CRYSTALLINE MAJESTY IN WATER BLUE SYNTHETIC SAPPHIRE

Evoking the striking appearance of a pure block of oceanic ice sculpted to perfection, this watch projects profound luxury through its 44mm case forged from Polished Water Blue Sapphire Crystal. This creation represents the perfect synergy between Hublot’s master chemists and engineers who successfully mastered synthetic sapphire—a material almost entirely scratch-proof (second only to diamond) and incredibly challenging to machine. The uniform execution of both the polished case and matching bezel captures and refracts light flawlessly, transforming the entire timekeeper into a mesmerizing work of art that delivers an elite and confident statement on the wrist.

POLISHED TRANSPARENT SKELETON DIAL – THE OPEN-HEART EXPERIENCE

The soul of this masterpiece resides in its stunning polished transparent skeleton dial, which completely removes traditional boundaries to celebrate pure mechanical expression. The openwork design exposes the complex microscopic components and gears spinning in an unfiltered horological display. The bold hands and hour markers are sharply finished, ensuring excellent legibility under the anti-reflective sapphire crystal. To achieve absolute aesthetic continuity, the timepiece is beautifully paired with transparent water blue lined rubber straps, completing a fluid and avant-garde design language.

MANUFACTURE CALIBRE HUB1280 UNICO – THE PULSE OF ABSOLUTE PRECISION

Ensuring the enduring and reliable performance of this crystal creation is the in-house self-winding HUB1280 Unico movement. Engineered with a simplified architecture of 354 components to maximize robustness, this premier automatic integrated flyback chronograph proudly exposes its double clutch system and iconic column wheel from the dial side. The mechanical heart maintains a steady, powerful pulse and delivers a robust 72-hour power reserve. Backed by Hublot’s elite 5+5 extended warranty for 10 full years of international assurance, this sapphire masterpiece represents an invaluable symbol of fearless innovation and the highest echelons of luxurious living.
