F.P.Journe Tourbillon Souverain with Régence Circulaire Hand-Engraved Dial

Luxury watch manufacture F.P.Journe presents a special edition Tourbillon Souverain watch featuring the exclusive Régence Circulaire dial. Made in a limited edition of only 20 pieces, this timepiece takes us to the golden age of time measurement. The Régence Circulaire motif, which pays homage to the clockmakers and artisans of the 18th century, was inspired by geometrical motifs of the Regency period.

The Tourbillon Souverain with the remontoire or constant force device system, which the brand values since 1983 for its timekeeping performances, is enriched with the addition of an independent dead-beat second. This complication, representing a unique feature on a contemporary wristwatch, provides a more accurate read-off of time. The French term for “dead second” (seconde morte) or “dead-beat seconds”, stems from the fact that the hand remains motionless (“dead”) for as long as the second has not actually elapsed. The hand thus indicates the second once it has actually gone past.

The Tourbillon Souverain is still the most accurate on the market today. This exceptional mechanism in 18K rose Gold, specificity of the brand, reveals its technical performance through the transparent sapphire crystal case-back.

Dressed in a 40mm case in 18K red Gold, the Tourbillon Souverain with Régence Circulaire hand-engraved dial is available exclusively in the F.P.Journe Boutiques and Espaces.
