My daughter just got her second Armitron watch, the exact same model, because she loved the first one so much!  The first one lasted 3 years and the battery just died out.  The only reason why we just bought her another one was because the face of the watch was scratched up and the color was fading, but hey after 3 years of VERY active use, I can see that happening.  My daughter wore it 24/7 and absolutely loves everything about this watch.  I would highly recommend it for active people.
