I bought this watch for its durability and its features.  I like the fact that it is solar powered.  I wanted a stopwatch and countdown timer with 24 hr. capability.  I also like that the backlight lights up the entire face of the watch.  I don't have to periodically set the time on the watch because it does that automaticaly each night.  Except for two minor issues this would be the perfect watch.  The volume on the alarm is much softer than on my previous Casio watches.  I'm a little concerned that there may be times when it will not be loud enough to wake me up.  Also, I would like to be able to display the time in the small display at the top when I am using one of the other modes on the watch.  Other than these two issues, I really like this watch.
