Outstanding, can see the time in the middle of the night in total darkness.  That is important in my line of work.  It has a "big" face so it is easy to see in the day.  The crystal is rugged.  The green color is not normally found in retail stores.  I'm glad I got this one to replace my Navy SEALS smaller version that finally wore out.
UPDATE:  This watch lasted me about 2 years.  The strap was disappointedly quick to fail and the lens scratches were annoying.  For seeing in absolute darkness, this is great, but otherwise the quality was disappointing for the price. The price has come down a lot over time.  I would have liked the quality to rise up to the price, versus the price dropping to the quality, but I do miss the ability to see the time regardless of light.  I ultimately replaced it with a much cheaper Timex Triathlon model and have no regreets except for having to push buttons to see then time in the dark.
