I don't know if this has been spoken about, but I just realized there are 2 versions of the logo used in the 15500.
The one we see on the press pictures, and it seems the most common one, is one where the A and P only connect on the top and the bottom, like this:
But there's also a version where the A and P are totally connected :
It seems like the letters are totally connected, and the middle part between the letters is matt instead of polished.
Searching on Google not many like this appear, on Chrono24 some more can be found, it seems most of them are 2021 models, some also very late 2020 ones.
Does anyone know why this happened? Because 2019 models when they were presented have the letters like on the first pictures with the gap, and mine which is one of the latest 2022 ones before the 15510 also has the gap. The ones without gap seem to be in the middle of the production line.
