About this subject

The Patek Philippe Perpetual Calendar 5320, references 5320G (white gold) and 5320R (rose gold), was launched at Baselworld 2017, succeeding the iconic 5140. It represents the evolution of the perpetual calendar in the manufacture, combining aesthetic heritage from the 1950s with contemporary engineering. The dial displays three subdials: at 9 o'clock the day of the week, at 3 o'clock the month, and at 6 o'clock the date and moon phases. The central date hand is retrograde, and a small additional indicator shows the leap year. The movement is the Caliber 324 S Q, automatic, with 35 jewels, 48-hour power reserve, and Gyromax balance spring. The 40 mm case, with curved lugs and stepped bezel, is inspired by vintage models like the ref. 96. The crystal is sapphire, and the caseback reveals the movement adorned with the Patek Philippe seal. A technical curiosity: the perpetual calendar accounts for the secular year rule, automatically adjusting for 28-day Februaries except in years divisible by 400, meaning it will only need correction in the year 2100. The watch is an icon among collectors, with an estimated price around 100 thousand dollars. Its limited production and mechanical complexity make it a coveted object in the world of high horology.
