The ninth model in the Octa collection, the F.P.Journe Quantième Perpétuel with instantaneous jump, provides a distinct visual style compared to traditional perpetual calendars, focusing on superior readability via a sparse dial with generous apertures: two slots for the day and month, and a large date shown in two windows, a trademark of F.P.Journe. An innovative system powers the instantaneous jump, accumulating energy to discharge it at once when the date, day, or month shifts, while slowing the mechanism at the conclusion of the process.
