Description
BBF Edition Hublot Big Bang Unico Yellow Magic 42mm 441.CY.471Y.RX
A precise horological replication featuring a fully functional dial-side column wheel and accurate ceramic pigment saturation.
Powered by Custom HUB1280 Unico
The transition from off-the-shelf bases to the custom HUB1280 Unico clone marks a critical evolution for this reference. By engineering a bespoke architecture, BBF successfully relocated the chronograph column wheel to the 6 o’clock position on the dial side, ensuring it actuates visibly when the pushers are engaged. This integrated approach not only mirrors the mechanical layout of the genuine caliber but also allows the case to maintain a more accurate 15.4mm thickness.
Properly regulated, this custom HUB1280 Unico clone operates within a tolerance of ±8–12 seconds per day, delivering reliable chronometric performance for a complex flyback module.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Working Flyback Chronograph, Date
- ✅ Winding Direction: Unidirectional
Technical Specifications
Measuring a verified 42mm in diameter and 15.4mm thick, the case weighs exactly 128.9g. The high-tech ceramic is sintered to achieve a highly scratch-resistant, vibrant finish.
The open-worked layout provides a clear view of the HUB1280 mechanics. It features crisp yellow Arabic numerals and hands treated with luminescent material for optimal contrast.
Secured by the signature H-shaped titanium screws, the bezel matches the case pigment precisely, exhibiting the correct polished sheen and tone accuracy versus the genuine article.
Constructed from structured lined rubber, the strap integrates seamlessly with the case and utilizes a smooth-actuating deployant clasp for secure wear.
Why BBF for This Reference?
Many collectors ask: “Why not V6F?”
While V6F previously produced notable Hublot replicas, their Unico models relied heavily on modified Asian 7750 movements. This resulted in a noticeably thicker case profile and a decorative, non-functional column wheel on the dial. The BBF edition solves this by utilizing the custom HUB1280, yielding the verified 15.4mm thickness and genuine mechanical interaction visible at 6 o’clock.
Full Disclosure: Due to the skeletonized case architecture and the clone movement’s gear train, rotor winding noise is slightly more pronounced than on the genuine Hublot caliber.

Collector Q&A
Q: Does the flyback function operate exactly like the genuine HUB1280?
A: Yes, the BBF custom clone allows the chronograph to be reset without stopping first, mirroring the genuine Unico flyback mechanics.
Q: How does the yellow ceramic color compare to the authentic ‘Yellow Magic’?
A: BBF has achieved a highly accurate saturation level for the yellow pigment, avoiding the pale or burnt tones seen in earlier ceramic replica attempts, though under direct UV light, a marginal variance in reflectivity is present.
Q: Is the column wheel at 6 o’clock functional or decorative?
A: Unlike older 7750-based versions where it was a faux plate, the BBF HUB1280 features a fully functional column wheel visible on the dial side that actuates when the chronograph pushers are engaged.
Q: Is the rotor noisy on this specific BBF Unico movement?
A: Yes, due to the skeletonized case architecture and the clone movement’s gear train, rotor winding noise is more audible compared to the genuine caliber. A light application of Moebius 9010 oil by a watchsmith can mitigate this.
