In 1999, François-Paul Journe launched the first Tourbillon Souverain with remontoir d’égalité in wristwatch form. To celebrate the 20th anniversary of this emblematic wristwatch, F.P.Journe has developed a tourbillon whose cage is vertical, rather than the traditional horizontal cage. “I designed this vertical tourbillon so that the tourbillon’s functions remain constant whether the watch lies flat or is placed on its side, and the amplitude is consequently the same, whether the watch has a deployant clasp and lies on its side or an ardillon buckle and lies flat,” he says. This vertical tourbillon with remontoir d’égalité and deadbeat second makes one revolution every 30 seconds. This is faster than the usual time of one minute, making the technical prowess even more visually astonishing.
Surrounding the cage, a cone-shaped mirror-polished ring concentrates light, reflecting the tourbillon cage. A second reflector was created on the movement side to provide light around the tourbillon cage. The 4N rose Gold bridges that form the dial are decorated with “Clous de Paris” guilloche with, for the first time, an enamel hour dial at 3 o’clock. The Tourbillon Vertical also features an 80-hour power reserve at 12 o’clock and small seconds at 6 o’clock; the remontoir d’égalité is placed at 7 o’clock. The 42-mm case is available in platinum or in 18k 6N Gold.
