The Hublot Big Bang Unico Titanium Pavé 421.NX.1170.RX.1704 is one of the most commanding expressions in Hublot's flagship Big Bang collection, a line that has defined the brand's identity since its debut in 2005. Built around the concept of fusion — uniting unexpected materials, bold proportions, and fine watchmaking — the Big Bang rapidly became a cultural icon worn by athletes, artists, and collectors who demand a timepiece that refuses to go unnoticed.

At 44mm in diameter, the case is crafted from lightweight yet exceptionally durable titanium, a material that sits comfortably on the wrist despite the watch's architectural scale. The bezel is set throughout with brilliant-cut diamonds, adding a layer of haute joaillerie refinement to what is fundamentally a sport-derived case architecture. Six H-shaped titanium screws on the bezel — a signature Big Bang detail — anchor the design's industrial aesthetic while framing the gem-set brilliance of the surround.

The white dial of reference 421.NX.1170.RX.1704 is adorned with index hour markers complemented by Arabic numerals, maintaining excellent legibility while the diamond accents elevate the overall presentation. The Unico designation is significant: it confirms this is not merely a Big Bang but specifically a Big Bang Unico, housing Hublot's manufacture flyback column-wheel chronograph movement developed entirely in-house at the La Chaux-de-Fonds manufacture. The movement is visible through a transparent case back, rewarding the wearer with a view of the skeletonized rotor and the architecture of the calibre.

The integrated black rubber strap is produced from natural rubber — another Hublot fusion signature — and connects seamlessly to the case via the brand's proprietary One Click attachment system, allowing straps to be swapped without tools. This technical thoughtfulness means the watch transitions effortlessly from a casual daytime setting to an elevated evening context, particularly given the diamond bezel and white dial combination that reads as unmistakably luxurious.

Our team of dedicated specialists is available to answer any questions, assist with secure shipping across the United States, and ensure that your investment in this exceptional Hublot Big Bang Unico is as seamless as the watch is striking.
