I am saving for my next watch and the royal oak has my attention but have ?'s.

[Stonedcl]

I have been saving up for my next watch and I was thinking a pp aquanaut but the more I see the royal oak the more it is growing on me..
I currently have a date just , subc, and Tudor chrono.. I do have some questions , I really like the 15300 models and am seeing them on here for 10k range but also love the chrono white dial 2560st? I see that they Are 39mm and am wondering if they make the 36mm still?
I have a skinny wrist mabee 6.5 inches and love there bracelet but am not sure how it would sit on my wrist, I don't want it to look silly as the 40mm subc is borderline for my skinny wrists.. I also see the date models have clear case back but the complications do not is this common?
Can someone with skinny wrists post some wristshots of the 39mm and smaller ones if you have them ?

Thank you.. Hopefully I will be one of you guys soon..
