The new F.P.Journe Invenit et Fecit Quantième Perpétuel with instantaneous jump is the ninth creation within the Octa line and it certainly presents a distinctive aesthetic compared to other existing perpetual calendars. It offers perfect readability through an uncluttered dial with large apertures: two for the day and month calendar, and a large date in two windows, a specificity of F.P.Journe watches.
The F.P.Journe Quantième Perpétuel is very easy to adjust. Corrections are made using the three-position crown, except for the rapid correction of months, which is carried out by a protected and hidden corrector lever beneath the lug at 1 o’clock, thus facilitating the adjustment over four years without any specific tool.
The automatic winding movement of the Quantième Perpétuel is manufactured in 18K rose gold, like that of all F.P.Journe precision chronometers. It also features the exclusive off-centre F.P.Journe rotor in 22K red gold that offers optimal winding of the watch for an effective power reserve for over 120 effective hours.
The Quantième Perpétuel is available in Platinum or in 18K red Gold, in 40 or 42 mm diameter, with red or white Gold dial fixed by a steel circle with a silver chapter ring. Below the pictures of the platinum and red gold models with inverted dial colours.
