The Octa Quantième Perpétuel was first introduced in 2012 in both 40mm and 42mm cases and encased in either platinum or pink gold. In transition between the Calandrier model and the present Perpétuel wristwatch was the Octa Perpetuelle made for the Tokyo Boutique in a limited series of 99 pieces whose layout was like that of the Calandrier, but with a perpetual calendar complication rather than annual calendar.

The present Quantième Perpétual draws design inspiration from the Octa Divine with a quatrefoil layout, however rather than Journe’s typical offset display, the Perpétual features the day, date, month, and power reserve in a quadrants, with the leap year indicator subtly displayed around the center post. Two stand-out features of the Quantième Perpétuel exemplify the genius of François-Paul Journe: simultaneous, instantaneous jumping of all calendar indications – the date, day, and month – at midnight, and the ability to simply adjust each calendar indication without the use of any tool. The perpetual calendar is adjusted through the quick-set mechanism in the crown except for the month, which is changed through a small lever located under the top right lug.

The present lot is offered with all its original accessories with the F. P. Journe International Guarantee dated March 28, 2022. The watch is in near new condition with hardly any signs of wear. The Quantième Perpétuel is a technically impressive timepiece with a timeless understated elegance.
