The new Gyrotourbillon version features a key component that sets it apart: a cylinder-shaped balance-spring with curved ends. This was first created by English watchmaker John Arnold and patented in 1782. It was originally used in marine chronometers and larger pocket watches due to its complexity and difficulty to miniaturize. However, the engineers and watchmakers at the Manufacture saw the potential of combining this ingenious discovery with the spherical tourbillon in a wristwatch. The result is a groundbreaking advancement in accuracy, allowing for unprecedented precision in timekeeping even with the movement of the wearer's arm.
