FP Journe Octa Perpetuelle

OCTA PERPÉTUELLE

The OCTA collection unveils the Perpetual Calendar F.P.Journe Anniversary Watch in Limited Edition of 99 pieces 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.
