5320G Grand Complications 40mm Shiny Chocolate Brown Alligator Leather Strap Rose-Gilt Opaline Dial White Gold Bezel

The Reference 5320 Patek Philippe perpetual calendar model bears a testament to the brand's commitment to visual balance and legibility. Created in 2017. it features a white gold case with a cream-lacquered dial. and was recently reinterpreted in a gilded opaline rose gold dial version. This classic design replicates the type found in Patek Philippe perpetual calendar watches since 1941. with a 12 o'clock day/month aperture. a 6 o'clock date window and moon-phase indicator. and two additional round apertures between 7 and 8 o'clock and 4 and 5 o'clock to assist with the calendar display's adjustments. Moreover. this design is extremely accurate. needing only a one-day adjustment every 122 years.
