Description
BBF Factory Hublot Big Bang Unico Red Magic 42mm 441.CF.8513.RX
A breakthrough in ceramic coloring technology paired with a deeply engineered skeletonized chronograph caliber.
Powered by Custom HUB1280 Clone
The movement inside this release represents a significant engineering shift for Hublot replicas. Rather than masking a standard Valjoux 7750 base with decorative plates, BBF developed a custom architecture that accurately mimics the HUB1280’s dial-side mechanics. The skeletonized date wheel and active column wheel function as intended during chronograph operation, providing a visually dynamic experience.
The rated accuracy for this custom clone movement is typically ±10–15 s/day depending on resting position and winding habits.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Fully functional chronograph, skeletonized date mechanism
- ✅ Winding Direction: Unidirectional
Technical Specifications
The 42mm case exhibits excellent scratch resistance and a polished finish that refuses to fade. The sintering process achieves the dense structural integrity required for the Big Bang profile.
Floating Arabic numerals and indices sit above the exposed movement. The depth of the skeletonization is highly accurate, providing clear visibility of the underlying gear train.
Secured via 6 polished titanium H-screws. The contrast between the vivid red ceramic and the metallic screws is sharp, with precise machining on the screw heads.
Integrated red rubber strap featuring a titanium deployant clasp. The quick-release ‘One Click’ system operates smoothly with minimal endplay tolerance.
Why BBF for This Reference?
Many collectors ask: “Why not ZF?”
BBF’s primary advantage lies in its ceramic pigmentation. Achieving the specific ‘Ferrari-red’ saturation is notoriously difficult, often resulting in muddy or excessively dark burgundy tones from other factories. BBF’s sintering process yields the correct bright hue, while their custom HUB1280 clone maintains a more accurate overall case thickness compared to 7750-based alternatives.
Full Disclosure: The rotor bearing on this custom clone exhibits slightly more auditory feedback than the genuine movement during vigorous wrist rotation.

Collector Q&A
Q: Does the chronograph function exactly like the genuine HUB1280?
A: Yes, the BBF custom clone features a fully functional chronograph with a working column wheel visible from the dial side, unlike older versions that used decorative plates over standard movements.
Q: How accurate is the ‘Magic Red’ ceramic color compared to retail?
A: BBF achieves a highly accurate ‘Ferrari-red’ saturation through an advanced sintering process. This avoids the darker, burgundy tint often seen in lower-tier replicas of the 441.CF.8513.RX.
Q: Does the ‘One Click’ quick-release strap system work on this BBF model?
A: Yes, the proprietary strap release mechanism is fully functional, allowing you to swap compatible Hublot straps without the need for specialized tools.
Q: What is the main drawback of this BBF replica?
A: The primary limitation is the rotor noise; the custom HUB1280 clone has a slightly louder bearing than the genuine movement during vigorous motion. Additionally, while highly scratch-resistant, the ceramic case can be brittle and may chip upon severe hard impacts.
