What is known as the “hacking tourbillon”, permits down-to-the-second setting of the time via a newly designed system of levers. The result is a technically sophisticated and optically balanced complication.
The fully fledged tourbillon was integrated to replace the small seconds at “6 o’clock”. By pulling out the crown, two levers grasp the balance rim and bring the balance and the entire train, including the seconds display of the chronograph, to a halt. This function enables setting the time with extreme accuracy.
To compensate the increased energy used by this newly designed tourbillon, the pallet and escape wheel are made of diamond-coated silicon to reduce friction, an extremely hard surface with good sliding properties, making it possible to retain the original 68-hour power reserve when fully wound.
