This watch does everything I need:  time, date, stopwatch, countdown, second time zone, solar power, pretty good luminous hands and markers, etc.  Two things to consider:  (1) the digital display is too small for some folks' eyes (I don't have any problem with it, though) and (2) the band and case are really GREEN!  I mean Army, Olive Drab, distinctly GREEN.  I didn't get that impressions from the photos online, but when it arrived.....  Well, I returned it for the black version (AQ-S810W-1AV).
