I have had a Casio watch on and off for 20 years.  This lives up to the reputation.  They are droid like in that they are not pretty, but are sturdy.  They have added some interesting, but for me un-necessary applications: digital compass and temperature. All other functions are great: time, stopwatch, and alarm. This specific watch should not be used by tactical operators as the metal around the face is dulled but shiny enough to be noticed, get the G-Shock.  The metal around the face does make it slightly more dressy (if that is a word) than the G-Shock.  Great for camping or just rough duty in the yard.  Numbers are large enough that even without my reading glasses in the middle of the night I can hit the illumination button and read the time.  The set up is a little complicated, so give it to your teenager or preteen to set up if necessary.  The four buttons can be found easily in the dark at night.  Illumination off the face will give you about 2 feet of glow at most.  Great backup for a dress watch.
