Pic request. AP 15300,400,450 with Rolex

[1AP]

Hey guys. Considering picking up one of these beauties with white dial. I'm unsure of how they size given their shape.

Can anyone that has one take a comparison picture with their Rolex ?
I currently wear a RG daytona, GV, GMT2c and 16613 bluesy. They're all fine on my wrist just don't want anything much bigger then any of those.
I'm wondering which of the 3 I should shoot for 37-39 or 41.

I'll go see the AD this week to try on the 15400 and 15450 but he doesn't have the discontinued 39mm for me to try and I have a feeling that's the one I'll need.

Thanks in advance.
