The Big Bang Unico made its debut in 2013, with a self-winding chronograph movement crafted by Hublot. The name 'Unico' pays homage to this impressive feat, combining the talents and equipment of the no-longer-operating BNB Concepts. One standout model, reference 411.OX.1180.RX.1704, boasts a stunning red 'King' gold case adorned with 176 dazzling diamonds. And that's not all - the bezel is also encrusted with an extra 114 diamonds, making this timepiece a true luxury statement.
