In 1986, Audemars Piguet quietly reshaped its modern chronograph identity with the introduction of reference 25644. At a time when the integrated automatic chronograph was still a frontier, the Maison combined self-winding, chronograph, and date functions, a confident technical statement in classical proportions. Later referred to in Italian catalogues as the “Huitième,” it marked a quietly bold new chapter. The present offer brings together not one, but four expressions of that chapter, sold as a single, indivisible lot. Four examples of reference 25644 in four distinct metals: pink gold, yellow gold, stainless steel, and the striking combination of tantalum and pink gold. The lot is also composed by the crowning piece: a Huitième Perpetual Calendar Chronograph reference 25695 in pink gold from 1993. If the 25644 represents Audemars Piguet entering the automatic chronograph era with date, the 25695 elevates the narrative to high complication, uniting perpetual calendar mastery with chronographic performance in one harmonious composition. To encounter even one very nice Huitième is not so uncommon. To assemble all principal metals, including tantalum, a material both technically challenging and visually magnetic, is extraordinary. To add the perpetual calendar chronograph, and to present all five together, transforms rarity into event. Accompanied by Extracts from the Archives confirming their production, this ensemble is further accompanied by service documentation pertaining to the four Huitième reference 25644 examples.
