In 2019, Hublot released the Spirit of Big Bang 39, a sleek and feminine version of their popular Spirit of Big Bang watch. This new model has a smaller 39mm case and features a self-winding movement with central seconds and a date display. For a touch of luxury, the Reference 665.OX.9010.LR.1604 comes with a diamond-set case, bezel, and dial. It's finished off with a stylish leather strap.
