The latest addition to the Octa collection is the F.P.Journe Quantième Perpétuel with an instant jump feature. Its unique design stands out from other perpetual calendars, boasting a clean and easy-to-read dial with large openings for the day, month, and date. This is a trademark of F.P.Journe watches. The instant jump is made even more impressive by the brand's clever energy accumulation system, which allows for a quick change of date, day, or month, followed by a gradual slowdown.
