To celebrate the 20th anniversary of their tourbillon movement in 2019, F.P. Journe launched a reinvented version of its iconic Tourbillon Souverain: The Tourbillon Souverain Vertical. The main intuition behind the new movement is as simple as it is powerful: a normal tourbillon has to lay perpendicular to gravity in order to "work its magic" - to average out gravity disturbances on the oscillations. That means that in a normal tourbillon configuration, with the tourbillon positioned parallel to the dial, when one leaves the watch lying flat on its back (or on its crystal), the tourbillon is not working because its rotation is parallel to gravity. By rotating the cage 90 degrees, the tourbillon instead becomes sensitive to gravity even if - actually, especially if - the watch is lying flat. Furthermore, as a wristwatch practically never stays perfectly vertical even if set on its side (due to the bracelet/strap usually inducing an inclination), the new Tourbillon Souverain Vertical renders the tourbillon effective in virtually any position the watch can acquire when set down.

On top of that, the new rotational speed of the cage - now twice as fast as the original model - and the polished sides - both on the dial and on the movement side as well - of the tourbillon cradle grant the beholder an incredibly dynamic and mesmerizing mechanical show.

Keeping with the Journe Tourbillons from the brand's inception the watch keeps the signature constant force escapement mechanism: the remontoir d'égalité.

The movement is beautifully finished, the 18k pink gold plates and bridges are decorated with circular Geneva stripes, polished bevels, black polished steel parts and perlage. The vertical tourbillon is also equipped with a second reflector, which was created on the movement side to provide light around the tourbillon cage, as well as providing a better view of its motion.
