Hublot Big Bang Unico Chronograph Black Magic Ceramic 42mm 441.CI.1170.RX

The Hublot Big Bang Unico Chronograph Black Magic — reference 441.CI.1170.RX — is one of the most visually commanding expressions of a model line that redefined what a luxury sport watch could look like when Hublot introduced the Big Bang family in 2005. Built around the philosophy of fusion — blending unexpected materials, avant-garde design, and serious horological craft — the Big Bang quickly became the anchor of Hublot's identity and remains among the most recognizable luxury chronographs in the world today.

At 42mm, this reference occupies the sweet spot of the Big Bang family: large enough to command attention on the wrist without crossing into oversized territory. The case, middle, and bezel are all rendered in black ceramic — a high-tech material prized for its extreme hardness, near-total scratch resistance, and featherweight feel compared to steel. Ceramic's deep, uniform matte-black finish is virtually immune to the micro-scratches that accumulate on metal cases over time, meaning the watch retains its factory appearance through years of wear.

The skeleton dial is the defining feature of the Unico variant, offering an open-worked architecture that transforms the dial into a window onto the movement. Index and Arabic numeral hour markers are integrated into the chapter ring, providing legibility without cluttering the view of the intricate mechanics beneath. The result is a dial that rewards close inspection while remaining immediately readable at a glance — a balance that is genuinely difficult to achieve in skeleton watchmaking.

Powering the 441.CI.1170.RX is Hublot's proprietary automatic chronograph movement, the UNICO caliber — developed entirely in-house and visible through the open dial and exhibition caseback. The UNICO is a column-wheel, flyback-capable chronograph movement and represents a significant investment by Hublot in vertical integration. Its presence in this reference signals genuine manufacture credibility, placing the Big Bang Unico in a different conversation from watches that rely on ebauche chronograph movements.

The black rubber strap is purpose-built for this case, connecting via Hublot's signature one-click interchangeable strap system that allows rapid strap changes without tools — a practical luxury feature that broadens the watch's versatility. Paired with the all-black ceramic hardware, the strap reinforces the watch's sport-luxury DNA and ensures comfortable, secure wear whether at the racetrack, a boardroom, or a weekend getaway.
