Introduction

This Audemars Piguet 25657 proves that it is still possible to get into ultra-high end watchmaking at a relatively affordable price.When we think of Audemars Piguet nowadays, the first thing we think about is the Royal Oak (or the code 11.59 if you’re Jasper). But that obscures AP’s distinguished history of producing beautifully finished and highly complicated watches.Audemars Piguet’s introduction of the ‘Quantième Perpétuel Automatique’ line of ultra-thin automatic perpetual calendar wristwatches in 1978 has been one the most significant innovations in watchmaking in the last 50 years.This ref. 25657 is executed in a slim platinum case, measuring a classic 36 mm. The case features a lovely stepped bezel, short downturned lugs, and an early unsigned crown. Only 1,821 pieces of this reference were produced between 1982 and 1993, of which only 128 were platinum. The case back is stamped ‘No. 156’, indicating that it was produced early on in the 25657’s production run.The ref. 25657 was made with a number of different dials. This ‘Tuscan’ dial is without a doubt the most beautiful among the bunch. The regal purplish blue dial features an intricately carved pattern and deeply recessed sub-dials, that indicate the day, date, month, and moonphase.The ‘Quantième Perpétuel line is powered by Audemars Piguet caliber 2120/2800 automatic movement, which is derived from Jaeger Lecoultre’s legendary ultra-thin caliber 920 base movement. This base movement was of course used, among others, in AP’s Royal Oak, Patek’s Nautilus, and Vacheron’s 222. For the QP line, Audemars Piguet reworked the 920 to include an incredible perpetual calendar complication as well as a 21k yellow-gold rotor.

Description

Audemars PiguetAudemars Piguet is among the holy trinity Swiss maisons d’horlogerie alongside Patek Philippe and Vacheron Constantin. Audemars Piguet has a storied history of producing high-complication watches. It all started in 1875, when Jules Louis Audemars and Edward Auguste Piguet founded the company in the heart of the Vallée de Joux, Le Brassus, Switzerland. This pure, rough and wild landscape, with deep, dark forests, ice-cold waters and the omnipresence of rocks and hills, provided inspiration and raw materials for the Swiss watch manufacture to develop the finest watches. Since its inception, Audemars Piguet has specialized in rare, valuable and highly-complicated watches like perpetual calendars, chronographs and chiming watches. Nowadays, the main emphasis of Audemars Piguet lies on the iconic Royal Oak line.
