Spirit OF Big Bang King Gold Rainbow 42MM

REGAL 18K KING GOLD FRAMEWORK COATED IN A MESMERIZING NATURAL GEMSTONE MATRIX

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, this luxury profile undergoes a breathtaking transformation via a high-jewelry gem-setting technique. The case body is embedded with 156 hand-selected vibrant gemstones, creating a seamless gradient profile featuring Rubies, Pink Sapphires, Amethysts, Blue Sapphires, Blue Topazes, Tsavorites, and Yellow and Orange Sapphires.

The glittering gemstone tapestry extends onto an opulent polished King Gold bezel, set with 54 baguette-cut colored gemstones aligned in a perfect chronological rainbow sequence. Punctuated and secured firmly by 6 iconic H-shaped titanium screws, the highly robust housing is paired with an integrated black rubber strap backed by multicolored rainbow alligator leather and secured by an 18K King Gold and black-plated stainless steel deployment clasp. Backed by a robust 100m water resistance (10 ATM), its structural integrity remains entirely uncompromised.

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 feature matching color-coded gem accents and stand out in sharp relief against the intricate gear train below, generously treated with premium luminescent material to guarantee 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.
