Hublot Big Bang Sapphire All Black

About this reference

Released in 2016 to commemorate the 10th anniversary of the All Black concept, the Hublot Big Bang Unico Sapphire All Black (reference 411.JB.4901.RT) was produced as a limited edition of 500 pieces. It is no longer in production. Collectors value this reference for its technical construction, featuring a case, bezel, and case back machined from blocks of smoked black sapphire crystal. It houses the in-house HUB1242 Unico movement, an automatic flyback chronograph with a column wheel visible through the skeletonized dial. The watch represents a significant milestone in the brand's history of material innovation, specifically the industrialization of shaped sapphire. On the secondary market, this reference typically trades between $45,000 and $65,000 depending on condition and provenance. While most Big Bang models utilize ceramic or gold, this specific 45mm variant remains a primary example of the brand’s transparent monochromatic design language.
