Description
BBF Hublot Big Bang Unico Sang Bleu II 45mm All-Black Ceramic
A highly technical execution of modular ceramic case construction and geometric disc hand mechanics.
Powered by Clone HUB 1240
The Clone HUB 1240 represents a significant departure from standard off-the-shelf chronograph movements. BBF has heavily modified the base architecture to support the substantial weight of the Sang Bleu geometric disc hands without compromising the gear train. The movement features a functioning flyback mechanism, allowing the user to reset and restart the chronograph with a single press. Visually, the skeletonized bridges and custom rotor accurately mimic the UNICO layout, providing the correct depth when viewed through the sapphire crystal.
±10–15 seconds per day. Due to the high torque required to drive the geometric discs, amplitude variations are normal across different states of wind.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Flyback chronograph, 60-minute timing, hollow calendar ring
- ✅ Winding Direction: Unidirectional winding rotor
Technical Specifications
The 45mm case utilizes a 12-piece modular construction. The facets are sharply defined, alternating between satin-brushed surfaces and highly polished chamfers, secured by polished titanium H-screws.
Time is read via overlapping octagonal discs. The skeletonization reveals the date wheel and movement plates, with a deep contrast hue visible under specific lighting angles. The hollow calendar window aligns correctly at the 4:30 position.
A fixed hexagonal bezel that transitions seamlessly into the complex case geometry. The edges are crisp, avoiding the rounded ‘melted’ look found on lower-tier replicas.
Constructed from premium vulcanized rubber featuring the Sang Bleu geometric motif. The quick-release system functions smoothly, locking into the ceramic deployant clasp.
Why BBF for This Reference?
Many collectors ask: “Why not WWF?”
While WWF produces excellent standard Big Bangs, BBF holds the distinct advantage for the Sang Bleu II due to their proprietary gear train modifications. BBF manages the weight of the geometric discs much better, resulting in less vertical play in the hands and a more stable amplitude compared to rival versions.
Full Disclosure: The mass of the geometric disc hands requires significant torque. Leaving the chronograph running continuously will noticeably drain the power reserve and may cause the movement to stop prematurely.

Collector Q&A
Q: Does the flyback chronograph function identically to the genuine HUB1240?
A: Yes, the BBF clone movement supports true flyback functionality. This allows the user to reset and restart the chronograph instantly with a single press of the lower pusher, bypassing the traditional stop-reset-start sequence.
Q: How are the time-reading geometric discs aligned on this replica?
A: BBF utilizes a custom gear train specifically designed to support the heavy octagonal discs. The alignment is carefully calibrated to match the genuine Sang Bleu II, though the complex overlap means reading the exact minute requires familiarization with the dial’s geometry.
Q: Is the case genuine ceramic or PVD-coated steel?
A: The case is constructed from true high-tech black ceramic, utilizing a highly complex 12-piece modular construction. This accurately mirrors the genuine Hublot architecture and provides the correct scratch resistance and weight profile.
Q: What is the primary known limitation of this specific BBF Sang Bleu II replica?
A: Due to the significant mass of the geometric disc hands, the movement requires unusually high torque to operate. Leaving the chronograph running continuously will notably drain the power reserve and may reduce balance amplitude, occasionally causing the watch to stop prematurely.
