Thank you. My sweet spot is exactly 43mm, but I think the 45mm would look too big on my wrist, because it has a very thin bezel and it looks larger than its size would suggest.
I also got a Panerai PAM687 today, which is 47mm and I think it looks ridiculous..
My 42mm Avenger GMT is the perfect size for me:
The strap on the Zenith is not of proper size for me, I'm between holes and I just can't strap it on my wrist comfortably. I think it will go to M2M very soon. It's a shame though, because it's a very well made watch, it feels rock solid. And the movement seems to have a great PR, I just tried the watch on and gave it a few shakes and it's been running on the table for hours
