Royal Oak Offshore 1017 ALYX 9SM Yellow Gold

In Context

At 42 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 15.2 mm it is a tall case, and it will catch on a cuff. 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. 100 m is genuine swimming resistance — more than the shape of this watch suggests it would need.

The movement winds itself from the motion of your wrist. 70 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.

26238BA.OO.2000BA.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a champagne dial with a yellow gold case. It was a limited edition. Introduced in 2023.
