Royal Oak Chronograph 41 1017 ALYX 9SM Stainless Steel - Yellow Gold

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 12.4 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, 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. 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.

26240SA.OO.1320SA.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a black dial with a yellow gold case. It was a limited edition. Introduced in 2023. Beyond the time it carries a chronograph.

Self-winding, column-wheel operated chronograph with flyback.
