**Tourbillon Souverain** is a luxury wristwatch by [[F. P. Journe]].

For this world's first wristwatch with [[tourbillon]] and uniform force supply ([[constant force]]) [[F. P. Journe]] received the main prize "Golden hand" at the prestigious [[Grand Prix d'Horlogerie de Genève]] in [[2004]]. The watch has the unusual complication of a [[dead-beat second]] (//seconde morte//), pausing on the second and then jumping to the next second. Also this watch creation of the master embodies the usual classical quality claim.
