Technical description


(1) 22K Gold rotor with uni-directional winding
(2) Large capacity mainspring barrel
(3) Precision-adjustment weights
(4) Full-size free-sprung chronometer balance

Watches with long power reserves have hitherto been handicapped by small balances which are susceptible to shocks and disturbances. The Octa's compact construction allows a large (10.1 mm) balance to be fitted, giving greater inertia and stability. The free-sprung chronometer balance is adjusted by five turning weights that vibrate at a steady 21'600 times an hour.

Fully wound, the Octa delivers chronometric precision for 120 hours. The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.

About

THIS MODEL WAS PRODUCED BETWEEN 2006 AND 2010.

AN EXCLUSIVE COLLECTION AVAILABLE ONLY FOR F.P.JOURNE WATCH OWNERS.

WITH A LIMITED PRODUCTION OF ABOUT 1000 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.

THE BLACK LABEL COLLECTION IS AVAILABLE ONLY IN THE F.P.JOURNE BOUTIQUES AND ESPACES.

WORLD PREMIERE:
FIRST MECHANICAL MOVEMENT WITH AUTOMATIC WINDING AND A POWER RESERVE OF OVER 120 HOURS.

THE ROBUST, MULTI-PURPOSE OCTA IS F.P. JOURNE'S MOST HIGHLY EVOLVED CONSTRUCTION. WITH DIFFERENT COMPLICATED MECHANISMS BUILT INTO MOVEMENT, THE OCTA FIVE-DAY AUTOMATICS ALWAYS MEASURE 30 MM X 5.5 MM. IT'S RARE TO FIND A WATCHMAKER WITH A SPATIAL VISION TO IMAGINE A SINGLE COMPLEX CHASSIS THAT INTEGRATES VERY DIFFERENT MECHANISMS WITHOUT CHANGING ITS SIZE. IT IS ALSO THE FIRST AUTOMATIC MOVEMENT WITH A POWER RESERVE THAT MAINTAINS PRECISION TIMEKEEPING FOR FIVE DAYS (120 HOURS) OFF THE WRIST.

Testimony
Calibre OCTA

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.”

    Technical description


    (1) 22K Gold rotor with uni-directional winding
    (2) Large capacity mainspring barrel
    (3) Precision-adjustment weights
    (4) Full-size free-sprung chronometer balance

    Watches with long power reserves have hitherto been handicapped by small balances which are susceptible to shocks and disturbances. The Octa's compact construction allows a large (10.1 mm) balance to be fitted, giving greater inertia and stability. The free-sprung chronometer balance is adjusted by five turning weights that vibrate at a steady 21'600 times an hour.

    Fully wound, the Octa delivers chronometric precision for 120 hours. The meter-long mainspring supplies an average 850gr of torque, limiting the loss in balance amplitude to 25% over the five-day period. Beyond that time, the watch will continue to go for another day or two, but the amplitude-loss no longer guarantees precision timekeeping.
