Description
BBF Hublot Big Bang Unico Sang Bleu II 45mm Green Ceramic
An uncompromising technical execution of Hublot’s most complex geometric case architecture.
Powered by Clone HUB 1240
The BBF edition utilizes a heavily modified automatic chronograph base to replicate the visual layout of the genuine HUB 1240 Unico movement. This clone caliber successfully drives the complex geometric disc hands—a notoriously difficult feat due to the mass of the hands themselves. It retains the 60-minute timing function at the 3 o’clock position and features the skeletonized date wheel visible through the dial geometry.
±10–15 seconds per day. The increased torque required to rotate the geometric hands can cause slight positional variance, which is acceptable for this specific clone architecture.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Chronograph, skeletonized date, geometric time display
- ✅ Winding Direction: Unidirectional
Technical Specifications
Constructed from 12 separate ceramic components, the 45mm case features sharp transitions between satin-brushed surfaces and polished chamfers, mimicking the genuine case density.
Features layered rhombuses and hexagons with green ceramic tone accents. The alignment of the central spinning seconds disc is precise, though legibility remains inherently challenging.
Secured via six H-shaped titanium screws. The alternating finishes on the multifaceted bezel are sharply defined, avoiding the rounded edges seen on lower-tier replicas.
Black rubber with geometric structural lines, secured by a ceramic and titanium deployant clasp. Features the quick-release mechanism for easy strap changes.
Why BBF for This Reference?
Many collectors ask: “Why not King Factory or WWF?”
While other factories produce standard Big Bang models, BBF is the undisputed leader for the Sang Bleu II architecture. Their mastery of the 12-piece ceramic construction ensures that the intricate, sharp geometric lines designed by Maxime Plescia-Büchi are not lost to over-polishing, a common issue with rival factories attempting this case shape.
Full Disclosure: The rotor on the heavily modified HUB 1240 clone movement exhibits noticeable bearing noise in quiet environments, a known trait of this specific movement architecture.

Collector Q&A
Q: Is the ceramic case on the BBF Sang Bleu II genuinely scratch-resistant?
A: Yes. BBF utilizes real sintered ceramic for the 12-piece case construction, providing the same high scratch resistance and thermal properties as genuine ceramic, rather than a PVD-coated steel substitute.
Q: How do you read the time on the geometric dial?
A: The time is indicated by the luminescent tips on the geometric discs. The largest outer triangle indicates the hours, the medium inner triangle indicates the minutes, and the smallest central disc acts as the running seconds indicator.
Q: Does the quick-release strap system function correctly?
A: Yes, the BBF edition replicates Hublot’s ‘One Click’ strap release mechanism accurately. The trapezoidal pushers on the lugs allow for tool-free removal and installation of compatible straps.
Q: What is the main drawback of the clone HUB 1240 movement?
A: Because the clone HUB 1240 is based on a heavily modified chronograph architecture designed to drive the heavy geometric discs, the rotor bearing can be noticeably loud, and engaging the chronograph pushers feels stiffer than the genuine Unico movement.
