When my children were toddlers I had this Casio watch. I used the stopwatch and the timers for everything from "15 minutes more of play" to 10 minutes in time out for one. I loved this little watch. It was faithful, accurate and kept on ticking no matter what. It is water resistant- which I accidentally tested several times.  Like several other reviewers have said - usually when I bought a new one it was because the band broke or I lost it.
I was unable to find them in stores in recent years, even though I asked. No one seemed to have heard of them. Then I found it on Amazon and ordered it. Hurrah! I love it. As before it is great. My only concern is I have gained weight over the years and with my fat wrist it is only able to hook on the very end. But that's my fault - not the watch's. I appreciate things that are made with quality, and this is one of them. I have wasted money trying to find a watch that keeps running and lasts. This one does.  They even have a similar one with a metal band for dressier occasions.

Update - I bought this in Sept. 2012. It is now July of 2013 and this little watch is still going strong. There are some things that are still well made. :)
