Royal Oak Extra-Thin Stainless Steel / Blue / 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. 55 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

16202ST.OO.1240ST.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. Introduced in 2022.

Self-winding movement introduced to coincide with the 50th anniversary of the Royal Oak. Total of 268 parrts, height 3.2mm.
