After using the Fossil Sport on and off for a few weeks, I'm of two minds about the design.
On one hand, the watch is incredibly lightweight, which means it's perfect for working out. I barely noticed it while running, and the silicone strap meant I didn't have to be too precious with it or worry about it getting sweaty. I tried the rose gold version, and the face looked great — the gold is a pretty tone, and the watch feels subtle enough to be worn every day.
Plus, I can't say enough about how incredibly comfortable it is to wear for long stretches of time.
But... the overall look of the Fossil Sport was a little odd to me. While the face does look nice, it's attached to a big hunk of white plastic that cheapens the overall look of the watch. That would be fine, except that this watch costs $255. For that much money, you want your watch to look a bit more high-end.
