In 2019, Hublot released the Spirit of Big Bang 39, a watch designed with a touch of femininity. This version features a smaller 39mm case, a change from the original model. The watch runs on a self-winding movement, displaying central seconds and date. The reference 665.NE.2010.LR.1604 boasts a titanium case covered in diamonds, with a white strap and dial to match.
