The Bigger Bang is the first Tourbillon Column-Wheel Chronograph with direct coupling on a flying tourbillon cage, the latest brainchild to emerge from the master watchmaker's workshop at Hublot. The chronograph mechanism and column-wheel are for the first time directly visible via the dial at 12.00 o'clock. The wearer can admire the fine execution of each component, observe the chronograph being activated by pressing the first push-piece, and see the operation of the column-wheel mechanism, the heart that beats at the centre of the system. Using the same push-piece to reset to zero causes the mechanism to stop, due to the rotary movement of the coupling wheel engaging with the Tourbillon system.
