Bulgari BVL 388

World record-setting ultra-thin automatic tourbillon chronograph. At 3.5mm thick, it is the thinnest tourbillon chronograph movement ever made, enabling a 7.4mm case. Unlike previous Finissimo tourbillons, it uses a bridge-mounted (not flying) tourbillon at 6 o'clock. Features a monopusher column wheel chronograph with horizontal clutch, 30-minute counter at 3 o'clock, small seconds at 9 o'clock. Pusher at 4 o'clock stops the rotor for time setting. Only available in skeleton form.
