Audemars Piguet Royal Oak Perpetual Calendar
The Royal Oak in its most complete form. Audemars Piguet's perpetual calendar follows the day, date, month, moon phase and leap year without correction until the year 2100, all within the octagonal case that changed fine watchmaking in 1972. This reference carries it in rose gold.
