Royal Oak Extra Thin Selfwinding Flying Tourbillon RD#3 / 50th Anniversary

In Context

At 39 mm it sits just under the modern norm — the band that suits the widest spread of wrists. At 8.1 mm thick it is about average for a modern wristwatch. 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. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist. 50 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

26670ST.OO.1240ST.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a blue gradient dial with a stainless steel case. Introduced in 2022. Beyond the time it carries a tourbillon.

Self-winding movement with flying tourbillon. Diameter 29.6mm, height 3.4mm. Total of 226 parts including 30 jewels.
