BBF Edition — Black Rubber Deployant Strap
The BBF iteration of the Big Bang Unico Sang Bleu II 418.OX.1108.RX.MXM19 represents a significant technical milestone in the replication of Maxime Plescia-Büchi’s complex geometric architecture. Unlike earlier attempts that relied on decorative plates over standard chronographs, this release integrates a true clone of the HUB1240, ensuring the correct sub-dial spacing and functioning flyback mechanism. Forum consensus consistently highlights BBF’s precision in machining the multifaceted King Gold-tone case, capturing the aggressive angles of the genuine article.
At the core of this reference is the Clone HUB 1240 automatic flyback movement, featuring the distinctive 4.5-digit hollow calendar circle. The architecture mirrors the genuine layout, allowing the semi-toothed crown tattoo logo to align correctly, while delivering approximately 36 hours of power reserve. The skeletonized dial reveals the intricate mechanics beneath, complemented by sandblasted pattern pointers and subtle emerald-toned dial accents that add depth to the geometric display.
Measuring exactly 45mm in diameter and 16.6mm thick, the case proportions align strictly with factory specifications. The total weight of 153 grams reflects the use of plated base metals rather than solid 18k King Gold, resulting in a lighter wrist presence. A sapphire mirror with anti-reflective treatment ensures distortion-free viewing of the complex dial layers.
