BBF Edition — Structured Rubber Strap
The BBF Hublot Square Bang Unico represents a significant technical milestone in replicating Hublot’s complex, multi-layered sandwich case geometry. By successfully integrating micro-blasted blue ceramic with a proprietary 5N rose gold plating that closely mimics Hublot’s King Gold, BBF delivers a highly convincing alternative to the genuine reference 821.OL.5180.RX.
At the core of this model is the Clone HUB 1280 automatic movement. BBF has engineered the skeletonized dial to display the intricate gear train and a simulated dial-side column wheel, maintaining the visual depth characteristic of the Unico caliber. Power reserve is rated at approximately 36 hours.
The case measures a precise 42mm in diameter with a verified thickness of 15.6mm, weighing in at a substantial 158.4g. The dial features accurate deep blue accents on the sub-dials and chapter ring, while the brushed and polished finishing on the ceramic bezel aligns correctly with the six signature H-shaped titanium screws.
