I was in the Jaeger-LeCoultre manufacture recently and captured this short clip of both the Gyrotourbillon 1 (on the left) and Reverso Gyrotourbillon 2. The Gyrotourbillon is JLC’s most important and successful high complication wristwatch, and a real treat to watch. Even though the motion of the tourbillon is visually identical, the tourbillons are not. The Gyro 1 has a flat hairspring and the Gyro 2 a cylindrical hairspring. This video provides a closer look at the Gyrotourbillon 2. And fans of the Gyro will want to take a much closer look at the Gyrotourbillon 2 in rose gold. – SJX
