Press release
Unlike perpetual calendars that are often difficult to adjust, the F.P. Journe Quantième Perpétuel is very easy to use. All 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 months with 28, 29, 30 and 31 days are automatically taken into account and leap years recognised with years 1, 2 and 3 shown in black; 4 for the leap year shown in red in the centre of the dial under the hour and minute hands.
The automatic winding movement of the Quantième Perpétuel by F.P. Journe Invenit et Fecit is manufactured in 18K rose Gold, like that of all the brand's precision chronmometers. It is constructed on the basis of the exclusive Octa calibre 1300.3, with an identical calibre leaving room to insert all the complications of the Octa line. 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 with retrograde indication for over 120 effective hours. It winds the movement in only one direction with an autoblocant ball bearing system (self-blocking). Every infinitesimal movement of the wrist is thus maximally exploited for an optimised winding of the watch.
With a total and very limited production of nearly 900 pieces per year, the custom of F.P. Journe is to stop producing an existing calibre when creating a new model. Therefore, the Quantième Perpétuel replaces the Octa Calendrier with annual calendar, which will cease production in 2013 thus becoming a collector's piece.
The Quantième Perpétuel is available in Platinum or in 18K red Gold, in 40 or 42 mm diameter. The red or white Gold dial is fixed by a steel circle with a silver chapter ring.
