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.
WITH HIS OWN DIAL FACTORY, FRANÇOIS-PAUL JOURNE HAS NO OTHER LIMIT THAN THAT OF HIS IMAGINATION. HE HAS APPLIED HIS LABEL INVENIT ET FECIT ON EACH ONE, CERTIFYING AN AUTHENTIC CALIBRE, ENTIRELY INVENTED, PRODUCED AND ASSEMBLED IN THE WORKSHOPS OF HIS CENTRAL GENEVA MANUFACTURE.
THE BLACK LABEL COLLECTION IS AVAILABLE ONLY IN THE F.P.JOURNE BOUTIQUES AND ESPACES.
F.P.JOURNE PRESENTS THE NEW LUNE: A MORE VISIBLE READING OF THE TIME AND A DATE TWICE AS LARGE.
The F.P.JOURNE LUNE has a mechanical movement with automatic winding, manufactured in 18K rose Gold, built on the exclusive Calibre Octa 1300.3. It has made its mark as the first automatic movement with a power reserve sufficient to insure precision timekeeping for over five days or 120 h (EFFECTIVE power reserve: 160 h ± 10 h). It is wound unidirectionally by the exclusive off-centre F.P.JOURNE ROTOR IN 22K 5N Gold, using A SELF-LOCKING BALL BEARING SYSTEM for unequalled efficiency. EVERY INFINITESIMAL MOVEMENT OF THE WRIST IS THUS MAXIMALLY EXPLOITED FOR AN OPTIMISED WINDING OF THE WATCH. THE VARIABLE INERTIA BALANCE WHEEL ENSURES AN OPTIMUM YIELD THAT OFFERS AN IRREPROACHABLE STABILITY.
The F.P.JOURNE Lune’s two dials are made of 18K Gold. The off-centre dial, with Gold hour numerals surfaced with a diamond tool, is encircled by a polished Steel ring that is screwed to the second dial, one of the brand’s signatures. The main dial features a very large aperture for the date, a retrograde power reserve indication with a 120-hour scale as well as the moon phases.
The moonphase complication offers a link to ancient times, when the full moon was the only source of light during the night and instrumental in navigation and the rise of civilization. While today we no longer depend on moonlight for navigation, the moonphase remains one of the most poetic of all complications, giving an alternative perspective of the passage of time.
A SPECIFIC WHEEL TRAIN ALLOWS PRECISE MOON PHASE INDICATIONS. ADJUSTING THE INDICATIONS IS DONE VIA THE CROWN, WHICH MAKES IT VERY EASY TO USE.
The Lune was awarded the Prize “Best Men’s Watch” at the Geneva Grand Prix d’Horlogerie in 2003.
A horological ideal
“The construction of the Octa calibre has less powerful ties with horological history than do the constant-force device or resonance models, but it symbolises an horological ideal of giving timekeepers the highest possible degree of precision and autonomy!
One can indeed note the fact that if church clocks are placed so high, in addition to enhancing visibility, it was mostly because it often took an entire month for the driving-weights to drop the length of their cords. Numerous systems were invented to increase the operating duration of timekeeping devices, meeting with various degrees of success. Given the small volume of a wristwatch, the size of the mainspring was automatically limited. Watchmakers therefore discovered the trick of adding an extra wheel to the customary geartrain in order to extend the duration of its development. Unfortunately, actually using this system, even with a stronger spring, led them to observe that the level of energy actually reaching the balance remained low. To compensate for this, they fitted a smaller balance using less energy, but which was also less stable. It is therefore not unusual to find that some watches able to run for several days display an extremely unpredictable level of precision.
This challenge was a powerful source of motivation! I then imagined that the best and the most obvious means of extending the running duration would be to extend the capacity of the spring development. The difficulty lay in integrating it on the same level as the gear-train and the escapement, given its stability: 1 metre and 1 millimetre thick. Thanks to the low torque of this spring, I could achieve extremely fast automatic winding (one and a half hours on a Chappuis cyclotest for over 5 days’ running).
Once the challenge of autonomy was thus successfully met with this automatic winding calibre, I knuckled down to the second challenge of managing to insert various complications into that same movement: power reserve with large date display, fly-back chronograph with large date display, retrograde annual calendar, etc… and of doing so while maintaining an identical size for all models.
Three years of research and development were required before this automatic winding movement that is unique in the world could be presented to the public.”
