Hublot Big Bang Unico Black Magic 421.CI.1170.RX Skeleton Dial

The Hublot Big Bang Unico Black Magic is a bold expression of the brand’s signature fusion philosophy, combining cutting-edge materials with an unmistakably modern design. This example, reference 421.CI.1170.RX, features the commanding 44mm case, offering strong wrist presence and a distinctly technical aesthetic.

The case is crafted entirely from black ceramic, a material prized for its lightweight feel, scratch resistance, and deep matte finish. The watch showcases a dramatic skeleton dial, revealing the architecture of the chronograph movement and emphasizing the mechanical character that defines the Big Bang Unico collection. A scratch-resistant sapphire crystal protects the dial while maintaining maximum transparency.

At its core is Hublot’s in-house Unico automatic chronograph movement, featuring a modern column-wheel construction and flyback chronograph functionality. Designed for performance and reliability, the movement reinforces the watch’s sporty credentials while delivering true horological substance. The watch is paired with a comfortable and durable black rubber strap, perfectly complementing the all-black “Black Magic” aesthetic.
