My husband had a watch like this for 6 months when the frame around the face held on by screws started coming off and pieces broke off. He has not hit it or damaged it--this is just normal wear.  Stupidly we ordered him another like it before calling Casio about the warranty.  It's still in the warranty period, but you have to send it to a repair center for them to decide whether the problem is covered.  If they determine it's not (it would be easy to say you caused it), you're out the cost to send it to them and/or pay for a repair and shipping that would probably be more than the cost to buy another watch.  Not what I expected from Casio.  I wish my husband had looked for another watch before replacing this one with the same style.  He's worn Casio watches for eons and usually replaces them only because they look worn--not because they've stopped working or fallen apart. This time he's made two mistakes.
