This Casio watch is a bit pricey but comes with multiple features. It has a built in compass, temp reading, longitude, latitude, sunrise, sunset times, multiple major cities home base settings, light, moonage, an alarm, world time, stop/start watch, date, and oh yeah it also tells time.  It took about ten minutes to set it up the way I wanted.  I had to set my home base as Denver being in central time zone it was the closest major city on the list but I set my longitude and latitude to my home town.  The time sets itself once you set the features correctly to your time zone.  Then all I had to do was choose daylight saving time in the preset features and the time adjusted itself to fit.  The compass feature is nice the second hand points north and true north.  Easy to use and set once you familiarize yourself with the features.  I am hard on my watch glass and usually scratch the glass within moments of having it on.  I have hit the glass twice by accident on the wall and other household objects and so far no scratches. The only thing I can find that I wish could have been better is the arm band.  It feels like cheap plastic and I wonder how long it will hold up.  I could always replace this because the watch itself is sturdy and solid.  It is also water proof up to 100 M.  If anything goes wrong with it in the upcoming weeks I will add that to this review for now I have only the arm band as a complaint and I will wear it to see if it holds up.
