A fantastic condition 1990s Audemars Piguet Royal Oak reference 25594ST with an ultra rare (19ex. made) Diamond-set indexes black dial. 

The Audemars Piguet Royal Oak reference 25594ST, introduced in the mid-1980s, represents one of the most refined evolutions of Gerald Genta’s iconic design, distinguished by its triple calendar and moonphase complication. Crafted in stainless steel, this model preserves the Royal Oak’s hallmark octagonal bezel and integrated bracelet while adding a layer of horological sophistication through its beautifully balanced dial layout. The subtle tapisserie pattern, often seen in tones of silver, grey, or blue, provides a textured backdrop for the neatly arranged day, date, month, and moonphase indications—an elegant expression of mechanical artistry within the sport-luxury framework. Powered by the ultra-thin automatic caliber, the 25594ST embodies both technical finesse and timeless design, offering a poetic blend of precision and aesthetic harmony that makes it one of the most desirable and collectible complicated Royal Oaks of its era.
