This 1995 Audemars Piguet Royal Oak Ref. 25594ST is representative of the brand’s integration of traditional complications within the iconic Royal Oak. Introduced in 1984, this model evolved from the earlier Ref. 5572, the Day-Date “only”, adding the moon-phase complication. This reference remained in production until 2006, underscoring its enduring appeal among collectors and enthusiasts. This watch has a 36 mm stainless steel case, measured excluding the screw-down original crown, with the Royal Oak’s characteristic octagonal bezel with exposed hexagonal white gold screws. The case shows only light signs of use and retains its original lines, suggesting it has not been polished. The caseback displays the correct reference and serial numbers. The sapphire crystal is in an excellent condition, free from scratches.

The silvered white “Petite Tapisserie” dial positions the day and date subdials at the 3 and 9 o’clock positions, with English indications, and the moon phase at 6 o’clock. The dial is in an excellent condition, with clear printing and markers, it shows only a very light – barely visible – patina and no oxidations or discoloration. Powering the watch is the self-winding Caliber 2224/2825, an automatic movement based on the Jaeger-LeCoultre Caliber 889, is completed with a module for day, date, and moon phase functions, reflecting Audemars Piguet’s commitment to mechanical sophistication. The Jaeger-LeCoultre Caliber 889 is a highly regarded self-winding mechanical movement developed in the early 1980s. It has played a significant role in the evolution of high-end automatic watchmaking and has been used by prestigious maisons such as Audemars Piguet, Vacheron Constantin, and IWC, often with added complications or modifications.

The 889 is known for its thin profile, allowing for this automatic movement with complications to be fitted into slim cases. It has a Glucydur balance wheel and a Kif shock protection system, contributing to both stability and shock resistance. The original steel bracelet, complete with its folding clasp, is in very good condition, showing only light traces of use. The bracelet accommodates wrists up to approximately 19 cm in circumference. This timepiece has been serviced in-house and is in good working order. It is accompanied by a six-month guarantee, an originality certificate, and its extract from the Audemars Piguet archives confirming its registration date as nov. 1995. Collectors seeking a Royal Oak that embodies both the brand’s icon design and horological complexity will find the Ref. 25594ST a compelling choice. Its authenticity and mechanical integrity make it a noteworthy addition to any collection. Worldwide shipping is available, and inquiries are welcome.
