang Bleu I and Sang Bleu II — in both the classic round Big Bang case and the tonneau-shaped Spirit of Big Bang.
