Audemars Piguet Royal Oak Jumbo 15202ST.OO.1240ST.01
Known as Royal Oak "Jumbo" Extra-Thin (steel, blue Petite Tapisserie)
The 15202ST is the steel "Jumbo" Extra-Thin, the closest thing Audemars Piguet ever made to the 1972 original ref. 5402 that Gerald Genta drew. Same 39mm proportions, same integrated tapisserie dial, same octagonal bezel with eight hexagonal screws, and inside it, the caliber 2121, the automatic movement AP has built since the 1960s. This is the watch that made steel sports pieces trade above gold. When AP announced it was ending, prices went vertical, and even after the market cooled from the 2021 to 2022 peak, the 15202ST remains one of the most requested references we see across the counter. We buy and sell this reference on 47th Street every month, so we watch its number closely. The specific .OO.1240ST.01 configuration is the blue "Petite Tapisserie" dial with white gold applied markers and the AP monogram at 6 o'clock, the layout AP restored in 2012 to honor the 40th anniversary of the Royal Oak.
Produced: The 15202 reference line ran from 2000, when it replaced the 15002 and revived the thin "Jumbo" case, through 2022, when AP discontinued it to make room for the 50th-anniversary successor, the 16202. The .OO.1240ST.01 blue Petite Tapisserie dial layout arrived in 2012 for the Royal Oak's 40th anniversary, moving the AP logo down to 6 o'clock and restoring the finer tapisserie exactly as it sat on Genta's 1972 5402. That final decade of production, 2012 to 2022, is the version most collectors mean when they say "15202."

Market & Value
This is the reference that rewrote the steel-sports market. Ahead of the discontinuation, secondary prices roughly doubled off a base near 50,000 dollars, and at the 2021 to 2022 peak the 15202ST changed hands well into six figures, north of 100,000 dollars for clean examples. The market has since normalized. As of mid-2026, tracked market value on the .OO.1240ST.01 sits around 65,000 dollars, up roughly 12 percent over the trailing year but still off its five-year highs. Retail was in the low-to-mid 30,000s when AP still sold it new, so every trade today is a pure secondary-market number. Condition, box and papers, and a fresh AP service history move the price meaningfully; a full set with a recent service commands a real premium over a naked watch. From the buy side, we write checks on these regularly, so we price to the actual bid, not to a list.
What to Know Before You Buy
Three things a buyer should verify. First, the caseback: the .OO.1240ST.01 has a sapphire caseback showing the 2121 rotor, which is the correct look for the 2012-to-2022 run. Second, the dial layout: the blue Petite Tapisserie with AP at 6 o'clock is the anniversary configuration; earlier 15202 dials carried the logo at 12 o'clock with a larger tapisserie, so match the reference suffix to the dial. Third, the caliber 2121 is thin and precise but it is a service-sensitive movement; ask when it was last serviced by AP and factor a service into your number if the history is unknown or the date is drifting. Bracelet stretch and over-polished cases are the two condition killers that separate a strong example from an average one. Full set with box, papers, and the original AP warranty card is worth chasing.
