Description
BBF Hublot Big Bang Unico King Gold Pavé 42mm
BBF establishes the benchmark for the 42mm Unico platform by engineering a true HUB1280 clone with correct dial-side architecture.
Powered by Custom HUB1280 Clone
The BBF custom HUB1280 represents a major horological step forward for Hublot replicas. Unlike previous iterations relying on heavily modified Asian 7750 base movements, this caliber features a visible, functional column wheel on the dial side and a horizontal clutch at 8 o’clock. The flyback mechanism operates smoothly, allowing instantaneous resetting of the chronograph without stopping.
Regulated to approximately ±10–15 seconds per day. The complex chronograph module requires stable power delivery to maintain amplitude when engaged.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: 60-Minute Flyback Chronograph, Skeletonized Date
- ✅ Winding Direction: Unidirectional
Technical Specifications
The case measures 42mm in diameter and a verified 15.4mm in thickness, weighing exactly 180g. The King Gold plating exhibits the correct intense red hue.
Features the correct rainbow texture hands and a sharp dial accent tone. The skeletonized date wheel sits perfectly flush at 3 o’clock.
Fully encrusted with precision-set stones and secured by the signature H-shaped titanium screws. The alignment and setting depth are highly consistent.
Equipped with a functional quick-change system. The deployant clasp is color-matched with King Gold plating and engages with minimal endplay.
Why BBF for This Reference?
Many collectors ask: “Why not ZF?”
While ZF produces excellent standard Big Bang models, BBF’s investment in the custom HUB1280 movement yields superior dial-side architecture for the Unico series. The functional column wheel and true 60-minute counter provide mechanical accuracy that standard modified chronographs cannot match.
Full Disclosure: The synthetic crystals used in the pavé setting lack the exact refractive index of genuine Hublot VVS diamonds under direct sunlight.

Collector Q&A
Q: Does the flyback chronograph function like the genuine HUB1280?
A: Yes, the BBF custom caliber replicates the flyback mechanism, allowing you to reset and restart the chronograph with a single pusher press. It also features the correct 60-minute counter at 3 o’clock, rather than the 30-minute counter found on standard 7750 clones.
Q: Are the stones on the case and bezel real diamonds?
A: No, the pavé setting utilizes high-grade synthetic crystals. While they provide excellent brilliance and are set with precision, they do not possess the exact refractive index of genuine Hublot VVS diamonds.
Q: Does the quick-change strap system work with genuine Hublot straps?
A: Yes, the BBF ‘One Click’ quick-change system is engineered to genuine tolerances, allowing seamless swapping with OEM Hublot 42mm Unico straps.
Q: What is the primary technical limitation of this BBF replica?
A: The rotor mechanism on this clone caliber can be audibly louder than the genuine HUB1280. Additionally, the 18K King Gold plating, while thick, requires mindful wear to avoid exposing the steel base layer through deep scratches.
