The Tourbillon Souverain, another of F.P. Journe's horologic masterworks, is distinguished by its complications, combing 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 increasing the precision.
François-Paul Journe's ingenious masterpiece is the first wristwatch combining a remontoir d'égalité, dead beat seconds and a tourbillon regulator.
