The Hublot Spirit of Big Bang first came out in 2014 as an alternative to the classic Big Bang. It has a unique barrel-shaped case and shares many features with its inspiration. The one we're looking at here has a 45mm case and runs on the self-winding HUB4700 movement. Its reference number is 601.NX.0173.LR and it has a sleek titanium case. To top it off, it comes with a cool black strap.
