Description
BBF Factory Hublot Big Bang Unico King Gold Jewellery 42mm
BBF establishes the definitive standard for the skeletonized Unico platform by integrating a structurally accurate HUB1280 clone within a precisely weighted 182.1g gem-set chassis.
Powered by Clone HUB 1280
The engineering core of this replica is the BBF Clone HUB 1280 automatic movement, a significant departure from older iterations that relied on decorative plates over a standard 7750 base. This caliber features a visible, active column wheel at the 6 o’clock position and a fully skeletonized date disc, matching the visual depth of the genuine movement. The chronograph mechanism engages with crisp tactile feedback, driven by a gear train architecture that closely mimics the original Hublot design.
Regulated to approximately ±10–15 seconds per day, which represents standard operational tolerance for complex clone chronograph calibers of this architectural density.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Fully functional chronograph, skeletonized date display, active dial-side column wheel
- ✅ Winding Direction: Bidirectional rotor winding
Technical Specifications
Measuring exactly 16mm in thickness and weighing 182.1g, the multi-component case construction accurately replicates the sandwich design of the genuine Unico line.
Exhibits sharp edge finishing on the exposed bridges. While our database flags a dark green annotation, the physical dial correctly presents the rose gold and black contrast of the 441.OX.1181.RX.0904.
Features meticulously aligned synthetic stones secured within precise channel settings, fastened by Hublot’s signature H-shaped titanium screws.
Integrated rubber strap utilizing the proprietary One Click quick-release system, finished with a heavy-duty King Gold plated deployant buckle.
Why BBF for This Reference?
Many collectors ask: “Why not HB Factory?”
While HB produces competent Big Bang replicas, BBF holds a distinct advantage in the Unico series due to their proprietary HUB1280 clone movement. The visual accuracy of the dial-side column wheel and the precise 16mm case thickness give the BBF version superior structural fidelity compared to alternatives using thicker, modified 7750 calibers.
Full Disclosure: The automatic winding rotor exhibits slightly more audible bearing noise than the genuine Hublot caliber, a common trait in clone chronographs. Furthermore, the King Gold plating requires careful wear to prevent exposing the steel base metal.

Collector Q&A
Q: Does the chronograph function exactly like the genuine HUB1280?
A: Yes, the BBF clone HUB1280 features a fully functional chronograph with an active column wheel visible at the 6 o’clock position, mirroring the genuine architecture rather than using decorative plates.
Q: How accurate is the gem-setting on the bezel compared to the genuine 441.OX.1181.RX.0904?
A: BBF utilizes high-grade synthetic stones with precise channel setting. While it successfully captures the luxurious aesthetic at wrist distance, under macro inspection, the clarity and light refraction will differ from genuine factory diamonds.
Q: Will the King Gold plating fade or tarnish over time?
A: Like all plated replicas, the King Gold finish is durable for daily wear but susceptible to deep scratches that can reveal the steel base. It requires more careful handling compared to solid ceramic or bare titanium models.
Q: What is the most notable flaw on this BBF Unico reference?
A: The automatic winding rotor exhibits slightly more audible bearing noise than the genuine Hublot caliber, and the power reserve is practically limited to approximately 36 hours rather than the 72 hours found in the genuine piece.
