I think it depends on the watch. Because some watches are actually very elegant in a smaller size, and it is not only the 36mm what counts but the lug to lug size and thickness.
I thought that they had a 35mm version of the PRX. Maybe that is a perfect size. If 40mm is big on this watch, then it would also be big for a 35mm watch but maybe that is just the perfect size.
