Nice little watch, but there can't be many men for whom the full size Square is too big ! Having said that, it is definitely an option if you prefer the size and can look past the Baby branding :-)
I do, my wrist is a little larger than yours but I personally prefer the smaller option
However, this will not be the right choice for most people.
I've a couple of squares (both are solar and pick up the time sync signal) and enjoy wearing them when I do, I've never found the buttons the easiest to operate though. They're quite small, don't protrude much from the case and have a slightly squidgy feel to them. Definitely tricky to operate with gloves on, for example.
I'd try before you buy just in case, the likes of H Samuel normally have a varient or two in stock.
If you're after bigger buttons, the versions with a screw case back have considerably easier buttons to operate
