Reference 5320G
Ref. 5320 was launched in 2017 and is produced exclusively in white gold, featuring a cream-lacquered dial. The twin in-line day/month aperture at 12 o’clock and the moon-phase aperture at 6’oclock is characteristic of Patek Philippe perpetual calendar watches since 1941. The moon phase requires a one-day correction once every 122 years and the watch features two practical round apertures (one for day/night indication between 7 and 8 o’clock) and another for the leap-year cycle (4-5 o’clock).
