What about a new sport accessory? It’s hard to recommend one without knowing what sport she engages in, but there are accessories for every sport I imagine. Such as, a set of stylish sweat absorbers.
Tell us a bit more about your friend, what sports she likes, any other hobbies or interests she may have, even her age would let us recommend a better gift.
I don’t recommend that site you linked to, those watches look really really cheap and shoddy, especially for those prices. I imagine they’re bulk imports from China, I can’t wear those watches as they have chemicals which irritate my skin. Plus at that price I imagine the watch will break very soon.
