Description
BBF Hublot Big Bang Unico Black Magic 42mm 441.CI.1171.RX
BBF achieves an accurate 15.4mm case profile and functional dial-side column wheel, establishing this as the current benchmark for 42mm Unico replicas.
Powered by Clone HUB1280
The clone HUB1280 caliber is a significant horological achievement within the replica market, engineered specifically to replicate the dial-side mechanics of the genuine Unico movement. By integrating the chronograph module directly into the mainplate rather than stacking it, the movement allows the case to maintain its verified 15.4mm thickness. The column wheel at 6 o’clock is fully functional, rotating cleanly with each actuation of the chronograph pushers, while the exposed date ring advances crisply at midnight.
Regulated to approximately ±10–15 seconds per day. The high-beat escapement provides a smooth sweep for the central chronograph seconds hand.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Flyback-style chronograph (standard operation), 60-minute counter, skeletonized date display
- ✅ Winding Direction: Unidirectional
Technical Specifications
The multi-part case construction measures 42mm in diameter and a verified 15.4mm thick. The micro-blasted finish provides a matte, stealth aesthetic that resists fingerprints and minor abrasions.
The open-worked dial exposes the movement architecture beneath. The matte black and dark grey accents align closely with the genuine, featuring correctly proportioned Arabic numerals filled with luminescent material.
The micro-blasted ceramic bezel is secured by six signature H-shaped titanium screws. The screws are correctly polished and sit flush within their respective countersinks.
Features the proprietary “One Click” quick-release system. The black rubber strap is supple and secures via a black-plated titanium and ceramic deployant buckle.
Why BBF for This Reference?
Many collectors ask: “Why not ZF?”
While ZF produces excellent Hublot replicas, BBF’s execution of the HUB1280 movement architecture is superior for the 42mm Unico platform. By utilizing this specific clone caliber, BBF achieves a verified case thickness of 15.4mm, avoiding the bloated 17mm+ profiles found on earlier 7750-based modifications. The integration of the functional dial-side column wheel seals its position as the premium choice for this reference.
Full Disclosure: The automatic winding rotor on the clone HUB1280 produces slightly more audible noise than the genuine movement, and the “One Click” strap release buttons exhibit marginal lateral play under tight scrutiny.

Collector Q&A
Q: Does the dial-side column wheel actually function on this BBF clone?
A: Yes, the clone HUB1280 features a fully functional column wheel visible at the 6 o’clock position on the dial. It physically engages and rotates when the chronograph pushers are activated, accurately mimicking the genuine movement architecture.
Q: Are the case dimensions identical to the genuine 441.CI.1171.RX?
A: The BBF case measures 42mm in diameter with a verified thickness of 15.4mm. This is highly accurate to the genuine article and successfully avoids the excessive thickness commonly found on older 7750-based Hublot replicas.
Q: Is the ‘One Click’ strap exchange system functional?
A: Yes, the trapezoidal buttons on the lugs fully operate the quick-release mechanism, allowing compatibility with aftermarket or genuine Hublot Unico 42mm straps. However, the release buttons may exhibit slightly more lateral play than the genuine mechanism.
Q: What is the most noticeable flaw on this BBF Unico Black Magic?
A: The automatic winding rotor on the clone HUB1280 produces a more audible spinning noise than the genuine movement. Additionally, under macro magnification, the micro-blasted ceramic finishing on the inner lug bevels is slightly less refined.
