This Big Bang Unico 441.NX.1171.RX pairs a 42mm Grade 5 titanium case with a matching titanium bezel and a black structured rubber strap. Its skeletonized chronograph display is driven by a custom HUB1280 clone caliber with the column wheel positioned on the dial side, an exposed date wheel, and approximately 36 hours of power reserve.
42mm Grade 5 Titanium Build
The Hublot Big Bang Unico 441.NX.1171.RX is built around a 42mm Grade 5 titanium case with a stated thickness of 15.5mm. This configuration gives the watch a distinctly technical profile while keeping the focus on the material and architecture that define this reference. The listed weight is 125.4 grams, and the case construction is presented here with the same metal specified for the bezel, creating a consistent titanium exterior across the watch.
The bezel is also Grade 5 titanium and finished with alternating brushed and polished surfaces. That contrast works directly with the case design and reinforces the multi-part construction of the Big Bang Unico platform. For buyers looking at this reference specifically, the titanium execution is one of the clearest differentiators in the watch’s overall presentation.
Industrial Grey Skeleton Dial with Chronograph Layout
The dial is described as an industrial grey skeleton display with matte black accents. Its open-worked layout puts the movement architecture at the center of the watch, rather than hiding it behind a solid dial. The visible mechanics are a major part of this model’s character, especially with the chronograph system arranged to show more of the operating structure from the front.
This watch also features an exposed date wheel, with the date integrated into the skeletonized display rather than separated into a conventional solid-window layout. The chronograph is fully functional, and the visible column wheel is positioned on the dial side. That placement is a defining detail of the watch because it changes what you see from the front and gives the skeletonized format a more technical, mechanically driven look.
Custom HUB1280 Clone Movement
Powering the watch is a custom HUB1280 clone caliber. This movement is specifically noted for moving away from older 7750-based modified layouts and instead using an architecture designed around the Unico-style display. The dial-side column wheel is part of that layout, and it is one of the most important details for anyone choosing this reference over a more generic chronograph configuration.
The power reserve is approximately 36 hours. Along with the functional chronograph, the watch also includes the exposed skeleton date wheel as part of its complication set. The movement’s presentation is inseparable from the watch’s design, since the skeleton dial is built to showcase the gear train, chronograph mechanism, and date display from the front.
Structured Rubber Strap and One-Click System
The watch is fitted on a black structured rubber strap with a titanium deployant clasp. This strap choice matches the modern, technical direction of the case and dial while keeping the overall configuration true to the specification of this reference. The textured rubber profile is a defining part of the look and gives the titanium case a direct, sporty pairing.
It also includes the One-Click quick-release system, allowing the strap to be released through the integrated lug mechanism. That feature is explicitly part of this watch’s setup and adds a practical element to the overall construction without changing the clean integration between case and strap.
Sapphire Crystal and Titanium Bezel Details
Over the dial, the watch uses a sapphire crystal with double AR coating. This keeps the attention on the skeletonized display and supports the open, mechanical front view that defines the Unico layout. Combined with the titanium bezel and the grey-and-black dial treatment, the crystal choice completes a specification focused on visible movement architecture and contemporary materials.
For a buyer choosing this exact 441.NX.1171.RX configuration, the appeal is in the combination of a 42mm Grade 5 titanium case, industrial grey skeleton dial, custom HUB1280 clone movement, and black structured rubber strap. Every major element of the watch is tied directly to that technical Unico identity.
