Hublot 642-CI-0170-RX Big Bang 42 mm Watch

The Art of Fusion: Where King Gold Meets High-Tech Ceramic

Hublot has built its legacy on a single, powerful concept: “The Art of Fusion.” The Hublot Big Bang 642.CI.0170.RX is the epitome of this philosophy, representing a perfect union between precious metals and cutting-edge industrial materials. This 42mm timepiece is not merely a watch; it is a statement of bold sophistication, designed for those who appreciate the juxtaposition of warmth and resilience.

A Masterclass in Contrast: Design and Craftsmanship

At first glance, the 642.CI.0170.RX commands attention with its striking visual tension. The case is crafted from Hublot’s exclusive 18K King Gold—a proprietary alloy richer in copper than traditional 5N gold, resulting in a deeper, warmer, and more intense red-gold hue that resists fading over time. This opulent material is masterfully contrasted with a sleek, satin-finished black ceramic bezel. The bezel’s iconic “H” screws, rendered in titanium, add an industrial edge to the luxurious composition.

The exhibition caseback, secured by six titanium screws, offers a glimpse into the heart of the machine, protected by scratch-resistant sapphire crystal.

Engineered for Performance: The Movement and Functionality

Beneath the surface lies the Hublot Calibre HUB4100, a self-winding mechanical chronograph movement. This powerhouse is not just about precision; it’s about endurance. With a robust 42-hour power reserve, the watch ensures reliable performance whether you’re in the boardroom or at a gala. The chronograph functions are intuitively managed via the screw-down pushers, while the black composite resin bezel with tachymeter scale allows for precise speed measurement, adding a layer of sporty utility to its luxurious facade.

The open-worked dial, protected by an anti-reflective sapphire crystal, reveals the intricate skeletonized architecture, featuring rhodium-plated indices and striking black-coated hands. The black rubber strap, true to Hublot’s signature, features the “Easy-Exchange” system, allowing you to swap it effortlessly without tools.
