THE F.P.JOURNE CHRONOMÈTRE À RÉSONANCE IS THE ONLY WRISTWATCH IN THE WORLD THAT UTILIZES THE PHYSICAL NATURAL RESONANCE WITHOUT ANY MECHANICAL TRANSMISSION PHENOMENON, PREVIOUSLY KNOWN AS DOUBLE PENDULUM OR DOUBLE BALANCE. MOVING TOWARDS MORE PRECISION, ALWAYS! THE NEW CHRONOMÈTRE À RÉSONANCE HAS ONLY ONE SINGLE BARREL SPRING TO PROVIDE POWER FOR THE TWO MOVEMENTS. A DIFFERENTIAL PLACED ON THE FIRST WHEEL, VISIBLE IN THE CENTRE OF THE DIAL, TRANSMITS, INDEPENDENTLY, THE ENERGY OF THE BARREL SPRING TOWARDS THE TWO SECONDARY GEAR TRAINS. EACH SECONDARY GEAR TRAIN IS EQUIPPED WITH A REMONTOIR D’EGALITÉ OF A FREQUENCY OF 1 SECOND. WORKING IN SUCH A WAY, THE FORCE RECEIVED BY THE ESCAPEMENTS REMAINS LINEAR AND ASSURES ISOCHRONISM THROUGHOUT 28 HOURS. THE CHRONOMÈTRE À RÉSONANCE FEATURES A REDESIGNED CASE WITH A CROWN NOW PLACED AT 2 O’CLOCK EASING THE WINDING OF THE WATCH IN POSITION 0 AND THE TIME SETTING IN POSITION 2, CLOCKWISE FOR THE LEFT DIAL AND ANTI-CLOCKWISE FOR THE RIGHT DIAL. THE PULLING OF THE CROWN AT 4 O’CLOCK SIMULTANEOUSLY RESETS BOTH SECONDS. ON THE MOVEMENT SIDE, 2 «REMONTOIRS D’ÉGALITÉS» (CONSTANT-FORCE DEVICE) PROVIDE A LINEAR FORCE TO EACH OF THE TWO BALANCE SPRINGS TO REMAIN ISOCHRONOUS DURING 28 HOURS.
