Introduced in 1999, the Tourbillon Souverain is the first tourbillon wristwatch in the collection enriched with dead beat seconds and remontoir, which provides a constant force to the balance and hence maintaining a more accurate read of precise time. The dead beat seconds mechanism allows the hands to move in steps from one second to another, which helps increasing the precision and accuracy. This present watch is endowed with the aesthetic characteristics and technical demands inherent to creations by F.P. Journe, giving the watch a highly sought-after status.
