I don't want to cause deception (and I hesitate to write this) but I find it little too big for you too...maybe on a strap it will be less pro-eminent.
I think for you the 42.5mm will be more "adequate", and more balanced. But again, it's a question of "style", if you want the watch take a huge place on your arm, in a fashion way, it's ok, but it is certainly not balanced like we see on these photos. Again, if you feel ok with a BIG watch on you, and lug to lug don't exceed the width of your wrist, and you can assume it, no problem.
