Original price was: $1,300.00.Current price is: $1,029.00.

BBF Edition — Structured Rubber Strap

BBF’s iteration of the 42mm Big Bang Unico represents a significant step in skeletonized dial replication. By utilizing genuine Grade 5 titanium, the factory achieves the exact tactile feel and weight distribution expected from the 441 series, avoiding the top-heavy imbalance found in earlier steel-based clones.

The customized HUB1280 automatic chronograph movement features a functioning column wheel visible from the dial side. Unlike standard modifications that merely glue decorative plates, BBF has re-engineered the top bridge layout to closely mimic the genuine Unico architecture. Power reserve is approximately 36 hours.

Measuring exactly 42mm in diameter and verified at 15.8mm thick, the case exhibits a precise alternating brushed and micro-blasted finish. The skeleton dial integrates a deep maritime blue accent that accurately matches the polished blue ceramic bezel. The one-button quick-release strap mechanism operates with tight tolerances, ensuring secure integration.

Description

BBF Hublot Big Bang Unico Titanium Blue Ceramic 42mm 441.NL.5171.RX

BBF establishes the benchmark for the 42mm Unico series by successfully integrating Grade 5 titanium with a structurally complex HUB1280 clone movement.

Powered by Clone HUB1280

The BBF HUB1280 clone is a heavily modified automatic chronograph caliber designed to replicate Hublot’s in-house architecture. The most notable technical achievement is the relocation of the column wheel to the 6 o’clock position on the dial side, which actively engages when the chronograph pushers are actuated. The skeletonized rotor spins smoothly, winding the mainspring to power the complex gear train visible through the sapphire crystal.

⏱ Accuracy Profile:

Regulated to ±10–15 seconds per day, which is standard and acceptable for modified 7750-based chronograph clone architectures.

  • ✅ Power Reserve: Approximately 36 hours
  • ✅ Complications: Hours, minutes, sub-seconds, date display, and fully functional chronograph
  • ✅ Winding Direction: Unidirectional

Technical Specifications

THE BUILDGrade 5 Titanium

The sandwich case construction utilizes Kevlar-style lateral inserts. Thickness is verified at 15.8mm, presenting a robust yet lightweight profile on the wrist.

THE DIALSkeletonized Matte Black & Maritime Blue

The dial plate features applied Arabic numerals with precise luminescent fills. The visible date wheel skeletonization is crisp, providing deep visual layering.

THE BEZELPolished & Micro-blasted Ceramic

Secured by six H-shaped titanium screws. The ceramic tone is highly accurate under natural light, avoiding the purplish hue seen in lower-tier batches.

THE BRACELETStructured Blue Rubber

Integrates Hublot’s patented one-click quick-release system. The titanium deployant clasp snaps securely without lateral play.

Why BBF for This Reference?

Many collectors ask: “Why not ZF?”

While ZF produces excellent Unico models, BBF currently holds a slight edge in the 42mm HUB1280 specific case proportions and the quick-release button tolerances. The Grade 5 titanium milling on the BBF feels marginally sharper at the lug facets, providing a more gen-like tactile experience when interacting with the strap system.

Full Disclosure: Because the movement uses a heavily modified base caliber to mimic the complex HUB1280, rotor winding noise is noticeably louder than genuine, and the case sits 1.3mm thicker than OEM specs.

Collector Q&A

Q: Does the chronograph function work like the genuine HUB1280?

A: Yes, the chronograph is fully functional. The central seconds hand tracks elapsed seconds, and the 3 o’clock sub-dial tracks elapsed minutes. The column wheel visible at 6 o’clock on the dial side actively engages when the pushers are pressed.

Q: Are the case dimensions exactly 1:1 with the genuine 441 series?

A: The case diameter is an accurate 42mm. However, due to the architecture of the modified clone movement, the thickness is verified at 15.8mm, which is approximately 1.3mm thicker than the genuine 14.5mm specification.

Q: Is the ‘One Click’ strap release system reliable on the BBF version?

A: BBF has engineered the quick-release trapezoidal buttons with strong internal springs. It holds the strap securely without the rattling or accidental deployment issues seen in earlier replica generations, allowing for safe swapping with aftermarket or genuine Hublot straps.

Q: What is the most notable flaw on this specific BBF Unico replica?

A: Because the movement uses a heavily modified base caliber to mimic the complex in-house HUB1280, the rotor winding noise is noticeably louder than genuine. Additionally, the skeletonized date wheel font is slightly thicker than the OEM printing.
