Description
BBF Hublot Square Bang Unico King Gold Blue Ceramic 42mm
BBF establishes the benchmark for the Square Bang series through precise ceramic milling and a visually accurate HUB 1280 clone architecture.
Powered by Clone HUB 1280
The engine driving this replica is a modified automatic movement designed to emulate Hublot’s in-house HUB 1280 Unico caliber. BBF has heavily customized the top plates to recreate the signature skeletonized aesthetic, positioning a simulated column wheel at the 6 o’clock position to match the genuine layout. While the underlying mechanism relies on a cam-actuated chronograph module rather than a true integrated column-wheel system, the visual depth and structural complexity viewed through the sapphire dial are highly commendable.
Standard clone base movement: ±10–15 s/day. Regulation is performed prior to assembly to ensure stable amplitude across standard wearing conditions.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Chronograph, Date display (skeletonized wheel)
- ✅ Winding Direction: Unidirectional
Technical Specifications
Features a multi-layered sandwich construction measuring 15.6mm in thickness. The proprietary 5N rose gold plating closely mimics genuine King Gold, contrasting sharply with the ceramic components.
Transparent sapphire dial reveals the modified date wheel and gear train. Features precise blue accents on the chapter ring and sub-dials with correctly applied luminous material.
Exhibits correct alternating micro-blasted and polished finishes. Secured by six functional H-shaped titanium screws that sit flush with the ceramic surface.
High-density blue rubber molded with a textured motif. Integrates seamlessly into the lug system and secures via a King Gold plated deployant clasp.
Why BBF for This Reference?
Many collectors ask: “Why not King Factory?”
While other factories produce passable Hublot models, BBF exclusively masters the complex geometry of the Square Bang. Their ceramic milling tolerances are notably tighter, eliminating the micro-gaps often seen between the bezel and the sandwich case mid-section on lesser clones. Furthermore, BBF’s dial-side decoration of the HUB 1280 is significantly more three-dimensional.
Full Disclosure: The chronograph pushers on the BBF clone feel slightly spongy upon engagement, lacking the crisp, mechanical snap characteristic of the genuine Unico movement.

Collector Q&A
Q: Does the dial-side column wheel function like the genuine HUB 1280?
A: On the BBF clone, the dial-side column wheel is largely decorative to mimic the genuine architecture, while the actual chronograph engagement occurs via a standard cam-actuated module hidden beneath the skeletonized plate.
Q: How accurate is the King Gold plating color?
A: BBF has achieved a highly accurate 5N rose gold hue that closely matches Hublot’s proprietary King Gold, though it lacks the actual platinum alloy content and density of the genuine material.
Q: Are the case dimensions identical to the genuine Square Bang?
A: The BBF case measures exactly 42mm in diameter with a verified thickness of 15.6mm. This is marginally thicker than the genuine article due to the clone movement module, but the difference is extremely difficult to detect on the wrist.
Q: What is the most notable flaw on this specific replica?
A: The primary tell is the tactile feedback of the chronograph pushers. While fully functional, they lack the crisp, immediate mechanical snap found on the genuine Unico movement, feeling slightly softer upon engagement.
