Audemars Piguet Quantième Perpetual Edward Piguet silver Dial ref 25682BA in 18 k yellow gold, 1980s

Dealer description — Bulang & Sons

In 1875, Jules Louis Audemars and Edward Auguste Piguet founded the Swiss watchmaking house Audemars Piguet in Le Brassus, nestled in the Vallée de Joux. A pioneer in haute horlogerie, the brand made history in 1955 by releasing its first series of perpetual calendar wristwatches with a leap year indication. The Quantième Perpétuel 25682 belongs to the Edward Piguet collection—named in honor of one of the brand’s founders. Its design draws inspiration from a distinctive rectangular “tank-style” watch created by Audemars Piguet in the mid-1920s. This QP 25682BA features a contemporary 45mm by 27mm rectangular case that delivers a refined and unmistakable wrist presence. Its elongated lugs extend in smooth, continuous lines, adding to the watch’s architectural elegance. From the bezel to the gently contoured lugs, the case finishing is thoughtfully executed, offering a soft sophistication and a more approachable aesthetic. The dial maintains the traditional perpetual calendar layout, thoughtfully reimagined to suit the rectangular format. The date appears at 3 o’clock in a recessed sub-dial that adds depth to the smooth silver surface. Opposite, the day of the week sits at 9 o’clock, with the month at 12, and a moon phase display at 6—complete with a moon age scale above it. Each sub-dial features fine concentric graining, creating visual texture and elevating the watch’s sense of complexity and charm. Painted Breguet numerals add a nostalgic nod to classic perpetual calendars, infusing the silver dial with vintage character—an increasingly rare and desirable detail among collectors. Elegant leaf-shaped hands mark the hours and minutes, while the sub-dials are accented with blued steel hands for a subtle yet striking contrast. Powering the 25682 is the manual-winding calibre 2003 with a 2805 QP perpetual calendar module—an ultra-thin movement based on a legendary Jaeger-LeCoultre ébauche. The watch has been fully serviced by our watchmaker. It is paired with a Bulang and Sons leather strap, which we believe is a perfect match for this timeless piece. We think these represent true value in today’s market. Don’t hesitate to reach out!
