F. P. Journe Tourbillon Souverain
Origins of the Tourbillon
The Tourbillon complication holds a special place in the history of F. P. Journe. The likes of both George Daniels and Abraham Louis Bréguet inspired F. P. Journe to create his own tourbillon, it took five arduous years to complete his first tourbillon pocket watch, signed F. P. Journe – A Paris. Today, this pocket watch marks one of the most important milestones in François-Paul’s career, achieving to build a tourbillon from scratch was simply uncommon back then. In 1999, after having established Montres Journe SA, the brand F. P. Journe presented their first wristwatch which was a Tourbillon Souverain a Remontoir d’egalité. A partner of the brand, Gino, vividly recollects the warm reception that the Tourbillon generated …
“It was simply amazing, everyone found it beautiful, it was original, following the rules of Bréguet and it was a question of accuracy … the remontoir d’egalité was unique the tourbillon would work even if you only had 30 minutes of power reserve. It was quite a success”
This 40mm 18-carat rose gold F. P. Journe Tourbillon Souverain (TN) features a textured ‘grainy’ rose gold dial, in addition, the separate silvery guilloché dial for the hours, minutes and seconds would be best described as ‘matt’ white. The dial remains in immaculate condition, showing virtually no signs of oxidation. Interestingly, an 18-carat rose gold case paired with an 18-carat rose gold dial is not necessarily common. It is thought that these examples are usually the rarest across all F. P. Journe references.
The distinction between the manually wound and automatic movements can be divided into the following: Octa (automatic) and Souverain (manually wound). The Tourbillon Souvain is powered by caliber 1498 naturally, the movement is Francois Paul’s unique creation. The power reserve of the entire souverain collection is based on antique marine chronometers, the power reserve indicator shows the number of hours elapsed since the watch was last wound. Therefore, when fully wound the indicator reads “0” as it has been zero hours since last wound. In his quest for chronometric performance, François-Paul invented his own interpretation of a constant force mechanism named the remontoir d’egalité, the use of the remontoire – a constant force device – can be compared to a dam that controls the flow of water and provides constant energy to the blades of a turbine. In effect, the remontoire regulates the power to the escapement to attain greater stability in rate. The adjustable inertia weights make it possible to optimize the amplitude of oscillation; the four-armed balance beats at a frequency of 21’600 v/h.
