BBF Edition — Structured Rubber Strap

The BBF execution of the Spirit of Big Bang reference 642.NM.0170.RX represents the current horological benchmark for Hublot’s tonneau-shaped chronographs. Recognized on replica forums for its precise machining of the multi-component sandwich case, this release captures the complex geometry and alternating finishes of the genuine piece. The integration of the micro-blasted ceramic bezel with the grade 5 titanium chassis demonstrates a high level of manufacturing tolerance.

At the core of this model is the Clone HUB 4700 automatic movement. This caliber utilizes a heavily modified Asian 7750 architecture, featuring custom decorative plates and a skeletonized date wheel to mimic the layout of the genuine Zenith-based movement. The chronograph module is fully functional, supporting central seconds, minutes, and hours registers. Power reserve is approximately 36 hours.

The 42mm case is constructed from brushed and polished titanium, offering a lightweight yet substantial wrist presence. The sapphire dial is highly detailed, featuring applied indices and deep navy blue accents that closely match the tone of the ceramic bezel. The visible skeletonized mechanics provide the depth expected from the Spirit of Big Bang line.

• Movement: Clone HUB 4700 Automatic Chronograph — Approximately 36 hours
• Case Material: Grade 5 Titanium, 42.0mm diameter, 51.5mm lug-to-lug, ~135g
• Bezel: Micro-blasted blue ceramic with polished titanium H-screws
• Crystal: Sapphire with dual-sided anti-reflective treatment
• Bracelet: Blue structured lined rubber strap with titanium deployant clasp
• Water Resistance: 30m stated — professional pressure test recommended before swimming

This piece appeals to collectors who appreciate avant-garde, industrial case designs and skeletonized dials. It provides the complex aesthetic of a modern Hublot complication while remaining highly wearable due to the 42mm tonneau profile and titanium construction.

BBF Edition — Structured Lined Rubber Strap

BBF’s rendition of the Spirit of Big Bang 642.OL.7180.RX stands as a benchmark for tonneau-case skeletonized replicas. The integration of micro-blasted blue ceramic and Hublot’s proprietary King Gold tone requires precise manufacturing tolerances, which BBF achieves with notable accuracy.

Powered by the Clone HUB 4700 automatic movement, this piece replicates the complex skeletonized architecture of the genuine caliber. While based on a modified Asian chronograph architecture, the custom bridges and rotor closely mimic the high-beat foundation of the authentic piece. Power reserve is rated at approximately 36 hours.

The 42mm tonneau case combines 18k rose gold plating over a stainless steel core with a genuine blue ceramic bezel, secured by signature H-shaped titanium screws. The skeletonized dial features precise navy blue accents and applied indices with functional chronograph sub-dials. Finishing on the structured lined rubber strap and deployant clasp matches genuine specifications.

• Movement: Clone HUB 4700 Automatic — Approximately 36 hours
• Case Material: 18k King Gold plated stainless steel core, 42mm diameter
• Bezel: Micro-blasted and polished blue ceramic
• Crystal: Sapphire with Anti-reflective Treatment
• Bracelet: Blue structured lined rubber strap with deployant clasp

This model appeals to collectors seeking the bold aesthetic of a skeletonized Hublot tonneau without the genuine premium. It requires a confident wrist presence and pairs best with contemporary or avant-garde wardrobes.

BBF Edition — Quick-Release Fluororubber Strap

The BBF iteration of the Spirit of Big Bang 642.OX.0180.RX.1104 stands as a technical benchmark for tonneau-cased Hublot replicas. By meticulously reconstructing the complex “sandwich” case architecture, BBF achieves the exact multi-material integration of rose gold-plated titanium and resin found in the genuine article. This specific release is highly regarded on collector forums for its precise gem-setting geometry on the bezel and the tight tolerances of its one-button strap release system.

Powering the timepiece is the Clone HUB 4700 automatic movement, utilizing a reliable 28,800 vph base caliber heavily modified to simulate the skeletonized depth of the genuine El Primero-based engine. The factory has successfully replicated the custom date wheel and structural bridges, offering a visual complexity rarely achieved in closed-dial clones. Power reserve is strictly rated at approximately 36 hours under normal usage.

The 42mm barrel-shaped case exhibits a refined brushed and polished finish, accented by six signature H-shaped titanium screws. The open-worked dial is protected by an anti-reflective sapphire crystal, allowing clear visibility of the mechanical layers and subtle warm earth-toned structural accents. The synthetic diamonds on the bezel are securely set with consistent spacing, avoiding the uneven alignment often seen in lower-tier gem-set replicas.

• Movement: Clone HUB 4700 Automatic — Approximately 36 hours
• Case Material: Rose gold-plated titanium and resin, 42mm diameter
• Bezel: Rose gold-plated with synthetic diamond setting
• Crystal: Sapphire with anti-reflective treatment
• Bracelet: Customized fluororubber with original-spec folding clasp
• Water Resistance: 30m stated rating — professional pressure test recommended before swimming

This reference is suited for the collector who appreciates avant-garde horology and high-impact wrist presence. It serves as a highly capable alternative for those evaluating complex tonneau designs before committing to a genuine skeletonized piece.
