BRILLIANT DIAMOND FIRE ON SOLID 18K KING GOLD ARCHITECTURE

Projecting profound luxury and an authoritative presence, this watch features a bold 44mm chassis meticulously sculpted from solid 18-carat King Gold. Developed entirely by Hublot’s master alchemists, this proprietary alloy offers a significantly warmer and richer shade than traditional red gold, achieving long-term color stabilization through a precious addition of platinum. The intricate execution showcases a flawless interplay between satin-brushed surfaces and mirror-polished hand-finished bevels, bringing exceptional contrast to the multi-layered case silhouette. The technical profile elevates its opulence by surrounding the openwork engine with a bezel set with 126 brilliant-cut diamonds totaling ~1.4 carats, secured by 6 signature H-shaped titanium screws. Paired with a robust 100m water resistance, this heavy gold armor delivers a commanding stance on the wrist.

MATTE BLACK SKELETON DIAL – THE OPEN-HEART MECHANICAL THEATRE

The soul of this masterpiece resides in its stunning matte black skeleton dial, which introduces a highly technical, sharp, and avant-garde aesthetic. By eliminating conventional barriers, the openwork architecture invites the wearer to observe a dynamic mechanical theatre, revealing the rotating date disc, intricate wheel trains, and the flawless alignment of the Unico movement layout spinning under the anti-reflective sapphire crystal. The applied indices and hands, forged from matching King Gold tones and treated with premium luminescence, stand out brilliantly against the dark canvas for absolute legibility. To complete this high-end sport look, the timepiece is paired with a black structured lined rubber strap, delivering premier ergonomics and absolute confidence.
