About the Royal Oak Selfwinding 41.
In our own words, from the sources listed under the specifications.The 15510 is the 41mm, three-hand Royal Oak with date, and Audemars Piguet still lists it as the current steel model in this size. It took over from the 15500 in 2022. That was the year the Royal Oak turned 50.
The movement, the calibre 4302 from 2019, carried over. What changed was the case and bracelet, which got the wider bevels and more tapered links AP brought to the Royal Oak in 2022. A rotor engraved "50 Years" dates a watch to that year, the only one in which AP fitted it.
If the newer movement matters to you, look at the smaller 15550 instead. It got the new calibre 5900 along with the 2022 case changes.
