Audemars Piguet Royal Oak Tourbillon Extra-Thin

About this reference

The Audemars Piguet Royal Oak Tourbillon Extra-Thin reference 26510OR.OO.1220OR.01 was introduced in 2012 to commemorate the 40th anniversary of the Royal Oak and remained in production until approximately 2019. This reference features a 41mm case and integrated bracelet crafted from 18k pink gold, housing the manual-wind Calibre 2924. Collectors value this model for its 4.46mm movement thickness and the "Petite Tapisserie" dial pattern in blue, which contrasts with the warm gold tones. The tourbillon carriage at 6 o’clock serves as the primary visual complication. On the secondary market, this reference typically trades in the mid-to-high six-figure range, often between $160,000 and $220,000 depending on condition and provenance. A notable production detail is that this reference preceded the "Evolution" series, maintaining the classic dial proportions and logo placement favored by purists before the brand transitioned to the 26522 series.
