Audemars Piguet Quantième Perpétuel (1990)

About this reference

The Audemars Piguet Quantième Perpétuel reference 25548BA was produced between approximately 1982 and the early 1990s, representing a pivotal era for the brand’s ultra-thin complications. This 18k yellow gold model measures 36mm in diameter and is powered by the self-winding caliber 2120/2800, which is based on the Jaeger-LeCoultre 920 movement. Collectors value this reference for its historical significance in popularizing the perpetual calendar during the post-quartz crisis recovery and for its classic four-subdial layout without a leap year indicator. The case features a stepped bezel and short lugs, characteristic of the Quantième Perpétuel line's early design language. On the secondary market, this reference typically trades between $35,000 and $55,000 depending on condition and the presence of original paperwork. A notable production detail is that early examples often feature "Audemars Piguet" branding without the "Automatic" text on the dial, a variation sought by vintage enthusiasts.
