Hublot Big Bang Unico SR_A by Samuel Ross All Black 42 mm 441.CX.1140.RX.SRA26 Limited Edition

The Big Bang Unico SR_A by Samuel Ross All Black is the first SR_A model to use Hublot's Unico chronograph movement, following three earlier SR_A tourbillon editions created with the British designer since 2020. Limited to 200 pieces, it is rendered entirely in black: a 42 mm case in satin-finished and polished black ceramic, a matching bezel with six H-shaped black-plated titanium screws, and a matte black skeleton dial.

Samuel Ross's signature honeycomb motif appears on the black structured rubber strap developed for this reference. Inside is the HUB1280 UNICO manufacture self-winding flyback chronograph with column wheel and silicon escapement, with a power reserve of approximately 72 hours. The case is water-resistant to 100 m (10 ATM).
