BRILLIANT DIAMOND PAVÉ FIRE ON SOLID 18K KING GOLD ARCHITECTURE

Projecting profound luxury and an authoritative presence, this watch features a bold 44mm multi-layered 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 technical profile elevates its opulence into the realm of high jewelry, featuring a case paved with 162 brilliant-cut diamonds totaling ~1.1 carats and paired with a bezel set with an additional 126 diamonds totaling ~1.4 carats. Secured by 6 signature H-shaped titanium screws, this spectacular diamond armor delivers a commanding stance on the wrist along with a robust 100m water resistance.

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 sharp, architectural, and avant-garde aesthetic, contrasting beautifully with the fire of the surrounding diamonds. 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, it is fitted with a black structured lined rubber strap, ensuring premier ergonomics and absolute confidence.
