About this reference
The Audemars Piguet Royal Oak Automatique Tourbillon reference 25831ST was produced in 1997 to commemorate the 25th anniversary of the Royal Oak. This stainless steel model features a 39mm case and is powered by the caliber 2875, an automatic movement that positions the tourbillon carriage at 6 o'clock and the power reserve indicator at 9 o'clock. Collectors value this reference for its historical significance as the first Royal Oak to feature a tourbillon visible through the dial and its limited production of only 25 pieces. The dial lacks the traditional Tapisserie pattern, utilizing a smooth finish with a date sub-dial at 3 o'clock. On the secondary market, this reference typically commands prices in the mid-to-high six-figure range. A notable auction result occurred in 2022 when a 25831ST sold for approximately $500,000, reflecting its rarity and status among high-complication steel sport watches.
