Description
BB Factory Hublot Big Bang Unico White Ceramic 42mm
A definitive step forward in material engineering and movement architecture for the Unico platform.
Powered by Custom HUB1280 Clone
The horological core of this reference relies on a fully customized movement designed to replicate the genuine HUB1280 Flyback Chronograph. By abandoning the traditional Asian 7750 with superficial decorative plates, BBF provides a skeletonized view where the gears and bridges match authentic placement data. The integration of the chronograph module into the base architecture ensures stable pusher engagement while maintaining the required visual depth.
Regulated at the factory to approximately ±8–12 seconds per day. The customized gear train requires a stable power state for optimal amplitude, characteristic of complex clone chronographs.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Fully functional chronograph, skeletonized date wheel
- ✅ Winding Direction: Unidirectional
Technical Specifications
Constructed to exact 42mm proportions with a verified thickness of 15.2mm. The inner chassis utilizes Grade 5 Titanium to anchor the movement, ensuring structural rigidity while maintaining a total weight of just 131.9 grams.
Features accurate depth layering with the date ring fully visible. The hands utilize a distinct prismatic, seven-color texture to catch light, complemented by crisp white-tone numerical appliques.
Highly scratch-resistant ceramic insert secured by six functional, polished H-shaped titanium screws. The contrasting brushed and polished facets are executed with strict adherence to genuine tolerances.
Integrates Hublot’s proprietary One-Click quick release system, allowing seamless strap changes. Secured by a titanium deployant buckle mechanism.
Why BBF for This Reference?
Many collectors ask: “Why not V6F?”
Older V6F iterations relied heavily on standard Asian 7750 movements fitted with superficial decoration plates. This resulted in an incorrectly positioned balance wheel and excessive case thickness. BBF’s custom HUB1280 clone resolves these fundamental architectural flaws, offering genuine-spec skeletonization and a more accurate 15.2mm profile.
Full Disclosure: The custom clone movement exhibits slightly more rotor noise during rapid wrist movements compared to the authentic caliber, a common trait of unshielded ceramic ball bearings in replica chronographs.

Collector Q&A
Q: Does the One-Click strap release system function like the authentic model?
A: Yes, BBF has accurately replicated the proprietary One-Click trapezoidal mechanism. This allows for quick interchangeability and is compatible with genuine Hublot 42mm Unico straps.
Q: Is the skeletonized date wheel fully operational?
A: Yes. The date wheel is fully skeletonized and advances mechanically, exactly mirroring the visual depth and functionality of the genuine HUB1280 caliber.
Q: Will the white ceramic case discolor or scratch over time?
A: No. Because BBF utilizes true sintered high-tech ceramic rather than a surface coating, the material is highly scratch-resistant and UV-stable. It will not yellow, fade, or show steel underneath if impacted.
Q: What is the most notable flaw on this BBF replica?
A: The primary horological tell is the rotor winding noise. The custom HUB1280 clone utilizes an unshielded bearing track that produces a distinct whirring sound during rapid wrist movements, which is quieter on the authentic caliber.
