The watch is great.  It is a newer version of one that I have had for some 10 years and whose battery no longer holds a charge.  However, the new watch has a different readout than the old and the manual is written around the old display.  Thus, so of the readouts are not described.  For example the far left "dial" is not described as to function.  After repeated observation, I have determined that it is a display of the minute hand on a conventional non-digital watch.  However, the display is strange.  The first time around the segments turn black.  Thus 20 minutes after the hour has the segments from 12 o'clock to 4 o'clock black.  As time goes on and the entire dial fills with black when it reaches the hour, the segments turn white again.  That is 20 minutes after the next hour the segments from 12 o;clock to 4 o'clock appear white with the segments from 4 o'clock to 12 o'clock as black.  Confusing so this dial is almost useless.  Just ignore is is my advise unless Casio can explain it better.
