REGAL 18K KING GOLD CHASSIS AND THE RESILIENT DEFENSE OF A BLUE CERAMIC PERIMETER

This exceptional timepiece projects absolute dominance through its signature 42mm barrel-shaped (Tonneau) multi-layered sandwich case, beautifully sculpted from Hublot’s exclusive 18K King Gold alloy. Developed with platinum to achieve a significantly warmer and richer tone than traditional 5N gold, the King Gold structure features a beautiful alternating interplay of satin-brushed surfaces and highly polished beveled facets. The robust silhouette is brilliantly contrasted by a high-tech blue ceramic bezel. Sintered from zirconium dioxide at extremely high temperatures, this advanced ceramic material is finished using custom microblasting and edge-polishing, adding a rich architectural contrast in royal blue while ensuring absolute resiliency against the hazards of daily life. Fitted with an integrated black and blue structured lined rubber strap and a premium 18K King Gold and black-plated titanium deployment clasp, the high-concept structure guarantees an impressive and robust 100m water resistance (10 ATM).

TRANSPARENT SAPPHIRE INTERFACE AND THE ANTHOLOGY OF HIGH-FREQUENCY GOLD MECHANICS

The visual soul of this creation is beautifully laid bare through its minimalist transparent sapphire crystal dial. This highly technical skeletonized interface is meticulously engineered to keep the comprehensive chronograph readings perfectly clean and highly scannable, displaying sub-dials for chronograph tracking, a continuous running seconds counter, and a discrete date window at 4:30 driven by an exposed calendar wheel. The applied King Gold indices and bold baton hands stand out in sharp relief against the intricate gear train below, generously treated with premium luminescent material to guarantee absolute legibility under any lighting condition.

MANUFACTURE CALIBRE HUB4700: MECHANICAL DOMINANCE WITH INTEGRATED SILICON TECHNOLOGY

Ensuring absolute reliability and precision is the mechanical self-winding Calibre HUB4700 skeleton chronograph movement, the proud successor to the legendary El Primero caliber of 1969. As the first integrated automatic chronograph movement to operate at a blazing frequency of 5Hz (36,000 alternations per hour), this engine allows an official timing accuracy down to 1/10th of a second. In a perfect fusion of heritage and watchmaking innovation, this entirely open-worked caliber is enhanced with high-tech silicon regulating components, unlocking anti-magnetic avant-garde performance and unparalleled rate stability. Maintaining a reliable 50-hour power reserve, this self-winding mechanism stands as a legendary hallmark of modern luxury, curated strictly for the global elite collector.
