Two fascinating, highly regarded complications that have appealed to admirers of fine watchmaking and astronomy since their initial development, the perpetual calendar and moon phase indicator are presented here by Audemars Piguet in a strikingly attractive design with a special touch of luxurious radiance. Indicating day, date and combined months and leap year in sub-dials positioned at nine, three and 12 o?clock respectively, the perpetual calendar function accompanies central hours, minutes and seconds on the ?Grande Tapisserie? blue dial with luminescent coating on Royal Oak hands, while the moon phase indicator, requiring correction every 125 years and 317 days, is nested at six o?clock.

Ensuring 20m water resistance and mounted onto 18K rose gold bracelet with AP deployment clasp, the 41mm case is also made of 18K rose gold and features glareproofed sapphire crystal on the front.
