Description
BBF Hublot Big Bang Unico Sang Bleu II Grey Ceramic 45mm
A precise execution of multi-faceted ceramic geometry and skeletonized chronograph architecture.
Powered by Clone HUB 1240
The engine driving this complex display is the clone HUB 1240 automatic flyback chronograph. BBF has engineered this caliber to visually and mechanically emulate the UNICO base, integrating the horizontal clutch mechanism visible on the dial side at the 8 o’clock position. The movement supports the unconventional geometric disc time-telling system, ensuring adequate torque to drive the heavy rhombus and hexagonal hands. The skeletonized date ring is fully functional, reading correctly through the aperture at 4:30.
Rated at ±10–15 seconds per day. Given the added mass of the geometric handset and the integrated chronograph module, amplitude may vary slightly depending on the state of wind and chronograph engagement.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Flyback chronograph, geometric hour/minute display, skeletonized date
- ✅ Winding Direction: Unidirectional
Technical Specifications
The 45mm case is constructed from multiple independent ceramic components, requiring exact tolerances to align the intricate facets and chamfers without gaps.
Time is displayed via rotating geometric discs. The dial depth is impressive, exposing the underlying gear train and the subtle grey and metallic structural bridges.
Fixed grey ceramic bezel featuring the signature Hublot H-shaped titanium screws, aligned with alternating polished and satin-brushed finishes.
Structured rubber strap featuring an embossed geometric pattern that flows seamlessly from the case lugs, secured by a robust deployant clasp.
Why BBF for This Reference?
Many collectors ask: “Why not WWF or other Hublot clone makers?”
BBF currently holds the monopoly on high-end Sang Bleu II ceramic replicas due to their mastery of the 12-piece ceramic case construction. While lesser factories use PVD-coated steel or simplified single-piece molds to cut costs, BBF machines individual ceramic components to achieve the exact sharp angles and deep textures of the genuine Maxime Plescia-Büchi design. Furthermore, their HUB 1240 clone movement integrates the visible dial-side mechanics far more accurately than standard 7750-based alternatives.
Full Disclosure: The added mass of the heavy geometric hour and minute discs creates slightly more friction than traditional hands, which can result in a marginally lower amplitude when the power reserve drops below 30%.

Collector Q&A
Q: How do you read the time on the Sang Bleu II geometric discs?
A: The time is read via the luminous tips of the rotating geometric discs. The largest outer rhombus indicates the hours, the smaller inner rhombus indicates the minutes, and the central sweeping hand functions as the chronograph seconds indicator.
Q: Is the BBF case made of real ceramic or coated steel?
A: The BBF edition utilizes genuine grey ceramic constructed from 12 individual pieces. It is not PVD-coated steel, ensuring the same scratch resistance, weight profile, and sharp faceted finishing as the original.
Q: Does the flyback chronograph function work on the clone HUB 1240?
A: Yes, the flyback mechanism is fully operational. Pressing the lower pusher at 4 o’clock while the chronograph is running will instantly reset the seconds hand to zero and immediately restart the timing without needing to stop it first.
Q: What is the primary limitation of this BBF Sang Bleu II replica?
A: Due to the substantial weight of the geometric disc hands compared to traditional hands, the movement requires more torque. This results in a lower power reserve of approximately 36 hours, and the rotor mechanism can be slightly more audible than the genuine UNICO caliber.
