There is a special price of the Fenix 5 here, and the difference with the FR935 isn't that big anymore (20 Euros). I wear a Fenix 3 and it is not too big or heavy for me. AFAIK there are no functional differences at all between the F5 and FR935, so the main difference would be the package.
I always scratch the bezels of my watches (my silver F3 doesn't look that bad though) and am slightly worried about the black material of the FR935, is that easily dented/scratched?
