About This Piece

A watch that is every bit as outré as the brand itself, this Hublot Big Bang Unico Sapphire Automatic chronograph is a limited edition of just 500 pieces and it's one we want to get our hands-on. Watch each beat of the UNICO 2 calibre through the skeleton dial and open caseback and sapphire crystal case; they certainly like to keep things transparent at Hublot. A true statement piece but with all the robustness you’d expect from the Big Bang collection.

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.

We love the talking point appeal of this timepiece, a bold and innovative watch with its unique ‘glass’ case. Plus the 72 hour power reserve means you’ll never be out of time.
