F.P.Journe OCTA PERPÉTUELLE Titanium Limited Edition

In 2001, F.P.Journe presented the OCTA collection composed of mechanical wristwatches with automatic winding featuring an exceptional power reserve of 5 days (120h), all of which with the same case thickness regardless of the complication. It was a technical prowess to insert all the complications of the OCTA line in the same space.

The OCTA PERPÉTUELLE, 8th creation of the collection rightfully bears its name and enriches the collection of the automatic winding calibre signed F.P. Journe –Invenit et Fecit. The new, well achieved prowess was in inserting this time a perpetual calendar, in the same space. Anniversary timekeeper, the new OCTA PERPÉTUELLE in Titanium celebrates the Boutiques F.P.Journe’s network around the world with the 5th anniversary of the first Boutique F.P.Journe in Tokyo.

Produced in Limited Series of 99, its case is exceptionally manufactured in Titanium for the occasion and is completed with a Ruthenium on Gold dial. The automatic winding movement is manufactured in 18K rose gold, like that of all F.P.Journe –Invenit et Fecit watch creations. It is constructed on the exclusive OCTA calibre 1300.3, with retrograde date indication, an aperture for the day, another for the month, with indication of the leap year within the month of February. The passing of the months of 28, 29, 30 and 31 days is done automatically with recognition of the leap year (indicated).

The OCTA PERPÉTUELLE also features the exclusive off-centre F.P.Journe rotor that winds in only one direction with an autoblocant ball bearing system (self-blocking). The ceramic balls allow the rotor to move in one direction and blocks it in the other. In this way, every infinitesimal movement is maximally exploited for an optimized winding of the watch.The secured pusher at 8 o’clock is intended for the manual passing of the months during the initial setting. This exclusive pusher avoids any possibility of accidental activating, allowing a use without any specific tools.
