About This Piece

Poised. Technical. Undeniably bold. The Hublot Big Bang Unico Chronograph in Titanium and Blue Ceramic Watch isn’t here to blend in. With its 44mm case crafted from lightweight titanium and blue ceramic, this is a timepiece that speaks fluent innovation. Pair that with a skeletonised dial framed by sapphire crystal, and you’ve got front-row access to the HUB1280 UNICO self-winding chronograph movement - crafted with a seriously impressive 354 components and a 72-hour power reserve that’s as hardworking as it is head-turning. If that’s not enough to win you over, we don’t know what will.

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.

The deep blue detailing doesn’t stop at the bezel - it flows right through the dial’s architecture and down to the structured rubber strap, delivering cohesion with a twist of cool. And with 100m of water resistance? This one’s ready for your 9-to-5, your post-work swim, and everything in between. So you won’t ever have to take it off - and why would you want to?
