Audemars Piguet Quantième Perpetuel 25717PT, Platinum

Inspired From the Past

In 1875, Jules Louis Audemars and Edward Auguste Piguet founded the Swiss watch manufacturing company Audemars Piguet in Le Brassus, Vallée de Joux. In 1955, the brand began production of its first series of perpetual calendar wristwatches to feature a leap year indication. A specialist in the manufacture of complications since it was established, Audemars Piguet continued to produce a variety of high-quality perpetual calendars throughout the late 1970s to the early 2000s, considered some of the most impressive of the modern era. 

This Quantième Perpetuel 25717PT is one of only 70 examples made to celebrate the 700th anniversary of the Swiss Confederation, as confirmed by the accompanying Archive Extract. It also features a commemorative engraving on the caseback. 

A Classic Design

This Quantième Perpetuel 25717PT is classically sized at 33mm and has a distinctive stepped case. The teardrop lugs flank the case on either side, complimenting the convex bezel portion. On the reverse, the caseback features crisp engraving and hallmarks.

The sub-dial at 3 o'clock shows the date, in a slightly recessed sub-register, giving depth to the otherwise smooth white dial. In a similar fashion, the days of the month are placed at 9 o'clock, with the months of the year at 12. The moonphase is placed at six o'clock, with graduation for moon age above. The white dial is further accented with applied index markers - corresponding harmoniously with Audemars Piguet’s ‘stick’ hands. The index markers and hands are subtle in form, with excellent legibility against the white backdrop. 

The Movement 

This Quantième Perpetuel 25717PT is powered by the manual-wind calibre 2003. The base movement, developed in conjunction with ébauche maker Jaeger LeCoultre, was first developed in 1946, remaining in production for half a century. 

On top of it, Audemars Piguet added their 2805 QP perpetual calendar module, giving the movement a total thickness of only 3.19mm. The movement is beautifully finished, with exquisite chamfering on all angles, polishing and decoration, in the form of Geneva striping.

The Set

The watch is accompanied by an Extract from the Archives. It's fitted to one of our Stockholm grey grained leather straps, with both its original black Audemars Piguet strap and platinum AP buckle included.
