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.

With a sturdy titanium bezel that stunning, this timepiece goes for opulence from start to finish. And for a sleek feel to accompany the extravagant design? You can count on the lined black rubber straps for unparalleled comfort, too.
