Technical description

The remontoire (constant force device) comprises a secondary wheel (1) assembled on a lever (2), which swivels concentrically to the cage (3) of the tourbillon. This lever stops the principal wheel which carries the second hand (4) and transmits the energy of the barrel, whereas the auxiliary spring (5) (or equalizing spring) gives its energy to the escapement. (6) This then allows the secondary wheel to release once per second, and with repetition, the auxiliary spring is re-fuelled by the principal wheel.

What is a remontoire ?
In the Toubillon Souverain, 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.

About
THIS MODEL WAS PRODUCED IN 2016.

IN 1999, FRANÇOIS-PAUL JOURNE LAUNCHED HIS F.P.JOURNE -INVENIT ET FECIT- BRAND WITH THE TOURBILLON SOUVERAIN, THE FIRST MODEL IN THE SOUVERAINE COLLECTION AND THE ONLY TOURBILLON WRISTWATCH WITH REMONTOIRE (CONSTANT FORCE DEVICE).

THIS INVENIT ET FECIT- MECHANISM, INVENTED AND MADE BY FRANÇOIS-PAUL JOURNE, PROVIDES UNIQUE TIMEKEEPING PERFORMANCE IN A TOURBILLON WHICH IS STILL THE MOST ACCURATE ON THE MARKET.

in 2000, F.j.JOURNE PRESENTED THE TOURBILLON SOUVERAIN WITH LABYRINTHE MOTIF ENGRAVED ON THE DIAL AT the INTERNATIONAL JEWELLERY & WATCH EXHIBITION IN BAHRAIN. A FEW TOURBILLON SOUVERAIN WITH LABYRINTHE AND RÉGENCE LOSANGE ENGRAVED DIALS WERE PRODUCED IN 2000 AND 2001.

in 2004, dRIVEN BY HIS THIRST FOR TIMEKEEPING RESEARCH AND HIS CREATIVE NEEDS, FRANÇOIS-PAUL JOURNE PRESENTed THE NEW GENERATION OF TOURBILLON SOUVERAIN, WITH REMONTOIRE AND DEAD BEAT SECONDS. THIS MODEL REPLACEd THE EXISTING TOURBILLON SOUVERAIN WITH REMONTOIRE that became a COLLECTOR'S timepiece. as only aBOUT A HUNDRED were produced give this watch an even more SOUGHT-AFTER STATUS.

THE TOURBILLON SOUVERAIN WITH REMONTOIRE AND DEAD BEAT SECONDS IS ENDOWED WITH THE CHARACTERISTICS AND TECHNICAL DEMANDS INHERENT TO CREATIONS BY F.P. JOURNE - INVENIT ET FECIT -. ITS MECHANISM USES THE REMONTOIRE OR CONSTANT FORCE DEVICE, WHICH THE BRAND VALUES FOR ITS TIMEKEEPING PERFORMANCES, AND HAS NOW BEEN ENRICHED WITH AN INDEPENDENT 'DEAD BEAT SECONDS' SYSTEM. THIS COMPLICATION, REPRESENTING A UNIQUE FEATURE ON A CONTEMPORARY WRISTWATCH, PROVIDES FOR A MORE ACCURATE READ OF PRECISE TIME. THE FRENCH TERM FOR "INDEPENDENT SECONDS", CALLED "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 ONLY AFTER IT HAS ACTUALLY PAST.

THIS EXCEPTIONAL MECHANISM IS HOUSED IN AN EQUALLY NOBLE 40 MM CASE IN 18 CARAT 6N GOLD. THE BEAUTY AND SOPHISTICATION OF THIS TECHNICAL AND AESTHETIC FEAT ARE REVEALED THROUGH THE TRANSPARENT SAPPHIRE CRYSTAL CASE-BACK.

F.P.JOURNE PROPOSES THE TOURBILLON SOUVERAIN WITH AN EXCLUSIVE RÉGENCE CIRCULAIRE ENGRAVED DIAL. IT TAKES TWO DAYS TO A SWISS ARTISAN BASED IN GENEVA TO ENGRAVE THIS ARTWORK by hand.

THE WHITE GOLD DIAL FEATURES THE DISTINCTIVE IDENTITY OF THE F.P.JOURNE CHRONOMETERS WITH STEEL CIRCLES SCREWED ON THE FACE (A PATENTED FEATURE). HOURS, MINUTES AND SECONDS’ DIALS ARE MADE IN SILVER "GUILLOCHÉ". THE 42-HOUR POWER RESERVE INDICATION AT 12 O'CLOCK PERFECTLY COUNTER-BALANCES THE INDEPENDENT SECONDS DISPLAY AT 6 O'CLOCK.

AVAILABLE AT F.P.JOURNE BOUTIQUES AND ESPACES ONLY.
