The Hublot Big Bang Unico 411.CM.1138.RX is one of the most compelling expressions of the Big Bang line, pairing an openworked skeleton Arabic dial with a 45mm black ceramic case and a statement fixed yellow gold bezel. Launched as part of Hublot's Art of Fusion philosophy, the Big Bang family has been the brand's flagship since its introduction in 2005, and the Unico variant elevates that legacy by housing an in-house automatic flyback chronograph movement visible through the skeletonized dial and exhibition caseback.

The 45mm black ceramic case is a defining feature of this reference. Hublot employs a proprietary microblasted ceramic that is exceptionally resistant to scratches, corrosion, and everyday wear while remaining lightweight on the wrist. The bold diameter and tonneau-influenced lug architecture give the watch a commanding wrist presence that has come to define the modern luxury sports watch category.

The fixed yellow gold bezel frames the dial with a warm, precious-metal contrast that immediately draws the eye. Hublot's signature six H-shaped titanium screws ring the bezel, a design detail that has become instantly recognizable and speaks to the brand's industrial-chic DNA. Against the deep black ceramic, the yellow gold pops with a richness that feels simultaneously sporty and haute horology.

At the heart of the watch is an automatic Unico in-house caliber, developed and manufactured entirely by Hublot. The skeletonized Arabic dial reveals the movement's architecture in dramatic fashion, with Arabic numeral hour markers applied over the open work to ensure legibility while celebrating the mechanical complexity beneath. This marriage of form and function is what separates the Big Bang Unico from conventionally finished competitors.

The black rubber strap — a hallmark of the Big Bang line since its debut — provides comfort and flexibility for daily wear, and its matte finish plays off the ceramic case to keep the overall look cohesive and purposeful. Whether worn at a boardroom presentation or a weekend event, the 411.CM.1138.RX commands attention without sacrificing wearability.

Bizak & Co. offers this Hublot Big Bang Unico 411.CM.1138.RX brand new, complete with box and papers, at the best available price. Our team of luxury watch specialists is ready to answer every question, provide detailed photographs, and facilitate a seamless purchase experience.
