The Hublot Big Bang Unico made its debut in 2013, named after its impressive self-winding chronograph movement created by the brand itself. This was made possible by Hublot's use of the talented designers and machinery from the now-closed BNB Concepts. One notable variant, the 411.NX.1170.RX, boasts a sleek titanium case and a lower bezel crafted from anodized aluminum.
