F. P. Journe Tourbillon Souverain

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.
