As a disclaimer I do like AP !
Key considerations for me are
1) the finishing - makes the Rotal Oak. Real great, but does scratch up. Some see this is making it ‘yours’ others that it detracts from the look. Only you know which side of that you are in
2) servicing not cheap
3) not as robust as a Rolex but then how offer do you really abuse a watch anyway
Given size you are after it looks like a 15450 or 15300 is what you are after. I would go 15300, but for a blue one it is going to get a bit painful to source . Price going up and waiting list at AD’s
Good luck with the chase
