Nicknamed by enthusiasts the “APQP” (for Audemars Piguet Quantieme Perpetuel),the reference 5548 was developed during the height of the quartz crisis. The APQP is credited with helping Audemars Piguet survive the quartz crisis by showcasing the enduring appeal and technical prowess of mechanical watches. - Produced from 1982 until 1993, the present successor ref. 25657 can be found in both C and D series. According to Audemars Piguet, a total of 1,821 examples were produced throughout the years. Mostly cased in yellow gold with 1,309 pieces, there are a total of 362 pink gold examples ever made. - Characterized by its solid snapped caseback, sucken sub-dials and “Swiss Made” inscription, the reference houses the ultra-thin AP 2120/2800 automatic movement. Based on the legendary Jaeger-LeCoultre’s 920, it was the thinnest automatic movement created at the time, and despite the perpetual calendar module stacked on top, it still remains one of the thinnest calendar movements at 3.9 mm thick. - This example’s blend of elegance, wearability, and historical importance makes it a cornerstone in any enthusiast’s collection, a true testament to Audemars Piguet’s dedication to mechanical innovation during challenging times.
