Tourbillon Souverain

THE NEW GENERATION OF TOURBILLON SOUVERAIN
In 1999, François-Paul Journe launched his F.P.Journe –Invenit et Fecit– brand with the Tourbillon Souverain, the first model in the Souveraine collection and the only wristwatch tourbillon watch with a constant force device. A mechanism "Invenit et Fecit" – invented and made – by François-Paul Journe, providing unique timekeeping performances for this tourbillon, which is still the most accurate on the market today.

Driven by his thirst for timekeeping research and his creative needs, François-Paul Journe now presents the new generation of the Tourbillon Souverain, in the shape of the: Tourbillon Souverain à remontoir d’égalité avec seconde morte This model replaces the existing Tourbillon Souverain with remontoir and places the latter in the category of collector's watches.

The fact that production of this first tourbillon model has been limited to just a few hundred confers on it a rare and now highly sought-after status. The new Tourbillon Souverain is endowed with the aesthetic characteristics and technical demands inherent to creations by F.P.Journe – Invenit et Fecit.
