About this product
The Hublot Big Bang Unico ‘O Ka Mua 42 mm is a striking tribute to Hawaiian heritage and the spirit of “O Ka Mua”—meaning “The Brave One.” This edition features a microblasted black ceramic case with a distinctive patina potential, making each watch truly unique. Inspired by Polynesian tattoos, the blue dial reveals the HUB1280 Unico chronograph movement with a column wheel and flyback function, offering technical prowess and artistic flair. Cultural engravings enrich the ceramic bezel, while blue accents on the chronograph hands and dial bring vibrancy and depth. Paired with a black and blue lined rubber strap and a matching titanium deployant clasp, this watch fuses island tradition with cutting-edge Swiss innovation.
