You can count on a Timex and this 'clip on' is no different.  I bought this watch because there are times, due to inflamed ligaments in both wrists, that wearing a watch on my wrists is too uncomfortable. I picked this one because of its name and the fact that it was constructed to take the abuses in casual clothes environments.  I just wish I had another, maybe a bit nicer, to wear when dressed in suits and jackets. My only complaint with this watch is that it is difficult to change the modes easily - I have to steady it with one hand while I change modes with the other.  This one fact doesn't ruin the watch for me although a bit aggravating.
