We are huge fans of Audemars Piguet’s automatic perpetual calendar line of dress watches that were introduced in the late 1970s. This uncommon octagonal execution is 1980s perfection.As the watch industry was buckling under the weight of the quartz crisis, Audemars Piguet introduced the world’s thinnest automatic movement with a perpetual calendar complication. The resulting line of precious metal dress watches was in production from 1978 until the early 1990s and contained watches in different precious metals and with various dial options, often produced in small numbers.The significance of the automatic perpetual calendar line is twofold. For one, it signaled Audemars Piguet’s return to its roots as a maker of high complications. Quite something at a time when the watch industry was experiencing a life-threatening crisis. Second, these watches, along with the recently introduced Royal Oak, allowed the company to grow rapidly while most of its competitors struggled or went under.The QP line consists of mostly round watches. This early reference 25557 from 1983 is an exception. Unlike the typical dress watch—round, thin, and on a leather strap—this geometric beauty features a 35 mm octagonal (8-sided) 18k yellow-gold case with a round stepped bezel and sumptuous 18k yellow-gold integrated beads of rice bracelet.The matching champagne dial features a satin finish and four beautiful sunken sub-dials. The day, month, leap-year, and date are displayed in the three upper sub dials together with fierce blued sword hands, whereas the smaller dial at the 6 o’clock position houses a lovely moon phase indicator alongside the Audemars Piguet signature. The dial features a yellow-gold handset.An important standout of the QP line is the automatic movement. This movement was based on Jaeger LeCoultre’s legendary ultra-thin caliber 920 base movement, which was used, among others, in Audemars Piguet’s Royal Oak, Patek Philippe’s Nautilus and Vacheron Constantin’s 222. For the perpetual calendar line, Audemars Piguet reworked the base caliber to include a perpetual calendar complication and a 21k yellow-gold rotor.This exquisite 25557BA is in excellent condition and comes with an extract of the Audemars Piguet archives.
