I have bought the Timex Marathon several times over the last 7 years and not because the watch itself has broken down.I don't think I have ever needed to change the battery!I wear it to work daily and have needed to replace it because of general wear and tear.The settings are simple to adjust.The pulse calculator is a neat feature if you work out.Both the timer and alarm volumes are loud enough so you can use this watch as your sole alarm clock.A great watch at a very reasonable price.Click Here to see more reviews about: Timex Women's Digital Marathon Resin Strap Watch #T5F091
