AN EXCLUSIVE COLLECTION AVAILABLE ONLY FOR F.P.JOURNE WATCH OWNERS. WITH A LIMITED PRODUCTION OF ABOUT 900 TIMEPIECES PER YEAR, F.P.JOURNE WANTED TO OFFER AN EVEN MORE EXCLUSIVE TIMEKEEPER THAT WOULD BE AVAILABLE ONLY FOR OWNERS OF AN F.P.JOURNE WATCH. WITH A CASE MADE IN PLATINUM, THE MOST PRECIOUS METAL, F.P.JOURNE HAS CREATED A DISTINGUISHED BLACK DIAL THAT PERSONALIZES EVEN FURTHER THE ELEGANCE OF THE BRAND WATCHES. THE BLACK LABEL COLLECTION WAS BORN. HE BLACK LABEL COLLECTION IS AVAILABLE ONLY IN THE F.P.JOURNE BOUTIQUES AND ESPACES. THE F.P.JOURNE CHRONOMÈTRE À RÉSONANCE CELEBRATES ITS 20TH ANNIVERSARY.

SINCE THEN, FRANÇOIS-PAUL JOURNE PRESENTED HIS FIRST RÉSONANCE WRISTWATCH IN 2000, IT WAS BAPTIZED RÉSONANCE UNDER THE PATENTED BRAND NAME RÉSONANCE®.
