Partially verified

This Audemars Piguet Royal Oak reference 25572ST is a 36mm steel wristwatch featuring a Petit Tapisserie white dial. It is equipped with an automatic calibre 2124 movement and displays day and date indicators through two sub-dials. Originally introduced in 1983 as reference 5572, this model was later renamed 25572 and represents the first Royal Oak iteration to include a calendar complication. Production of this reference was limited, with the source noting a total of 1,770 examples, of which 576 were produced in steel. This particular watch is attributed to a 1985 production year, with a cited production number of 12xx. The watch is presented on an integrated steel bracelet sized to fit a wrist of up to 18.5cm. The auction description reports that the movement has been serviced, and the object is supplied with a handmade leather pouch.

Object description

Design and Dial Features

The timepiece is constructed with a 36mm stainless steel case and an integrated bracelet. The dial is finished in a white Petit Tapisserie pattern, which provides a textured background for the applied hour markers and the central hand stack.

A primary feature of this reference is the inclusion of day and date sub-dials, which deviate from standard central calendar displays. The day-of-the-week is indicated at the upper position, while the date is indicated at the lower position, each operated by a dedicated sub-dial hand.

The watch is powered by the Audemars Piguet calibre 2124, an automatic movement designed to accommodate the calendar complications. This movement provides the energy and gear train necessary for the sub-dial day and date displays.

The auction description reports that the movement has undergone a full service by the vendor's watchmaker. The reference 25572ST is noted as the first instance of a Royal Oak model incorporating a calendar complication.
