As a highly sought-after model, it has inevitably attracted the attention of the replica watch industry. Among the top-tier replica manufacturers, BB Factory (BBF) has gained a reputation for producing some of the most accurate Hublot replicas.In this in-depth review, we’ll examine how well the BB Factory Hublot Big Bang Soul 642.NX.7170.RX holds up against the genuine model. We’ll cover:
- Case & Build Quality
- Dial & Movement Accuracy
- Bracelet & Clasp
- Functionality & Wearability
- Final Verdict: Is It Worth It?
1. Case & Build Quality
The genuine Hublot Big Bang Soul 642.NX.7170.RX features a titanium case with a black ceramic bezel, secured by 6 H-shaped screws—a signature Hublot design.BB Factory’s Replica Case:
Material Accuracy:- The replica uses grade 2 titanium for the case, matching the lightweight feel of the authentic watch.
- The ceramic bezel is well-polished, with the correct matte finish.
- The H-shaped screws are properly aligned, though some minor differences in engraving depth may exist.
Dimensions & Weight:- Case Size: 42mm (same as gen)
- Thickness: ~14.1mm (very close to gen)
- Weight: Slightly lighter due to different titanium alloy, but barely noticeable.
Minor Flaws:- The brushing and polishing on the case edges may not be as refined as the genuine model.
- The bezel screws might have slightly less precision in their fit.
2. Dial & Movement Accuracy
The genuine Big Bang Soul has a skeletonized dial with a blue-tinted movement and luminescent markers.BB Factory’s Replica Dial:
Skeletonized Design:- The open-worked dial is well-executed, with correct blue accents on the movement plates.
- The subdials (30-min counter at 3 o’clock, small seconds at 9 o’clock) are accurately placed.
Lume & Markers:- The applied hour markers have decent lume, though slightly weaker than the gen.
- The hands are well-shaped, with proper lume fill.
Movement Differences:- The genuine watch uses the HUB4700 (based on Zenith El Primero), while the BBF replica uses a modified Seiko chronograph movement (likely the VD78).
- The subdial spacing is slightly off, but only noticeable upon close inspection.
- The rotor noise is louder than the gen.
3. Bracelet & Clasp
The genuine model comes with a black rubber strap + titanium deployant clasp.BB Factory’s Bracelet:
Rubber Strap Quality:- The texture and flexibility are very close to the original.
- The stitching and finishing are clean.
Deployant Clasp:- The titanium clasp is well-engraved with Hublot branding.
- The locking mechanism is secure, though slightly less smooth than gen.
Minor Issues:- The rubber strap may feel slightly stiffer initially but softens with wear.
- The clasp screws might loosen over time (common in replicas).
4. Functionality & Wearability
- Chronograph Function: Works smoothly, but pusher action is not as refined as the gen.
- Water Resistance: ~30m (splash-proof, but not for swimming).
- Comfort: Lightweight and sits well on the wrist, just like the original.
Final Verdict: Should You Buy It?
The BB Factory Hublot Big Bang Soul 642.NX.7170.RX is one of the best replicas available. It nails the case construction, dial aesthetics, and strap quality, though the movement and minor finishing details are not perfect.Pros:
✔ Extremely close to gen in appearance✔ High-quality titanium & ceramic build
✔ Good strap and clasp replication
Cons:
Movement is not a true clone Some minor finishing flawsRating: 8.8/10 – A fantastic rep for Hublot enthusiasts who want the look without the $20K+ price tag.
