F. P. Journe Octa Quantieme Perpetual Platinum Gray Dial 42MM

The F.P. Journe Octa Quantième Perpétüel in 42 mm is a modern classic, first introduced circa 2012 with deliveries commencing around 2015. It unites technical sophistication with elegant legibility, featuring a perpetual calendar with instantaneous jump, large apertures for day, month and date, a centrally mounted leap‑year indicator, and a retrograde power‑reserve display — driven by the automatic caliber FPJ 1300‑3 crafted in 18K rose gold. The slim 10.8 mm platinum case, restrained bezel and articulated lugs deliver a supremely wearable profile despite its complexity. The off‑centre 22K gold guilloche rotor ensures a remarkable 120‑hour autonomy, while the perpetual mechanism corrects effortlessly via crown and discreet under‑lug pusher. Limited to a production of around 900 pieces per year, this reference carries both rarity and movement refinement, placing it among the most desirable perpetual calendars for seasoned collectors seeking a blend of innovation, aesthetic balance, and in‑house pedigree.
