I do not have any pictures as I am at the office... but I've had both watches. I guess it's a personal opinion, but on my 7 inch wrist the 42mm PO was much better than the 45mm. However, I have seen many choosing the 45mm with the same wrist size.
Again, it is a personal decision but I would definitely choose the 42mm. I can try to get hold of some pics when I get home if I still have them.
