BB Factory Super Clone Hublot Big Bang Yellow Ceramic

[...]

Introduction
The Hublot Big Bang 441.CY.471Y.RX is one of the most iconic luxury chronographs, known for its bold yellow ceramic case and striking design. While the genuine version commands a premium price, BBF Factory has stepped up with a high-quality replica that captures the essence of the original. In this review, we’ll break down the key aspects of this rep, from materials to movement, and see how it stacks up against the authentic model.

Case & Materials​

The BBF replica features a 42mm yellow ceramic case, mirroring the vibrant aesthetic of the genuine 441.CY.471Y.RX. The ceramic is polished to a high shine, matching the original’s luster. Notably, the 6 H-shaped titanium screws on the bezel are accurately replicated, contributing to the watch’s industrial yet luxurious appeal.

• Case Thickness: ~14.5mm (close to gen)
• Ceramic Quality: Scratch-resistant, high-gloss finish
• Bezel: Fixed with proper screw alignment

The caseback is transparent, showcasing a modified 7750 movement (modified to resemble the HUB1280). While the gen uses an in-house movement, BBF’s version does a decent job in replicating the visual aesthetics.

Dial & Functions​

The semi-skeletonized dial is a standout feature, offering a glimpse of the movement beneath. Key details include:

• Chronograph Subdials:
• 3 o’clock: 60-minute counter (fully functional)
• 9 o’clock: Small seconds
• Date Window: Positioned at 4:30 (aligned with gen)
• Lume: Applied on hands and indices (weaker than gen but acceptable)

The yellow accents on the subdials and hands match the case, creating a cohesive look. The sapphire crystal is anti-reflective, ensuring good readability under different lighting conditions.

Movement: 7750 Modified to HUB1280​

The biggest upgrade in the BBF version is the modified 7750 movement, which now mimics the HUB1280 Unico found in the genuine model.

• Chronograph Function: Fully operational (start/stop/reset)
• Beat Rate: 28,800 vph (matches gen)
• Power Reserve: ~42 hours (gen has 72h)

While not a true Unico movement, BBF’s modification improves stability over older replicas that used standard 7750s with incorrect subdial spacing.

Bracelet & Clasp​

The rubber strap is soft, flexible, and features a deployant clasp with ceramic and titanium elements, just like the original.

• Quick-Release System: Allows easy strap changes (similar to gen’s "One Click" system)
• Engraving: "Hublot" logo is cleanly etched
  
  
  

Pros & Cons​

Pros:

• Excellent ceramic case finish
• Accurate dial layout and color matching
• Functional chronograph with improved movement
• Good strap quality with quick-release

Cons:

• Movement decoration not as refined as gen
• Lume could be stronger
• Thickness slightly noticeable (but close to gen)

Final Verdict​

The BBF Factory Hublot Big Bang 441.CY.471Y.RX is one of the best replicas available, offering 90-95% accuracy compared to the genuine model. While the movement isn’t a true Unico, the modifications make it a reliable and visually convincing alternative. If you love the bold yellow ceramic design but don’t want to spend $20K+, this rep is a solid choice.
