Tourbillon Souverain Ref. TN
Introduced in 2004, the 'Reference TN' for 'Tourbillon Nouveau' is the direct descendant of the celebrated ‘Reference T’ - F.P. Journe’s first production watch but also the very first wristwatch ever to use a constant force remontoire. The Tourbillon Souverain, undoubtedly one of the greats among F.P. Journe's horologic masterworks, is distinguished by its complications, combining a one-minute tourbillon with a constant force remontoir. The remontoir provides a constant force to the balance, hence maintaining an equal rate of force whether the watch is fully wound or not and therefore increasing precision. François-Paul Journe's ingenious masterpiece is the first wristwatch to have the distinction of combining a remontoir d'égalité, dead beat seconds and a tourbillon regulator.

The Tourbillon Souverain received the Aiguille d’Or prize at the Geneva Grand Prix d’Horlogerie in 2004. It was also elected watch of the year at the 'Watch of the Year' grand prize in Japan in 2004.
