BB Factory Hublot Square Bang Unico Replica Watch Review

Introduction​

The Hublot Square Bang Unico is one of the most striking luxury sports watches in recent years, blending bold design with high-end mechanics. While the genuine version commands a hefty price tag (starting at NT$ 717,000 / ~$23,000 USD for the titanium model), the BBF Factory replica offers an intriguing alternative for enthusiasts who admire the Square Bang’s aesthetics but seek a more affordable option.
In this review, we’ll dissect the BBF Factory Hublot Square Bang Unico 821.NX.5170.RX replica, analyzing its build quality, movement, accuracy, and overall wearability.

1. Design & Case Construction​

Square Case & Materials​

The Square Bang Unico stands out with its 42mm x 42mm angular case, a departure from Hublot’s usual round Big Bang designs. The BBF replica replicates this perfectly, using titanium for the case and bezel, just like the genuine model.
Key features:

• Sandwich construction (a signature Hublot design) with polished and brushed finishes.
• Black ceramic bezel (on some variants) with six H-shaped titanium screws, mirroring the authentic watch.
• 100m water resistance—remarkable for a square case, a challenge even for genuine Hublot.
  
  

Dial & Legibility​

• Skeletonized dial with a blue-tinted Unico movement (on newer 2024 models, some replicas may follow this update).
• Luminous hour markers & hands for visibility in low light.
• Date window at 3 o’clock, matching the original layout.
  
  
  

2. Movement: Replica vs. Genuine​

Genuine HUB1280 Movement (Unico Caliber)​

• Automatic chronograph with 72-hour power reserve.
• Flyback function (allowing instant reset of the chronograph).
• Visible column wheel at 6 o’clock (a signature of high-end chronographs).

BBF Factory Replica Movement​

BBF uses a modified Asian 7750 movement to mimic the HUB1280 Unico. While not identical, it offers:

• Functional chronograph (start/stop/reset).
• Semi-skeletonized rotor to imitate the Unico’s appearance.
• Smooth seconds hand sweep (28,800 vph, matching the genuine movement).

Limitations:

• The flyback function is not replicated (standard chrono reset only).
• The finishing is less refined than the genuine Unico movement.
  
  

3. Bracelet & Comfort​

• Rubber strap with square-textured pattern, matching Hublot’s design.
• One-Click quick-release system (a patented Hublot feature for easy strap changes).
• Titanium folding clasp with secure locking.

Wearability:

• The 42mm size fits most wrists comfortably.
• The square shape is bold but not overly bulky.

4. Accuracy & Flaws​

Pros:​

✔ Case & bezel are nearly 1:1 in shape and finishing.
✔ Dial details (skeletonization, date window, subdials) are well-replicated.
✔ Functional chronograph (though not flyback).

Cons:​

✖ Movement decoration is simplified (no perlage or Geneva stripes).
✖ Rotor noise (common in Asian 7750-based replicas).
✖ No genuine ceramic option on some models (some replicas use coated metal instead).

5. Final Verdict: Is the BBF Square Bang Unico Worth It?​

For ~$400-$600, the BBF Factory Square Bang Unico is one of the best Hublot replicas available. It captures the bold design, case construction, and chronograph functionality of the genuine watch while keeping costs reasonable.
Who should buy it?

• Hublot fans who love the Square Bang’s design but can’t justify the retail price.
• Collectors looking for a high-quality replica with a reliable movement.
• Luxury watch enthusiasts who appreciate unique case shapes.

Who should avoid it?

• Purists who demand 100% movement accuracy.
• Those expecting genuine ceramic bezels (verify with the seller).
