The Big Bang Unico Yellow Magic 44 mm is a bold and vibrant statement piece, combining technical innovation with unmistakable style. Made from patented Yellow Magic ceramic, this watch showcases a bright, high-gloss yellow case and bezel that’s as scratch-resistant as it is visually striking. The openworked dial reveals the in-house HUB1280 Unico movement, a self-winding chronograph with flyback function, column wheel, and a 72-hour power reserve. Yellow accents and black PVD components add contrast and depth to the futuristic aesthetic. Paired with a structured yellow rubber strap and black ceramic/titanium deployant clasp, this limited-edition piece embodies the spirit of “The Art of Fusion” in vivid color.
