Royal Oak Tourbillon Chronograph Stainless Steel / Blue

In Context

At 44 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. The case back is open, so the movement is visible without taking the watch apart, and the sapphire crystal will resist everything short of deliberate abuse.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 72 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

25977ST.OO.1205ST.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue dial with a stainless steel case. Beyond the time it carries a chronograph and a tourbillon.

The 2889 is Audemars Piguet's hand-wound tourbillon chronograph with an integrated column wheel, the movement of the Royal Oak Tourbillon Chronograph. It powers 15 watches in this library. It has 295 parts and 28 jewels at 30.5 mm across and 8.07 mm high, beating at 21,600 vph for a 72-hour reserve, with the tourbillon at 6 o'clock and the chronograph counters at 3 and 9. The [2936](/calibers/audemars-piguet-ap-2936) is the same movement skeletonised; this one keeps its bridges and a solid dial. The glossary defines the [tourbillon](/glossary/tourbillon) and the [column wheel](/glossary/column-wheel). In the library it powers 12 [Royal Oak](/brands/audemars-piguet/royal-oak) references at 44 mm, the 26116 and 26377, and 3 [Jules Audemars](/brands/audemars-piguet/jules-audemars) Tourbillon Chronographs. 2 are limited editions. The [2885](/calibers/audemars-piguet-ap-2885) is the maison's grande complication, and the [2924](/calibers/audemars-piguet-ap-2924) its ultra-thin tourbillon without a chronograph.

14 other watches in the library run the Audemars Piguet AP 2889.
