I bought this watch in August 2011 and it has been perfect so far.  No scratches on the face due to the recessed glass - I was always scratching my previous watches, but this watch still looks new.  The auto set each night has worked great as I wear it 24/7.  There has only been a few times it was unable to sync in the over 400 times it has set the watch during the night (I probably was sleeping on the arm with the watch on those occasions).  Accuracy is always within a fraction of a second according to WWV.  I really like the 4 alarms it has as I've used them to wake up earlier, remind me of an appointment, or any other event I might otherwise forget.  And no worries about the change in time from Daylight Savings and back - that is done automatically, of course.  In my opinion, Casio is one of the best brands.
