Description
BBF Hublot Big Bang Tourbillon Automatic Black Magic 419.CI.0170.RX
The BBF release stands as the current definitive choice for the HUB6035 caliber, offering unprecedented structural fidelity in its sapphire bridges.
Powered by Clone HUB6035 Tourbillon
The movement architecture precisely replicates the linear layout of the genuine caliber, suspending the micro-rotor and tourbillon between transparent sapphire bridges. All visible gearing is functional rather than decorative, ensuring the kinetic visual impact is authentic. The automatic winding mechanism is smoothly articulated via the dial-side micro-rotor, providing reliable energy transfer to the mainspring barrel.
Regulated to ±5–8 seconds per day. Performance is highly stable for a clone tourbillon escapement, though positional variance is slightly higher than standard three-hand calibers.
- ✅ Power Reserve: Approximately 36 hours
- ✅ Complications: Flying tourbillon at 6 o’clock, functional dial-side micro-rotor at 12 o’clock
- ✅ Winding Direction: Unidirectional (micro-rotor)
Technical Specifications
Constructed with a 45mm diameter and a 15.30mm thickness. The case exhibits an accurate ratio of micro-blasted to polished surfaces, matching the genuine Black Magic aesthetic.
Features correct structural depth with precise alignment of the transparent bridges. Printed indices are crisp, and the hands are finished with accurate beveling and lume application.
Secured by six signature H-shaped titanium screws. The bezel insert maintains the correct matte tone and edge polishing, integrating seamlessly with the composite resin lower bezel.
Crafted from imported Thai rubber. The quick-release mechanism operates with minimal endplay, allowing for secure and rapid strap changes.
Why BBF for This Reference?
Many collectors ask: “Why not JB Factory?”
BBF’s primary advantage lies in the execution of the HUB6035 clone movement, specifically the integration of the sapphire bridges which JB struggled to align correctly. The BBF carriage is more refined, and the gear train operates without the decorative faux plates seen on earlier replicas.
Full Disclosure: The micro-rotor bearing noise is marginally more pronounced than the genuine article, a common trait in clone micro-rotor tourbillon movements.

Collector Q&A
Q: Does the micro-rotor at 12 o’clock actually wind the watch?
A: Yes, the BBF clone HUB6035 features a fully functional dial-side micro-rotor that actively winds the mainspring, rather than being a purely decorative element.
Q: Are the transparent movement bridges made of real sapphire?
A: The bridges on the BBF version are crafted from genuine synthetic sapphire, providing the correct refractive index and structural rigidity required for the movement architecture.
Q: Is the quick-release strap system compatible with genuine Hublot straps?
A: The BBF ‘One Click’ system is engineered to 1:1 tolerances, meaning it generally accepts genuine Hublot Big Bang 45mm straps without requiring modification.
Q: What is the most noticeable tell on this specific BBF replica?
A: While the movement architecture is highly accurate, the finishing on the tourbillon cage edges is slightly less refined under a loupe compared to the genuine, and the micro-rotor bearing emits a faintly audible whir during vigorous wrist movement.
