Representing the ninth addition to the Octa series, this F.P.Journe Quantième Perpétuel features an instantaneous jump and a unique design that stands apart from standard perpetual calendars by ensuring excellent legibility through a minimalist dial with wide openings: two for the day and month, and a hallmark F.P.Journe large date display. The instantaneous transition is powered by a specialized mechanism that builds up energy for a sudden release during calendar changes, decelerating the motion at the end of the cycle.
