BBF Hublot Classic Fusion Racing Grey 42mm Titanium
A technical achievement in titanium machining, capturing the exact 9.4mm profile and 100.2g weight of the genuine reference.
Powered by Clone HUB 1110
The BBF edition utilizes a highly refined SW300-based clone, specifically modified to accept interchangeable original components. The movement plates and bridges feature correct SW300 internal steel stamps, representing a structural upgrade over standard Asian ETA clones. Rotor operation is smooth and efficient, providing reliable daily performance while maintaining the slim architecture required for the 9.4mm case.
⏱ Accuracy Profile:
Regulated to ±5–8 seconds per day, consistent with high-tier SW300 clone calibers.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Hours, minutes, sweep seconds, and date
- ✅ Winding Direction: Bidirectional

Why BBF for This Reference?
Many collectors ask: “Why not WWF or JJF?”
BBF’s primary advantage lies in its obsessive adherence to the 9.4mm thickness and the precise 100.2g weight, achieved through superior titanium alloy sourcing. Rival factories often struggle with the SW300 integration, resulting in a slightly thicker mid-case that alters the watch’s intended elegant profile.
Full Disclosure: The leather-on-rubber hybrid strap requires a break-in period of a few days to conform perfectly to the wrist, and the rotor can exhibit slight acoustic feedback in quiet environments.

Collector Q&A
Q: Does the BBF Classic Fusion use genuine titanium?
A: Yes, the BBF edition utilizes genuine titanium for the case and bezel, which is how it achieves the highly accurate 100.2g total weight, identical to the genuine 542.NX.7071.RX.
Q: Are the H-screws on the bezel aligned symmetrically?
A: No, and they shouldn’t be. Just like the genuine Hublot Classic Fusion, the H-shaped titanium screws are threaded directly into the bezel and will sit at random angles. Symmetrical alignment is actually a sign of a low-tier replica.
Q: Can I swap the clone HUB 1110 movement parts with genuine Sellita SW300 parts?
A: Yes, the BBF clone movement is architecturally identical to the SW300 base used in the genuine HUB 1110. Key components, including the reversing wheels and mainspring barrel, are interchangeable.
Q: What is the main flaw with this specific BBF release?
A: The most notable quirk is the stiffness of the factory rubber/leather hybrid strap out of the box, which requires a few days of wear to mold to the wrist. Additionally, the rotor can be slightly audible in dead-silent environments, a known trait of cloned SW300 calibers.
