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.

Prepare to be swooned by the prominent blue, intricately incorporated onto the components on the dial, which also colours the structured, lined rubber straps. And for a captivating finishing touch? The six identical H-shaped titanium screws on the titanium bezel are a legendary Hublot staple which will forever remain iconic.
