Audemars Piguet Quantième Perpétuel Automatique 25657BA Box and Booklets
Widely renowned for the ever-iconic Royal Oak, Audemars Piguet’s prestigious history as one of the finest watchmakers on Earth is often overlooked in favor for the avant-garde design language they have recently begun to explore. Outside of their modern offerings, some of AP’s vintage timepieces exercise traditional watchmaking, stunning designs, and awe-inspiring craftsmanship, much like the Quantième Perpétuel Automatique ref. 25657 that we have here. Released in 1982 and discontinued in 1993, the ref. 25657 saw the production of 1821 units join its ranks with metals like 18k yellow gold, platinum, and others used over the years. Classically designed, the case features a traditional stepped bezel, short downturned lugs, and thin, elegant case proportions. With its symmetrical dial layout, the ref. 25657 features a perpetual calendar display made up of a day, date, and month subdials and a moon phase subdial at 6 o’clock for a satisfying aesthetic to round off its incredible design. Powered by the automatic cal. 2120/2800 movement, the ref. 25657 uses Jaeger LeCoultre’s iconic ultra-thin cal. 920 base movement, which AP shared with Vacheron Constantin, Patek Philippe, and others.
THE DIAL With its classical inspiration ringing out, the ref. 25657's symmetrical white dial with thin text in classical font pairs wonderfully with the 18k yellow gold hands and applied hour markers.
THE CASE Measuring just 7.55mm thick, the ref. 25657's svelte 36mm case is an astonishing achievement given the complexity of its movement for the time it was released.
