I guess we'll see, I'll post some pictures. I had a 15500 recently actually. Sold it on, it was great but not quite what I wanted. The 15202 fits more that bill, its 39mm and wears a bit larger so I've been told and I've worn 38mm watches in the past and it's looked okay. So time will tell!
I had a 15400 and now the XF 15202 and a friend has a gen Oyster Perpetual 39 grape dial and I have to say the 15202 wears almost the same as the OP39. Only for the dial diameter the OP39 even has the bigger one. But regarding the watch case lug to lug both watches are almost similar. But the OP39 has almost the same dimensions as a Datejust 41 so what really wears larger in this case is the OP39 or the DJ41 is much smaller than the 41mm it should have.
So I can‘t confirm the AP wears larger than 39mm. Other models from AP really wear larger, for example my 42mm Diver JF V9.5 could be compared to the Hublot V6.5 Big Bang 44mm I used to have.
