About the Hublot Classic Fusion Aerofusion
The Classic Fusion Aerofusion was developed by Hublot as a natural evolution of the Classic Fusion case architecture, retaining the trademark porthole-inspired bezel and multi-material construction while adding meaningful horological complications. The Moonphase variant is the defining piece of the Aerofusion line, presenting a precisely executed lunar display that complements the open, architectural quality of the movement visible through the dial. Cases are offered in grade-1 titanium, prized for its lightness and scratch resistance, and in Hublot's proprietary King Gold, an 18-karat rose gold alloy developed in-house for enhanced hardness and a richer color. The 42mm references, designated by the 547 prefix, and the larger 45mm references, designated by the 517 prefix, share the same design language while catering to different wrist sizes and wearing preferences.
What to Look For
Buyers should focus on three key variables when shopping this collection: case material, case size, and dial configuration, as each combination carries a distinct reference number and price point. Titanium models with no diamond setting, such as the 547.NX.0170.LR and 517.NX.0170.LR, represent the entry point of the line, while pavé and diamond-set variants on either King Gold or titanium cases command a premium due to the stone count and added finishing labor. Skeleton sapphire dials, found on select 45mm references, expose more of the movement architecture and are among the most collectible configurations in the Aerofusion family.
Frequently Asked Questions
What is the difference between the 42mm and 45mm Hublot Classic Fusion Aerofusion Moonphase?
The 42mm models carry reference prefixes beginning with 547, while the 45mm models begin with 517, and both sizes share the same case materials, dial options, and moonphase complication. The 45mm versions are more commonly found with skeleton sapphire dials, making them the preferred choice for buyers who want maximum visual exposure of the movement, while the 42mm offers a more versatile, slightly more understated wearing experience.
What is Hublot King Gold and how does it differ from standard gold?
King Gold is Hublot's proprietary 18-karat rose gold alloy, developed in-house with a specific composition designed to improve hardness and surface durability compared to conventional 18-karat rose gold. The result is a warmer, deeper rose tone that resists scratching better than standard gold, which is why Hublot uses it across its premium references including the Aerofusion Moonphase King Gold models like the 547.OX.0180.LR.1704.
