About the Audemars Piguet Royal Oak 15510ST
The Royal Oak was designed by Gérald Genta and debuted in 1972 as a groundbreaking luxury sports watch in stainless steel, featuring the signature octagonal bezel secured by eight exposed hexagonal screws, the integrated bracelet, and the finely textured tapisserie dial that has defined the line for over five decades. The 15510ST represents the current 41 mm self-winding iteration in steel, succeeding the 15400ST and refining every proportion of the case, lugs, and integrated bracelet to meet contemporary expectations while preserving the instantly recognizable Royal Oak DNA. Across references 15510ST.OO.1320ST.01 through .10, buyers can choose from blue, silver, black, green, and grey dials, each sharing the same 41 mm stainless steel case and matching steel bracelet that make this configuration the heart of the Royal Oak collection. The 15510ST houses a certified self-winding manufacture movement visible through the exhibition caseback, a hallmark of modern AP watchmaking.
What to Look For
Within the 15510ST family, dial color is the primary differentiator and the single greatest driver of secondary market value, with the blue tapisserie dial historically commanding strong demand while green has attracted significant collector interest since its introduction. Buyers should verify the full reference suffix — for example 1320ST.01 for blue or 1320ST.04 for green — against accompanying documentation, as each suffix denotes a specific dial configuration and box-and-papers completeness meaningfully affects pricing. Condition of the integrated bracelet, case finishing with contrasting brushed and polished surfaces, and service history are the next factors to evaluate when comparing examples for sale.
Frequently Asked Questions
What is the difference between the AP Royal Oak 15510ST and the older 15400ST?
The 15510ST is the direct successor to the 15400ST and shares the same 41 mm stainless steel case format but features a refined case shape with updated lug geometry, a new generation self-winding manufacture movement, and a redesigned dial layout with revised indices. The 15510ST also introduced additional dial color options and an updated integrated bracelet with improved finishing, making it the more current and technically advanced reference of the two.

Is the Audemars Piguet Royal Oak 15510ST a good investment?

The 15510ST, as the current-generation reference, benefits from strong collector recognition and broad appeal across dial variants, with green and blue dials tending to attract the most competitive buyer interest.
