-Description

Audemars Piguet is the oldest watch brand consistently run by the founding family since 1875.

It is sometimes abbreviated to AP from the initials Audemars Piguet.

Together with Patek Philippe and Vacheron Constantin, it is one of the world's three leading luxury watch brands.

This Ref.5548 is a perpetual calendar produced in the early 1980s.

Perpetual calendar is one of the three major complications in mechanical watches.

It is a very useful mechanism that determines the number of days in each month and the leap year, and displays the actual calendar correctly "forever" as long as the watch continues to run, without the need for manual correction until the year 2100.

In French, it is expressed as "Quantième Perpetuel", which is why it is sometimes abbreviated as QP and marked at the end of the caliber.

Ref.5548 was launched in 1978 and is one of the most important watches in Audemars Piguet's history.

It featured the ingenious design of a stepped bezel and the world's thinnest movement for a self-winding perpetual calendar then.

At the time, the world watch industry was undergoing rapid change with the advent of quartz watches.

The fact that Audemars Piguet presented a mechanical complication watch that went against the current of the times strongly impressed the company's commitment to the manufacture of high-end watches.

The Royal Oak is credited with saving Audemars Piguet during the quartz crisis, but this perpetual calendar also had a major impact on the company's stability.

The reference was changed to 25548 in 1984, and a total of 2183 pieces of this model were produced over a 13-year period until 1991, according to records.

The case size is 36 mm, which is very small for a watch with a complication.

The dial is a near pure white dial.

The main feature of this watch is that the lines of the various parts, such as the in-dial characters, are thin, so there are many elements in the dial, yet they are clean and clear.

The month, day, moon phase and day of the week are displayed clockwise from the 12 o'clock position.

There is no leap year indication.

There are subtle differences in Ref.5548 depending on when it was manufactured, but this one can be judged to be a later model from the indication SWISS MADE below 6 o'clock on the dial and the engraving on the caseback.

Later models were manufactured from 1982 until 1984, when the reference was switched to 25548.

The movement is a automatic Cal. 2120/2800.

The baseplate is stamped Cal.2120/2, and some dealers refer to it as Cal.2120 QP, but it is all the same movement.

It is based on the Cal.920 introduced by Jaeger-LeCoultre in 1967, and a perpetual calendar module added to it.

The Cal.920 was used by Audemars Piguet, Vacheron Constantin and Patek Philippe, which shows its high reputation.

The Cal.2120/2800 is very thin as a perpetual calendar movment, with only 3.95mm thickness.

The outer circumference of the rotor is made of 21K gold, showing the fine finishing of each part of the watch, befitting an ultra-luxury machine.

Comes with certificate of origin showing sold in 1987, the part of instruction in Japanese and AP setting pin.
