BBF Edition — One-Click Rubber Strap
The BBF production of the Hublot Big Bang Unico 42mm reference 441.EX.5120.RX represents a significant technical benchmark in replica colored ceramics. Unlike earlier iterations from competing facilities that relied on PVD-coated steel, this case is milled from solid, pigmented ceramic, ensuring the Sky Blue tone remains consistent throughout the material depth while offering genuine scratch resistance.
At the core of this reference is the custom HUB1280 clone caliber, a heavily modified architecture designed to replicate Hublot’s Unico 2 movement. Moving beyond standard decorated 7750 bases, BBF engineered this caliber to display the column wheel directly from the skeletonized dial side, aligning with the genuine mechanical layout. The movement delivers a power reserve of approximately 36 hours, supporting a fully functional chronograph and date complication.
The 42mm case dimensions are executed with precision, maintaining the distinct angular geometry and alternating brushed and polished finishes characteristic of the Big Bang line. The skeletonized matte dial features floating indices with correct luminescent application, providing a deep architectural view into the movement mechanics beneath a double AR-coated sapphire crystal.
