While some may think the construction of the Octa calibre has less powerful ties to the history of horology than the constantforce device or resonance phenomenon, it in fact symbolizes an important historical horological ideal: giving timepieces the highest
possible degree of precision and autonomy.
It is commonly observed that church clocks are set so high in towers to enhance their visibility, however this positioning is
mostly because it often allows almost an entire month for the driving weights to drop the length of their cords. Over time, numerous
systems have been invented to increase the running time of a timekeeper’s device but only with limited success. Given the restricted
dimensions of a wristwatch, the size of the mainspring was immediately limited. Watchmakers then discovered the trick of adding an
extra wheel to the customary gear train in order to extend the length of its development. Unfortunately, using this system only led them
to observe that the level of energy actually reaching the balance remained poor. To compensate, they fitted a smaller balance consuming
less energy but this also resulted in lost stability. Therefore, it’s not unusual to find watches that run for several days displaying an extremely unpredictable level of accuracy.
This historical challenge was a powerful source of motivation for me. I then imagined that the best and most obvious solution to lengthen the running time would be to increase the capacity of the spring development. Given its stability (1 metre long and
1 millimetre thick), the challenge was to integrate it on the same level as the gear train and escapement. Thanks to the low torque of
this spring, I could achieve extremely fast automatic winding (one and a half hour on a Chappuis cyclotest for over 5 days running).
Once the challenge of autonomy was successfully met with this automatic winding calibre, I began 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, UTC, etc… and doing so while maintaining an identical size for all models in the Octa
collection. Three years of research and development were required before this one of a kind automatic calibre could be presented
to the public.

Preface
Calibre Octa
An Horological Ideal_
22
Created in the 19th Century, GMT, Greenwich Mean Time, originally referred to mean solar time at the Royal Observatory in Greenwich, London. Already used by the British navy to calculate their
longitude position from the Greenwich meridian, it was introduced
in the United Kingdom by the Railway Clearing House in 1847. It
was then legally adopted as official time throughout Great Britain in
1880, and then in the entire world for the major part of the 20th
Century, before being replaced in 1972 by UTC, Universal Time
Coordinate.
Chronology
Octa UTC
Coordinated Universal Time_

GMT is usually used in the watchmaking world to designate watches with a second time zone. GMT is based on terrestrial rotation, while UTC on atomic international time therefore the two time measurements are close but not the same. Unlike GMT, UTC
offers the current view of time zone division directly linked to the real rotation of the earth, and less variable.
F.P. Journe innovates once again with the presentation of the Octa UTC ®, patented system that faithfully takes us back to the
modern standards of determining time zones in full hours. Mechanically it indicates the different time periods linked with the earth’s
geographical positions, indicating summer and winter hours.
On the dial, the main hours are indicated by the blue hands, and linked to the calendar indicating the main geographical time.
The red gold hand indicates the time zones on 24 hours, represented by the earth’s 24 time zones.
Always taking into account the notes and observations concerning his watches, François-Paul Journe states: “I realized that
one of my friend’s Octa was never completely wound because he works on a computer and his hand doesn’t move enough.”
From this observation he created the new Octa caliber (1300.3) that uses the slightest movement to automatically wind the
watch. With talent, the watchmaker turns the problem around, and creates a new off centered rotor heavier in 22K gold, that winds
in only one direction with a self-locking ball bearing system. The ceramic balls allow the rotor to move in one direction and block it
in the other. This way, every infinitesimal movement is maximally exploited for an optimized winding of the watch.
The new calibre retains the characteristics of the classic Octa with a five day power reserve (120h) and a variable inertia balance wheel for an optimum yield that offers each model of the Octa line an irreproachable stability. The Octa collection is conceived
for all lifestyles, from the more peaceful to the most active!

Setting summer time.
If you live in Paris, in relation to Tokyo, you are at -8 from Tokyo time. While Paris moves into
summer daylight saving time, there is no hour change in Tokyo. Paris will then be at -7 from
Tokyo. Positioning the Japan timezone on +1 will indicate the corresponding time automatically.
-8 +1 = -7
