The secrets of the Perpetual Calendar Ref. 5320G

After watching this video presentation, Patek Philippe's latest Perpetual Calendar won't have any secrets for you.

Patek Philippe's Ref. 5320G is a new perpetual calendar that has literally been crafted for eternity. It automatically indicates months with 28, 30, and 31 days and, every four years, also recognizes the 29th of February as a leap day. It stands out with a timelessly sleek design, affording a glimpse into the past, present, and future at the same time. Rarely has a perpetual calendar demonstrated its function so aptly. In fact, it is easy to forget that in 2100, a secular year according to the Gregorian calendar, the date display must be corrected by hand.
