The Tourbillon Souverain d'Egalité marked a significant milestone in the evolution of wristwatches with the integration of a constant force remontoire mechanism. This groundbreaking innovation, combined with the intricate tourbillon complication, is the perfect example of François-Paul Journe's mastery of horological traditions and his dedication to pushing the boundaries of modern timepieces. Originally produced between 1999 and 2003, the Tourbillon Souverain was the inaugural production wristwatch from Montres Journe. This example, crafted in 2003, represents the fourth and final generation of this iconic model. With around 300 pieces in existence, this rare Tourbillon Souverain has smaller dial screws, a flat remontoire cock, and deeper caseback engravings. Encased in platinum and featuring F.P. Journe's signature 'flat crown' with a rope-like pattern. We are thrilled to offer this exceptional Journe as a part of the Important Watches sale at #SothebysGeneva on 12 May. #Sothebys...
