1990 Audemars Piguet Quantième Perpetual Calendar 18k yellow Gold Mother of Pearl Dial 25657BA with Box and papers

A very rare and unpolished 18k yellow gold Audemars Piguet Quantième Perpetual Calendar reference 25657BA, dating from 1990. This 36mm masterpiece boasts an extremely rare "Mother of Pearl" dial. This example presents cracks inside both sub-dials. 

The perpetual calendar complication is seamlessly integrated into the dial, showcasing the moon phase, day, date and month indications with classic elegance. The unpolished case retains its original sharp lines and factory finish, offering a glimpse into the watchmaker’s artistry from this era. Renowned for its iridescent beauty, mother-of-pearl is a natural material derived from the inner shell of mollusks. Each piece is unique, with subtle color variations, texture and shimmer, ensuring no two dials are alike.

The combination of the no-lume "Mother of Pearl" dial, untouched case, and Audemars Piguet's technical brilliance makes this timepiece a rare and highly collectible example of vintage haute horology. A timeless creation that embodies understated luxury and technical mastery.
