It's very heavy on the bracelet, mine came off the instant I opened the case and is still unworn. The head wears very well on the supplied rubber, mine wore out and the watch now goes on a variety of Natos. If you get one I'd advise loctiting the threads on the bars. Re wrist size, it depends as much on wrist shape as the circumference. It's fine on my 7" wrist. Perhaps a member here has one and is near to you and you can get to try one?
