About This Piece

Utterly outrageous - in the best way possible - this Hublot Square Bang Unico Ceramic Chronograph Automatic Watch showcases contemporary watchmaking like you’ve never seen it before. Its monochromatic 42mm black ceramic square case and matching black lined rubber straps make a defining setting for that showstopper of a dial. Prepare to bear witness to the HUB1280 UNICO self-winding chronograph flyback movement, complete with a column wheel and power reserve of 72 hours. Impressive, right? With a water resistance of 100m, this one’s as resilient as it looks.

Editor's Notes


If offbeat is your thing then the Hublot Big Bang collection is made for you. When a watch is described as a state of mind, you know you’re on to a good thing and this collection is more than good. Much more. Inspired by the moment the universe and all its materials came together (a.k.a the Big Bang), this range is Hublot’s flagship model. And with the iconic porthole design used throughout Hublot’s watches (did you know that Hublot means porthole in French?). A Big Bang timepiece is a must for any true horology fan.

If you’re someone who likes your timepiece to double as a real talking piece, this one’s for you. It’s the audacious, meticulously crafted design that wins us over every time.
