BB Factory Hublot BIG BANG Soul Hollow Dial In-depth Review

When it comes to high-end replica watches, BB Factory (BBF) has established itself as one of the top-tier manufacturers, especially for Hublot models. Today, we’re taking a deep dive into their Big Bang Spirit 642.OM.0180.RX replica—a watch that mimics the bold, avant-garde design of the original while offering impressive craftsmanship at a fraction of the price.

1. Introduction to the Hublot Big Bang Spirit Series​

The Big Bang Spirit collection is Hublot’s take on the classic Big Bang series but with a barrel-shaped (tonneau) case, giving it a more distinctive and futuristic appeal. The genuine 642.OM.0180.RX features a skeletonized dial, titanium case, and a striking blue rubber strap, making it a favorite among luxury watch enthusiasts.
Now, BB Factory has attempted to replicate this model with remarkable accuracy. But how close does it get? Let’s break it down.

2. Case & Build Quality​

Material & Finishing​

• The genuine Big Bang Spirit 642.OM.0180.RX uses titanium for the case and bezel, known for its lightweight yet durable properties.
• The BBF replica also employs high-grade titanium, matching the weight and finish of the original. The brushed and polished surfaces are well-executed, with no rough edges.
• The six H-shaped screws on the bezel are correctly positioned, a signature Hublot detail that many replicas fail to replicate accurately.

Dimensions​

• Case Size: 42mm (same as gen)
• Thickness: ~14mm (very close to the original)
• Weight: The titanium construction ensures it feels light on the wrist, just like the authentic version.

Water Resistance​

• The genuine model is rated for 100m water resistance, but the BBF replica is likely around 30-50m (suitable for daily wear but not deep diving).
  
  
  

3. Dial & Movement​

Skeletonized Dial Accuracy​

• The openworked dial is one of the most complex aspects to replicate. The BBF version does an excellent job mimicking the multi-layered skeletonization of the original.
• The subdials (30-min counter at 3 o’clock, small seconds at 9 o’clock, and 12-hour counter at 6 o’clock) are correctly placed.
• The date window at 4:30 is present but slightly less refined than the gen.
  
  
  

Movement: BBF’s Clone vs. Genuine HUB4700​

• The authentic watch uses the HUB4700 automatic movement, based on Zenith’s El Primero (high-beat, 36,000 vph).
• The BBF replica uses a modified Asian 7750 movement with a decorated rotor to mimic the HUB4700’s appearance.
• Pros: Reliable, functional chronograph, smooth sweeping seconds.
• Cons: The beat rate is lower (28,800 vph vs. 36,000 vph), so the chronograph hand doesn’t move as smoothly as the gen.
  

4. Strap & Clasp​

• The genuine model comes with a blue structured rubber strap and a titanium deployant buckle.
• The BBF replica includes a high-quality rubber strap that closely matches the texture and flexibility of the original.
• The “One Click” quick-release system works well, allowing easy strap changes (a feature many replicas struggle with).
  
  

5. Comparison with Other Replica Factories​

BBF is not the only factory producing Hublot Big Bang Spirit replicas. Here’s how it stacks up against competitors:

Dial Accuracy	95% (excellent skeletonization)	90% (minor flaws)	85% (less refined)

Strap Quality	High-grade rubber (near gen)	Good rubber (slightly stiff)	Basic rubber (less premium)

Verdict: BBF offers the best balance of accuracy and affordability in this model.
