The page for that watch hasn't been updated since 2011. I wouldn't put much faith in it.
I disagree about the style. A sleek square smartwatch is a lot less ugly than that bulky, messy Garmin. There's no reason to make it round, it's not analogue, it's digital, it displays text and images. Round displays just cut off text and anything that scrolls. Square is far more functional.
What page? I didn't point to any page. The Fenix 3 came out in March 2015 so I'm not sure what you're saying.
Regarding square vs round, if you look at the high-end watch market it's a ratio of maybe 1-10 in favor of the round watch. Why the makers of smart watches thought they could ignore this, I don't know.
