The Quadruple Tourbillon contains four tourbillons that perform perfectly together like a well choreographed ballet. Each tourbillon contains a smaller tourbillon and can be seen from the front of the dial. The Quadruple Tourbillon Blue is an absolutely stunning addition to the collection. The mirror like finish of the dial is a laborious process and makes the electric blue dial pop. Limited to 8 pieces.
