Royal Oak Selfwinding 37 Pink Gold - Snow-Set

In Context

At 37 mm it sits just under the modern norm — the band that suits the widest spread of wrists. At 9 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. 60 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.

15552OR.ZZ.1358OR.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a diamonds gloss dial with a pink gold case. Introduced in 2023.

A variant of calibre 5900, the movement Audemars Piguet introduced in 2022 for the 37 mm Royal Oak. The 5909 leaves out the date, which makes it the first self-winding hours, minutes and seconds calibre the company has built at this diameter. Against the 3120 it replaces it is thinner — 3.9 mm rather than 4.26 — and runs at 4 Hz instead of 3, while holding a longer reserve.

15 other watches in the library run the Audemars Piguet AP 5909.
