This was the only eco-drive I could find with an expansive wrist band.  It is just what I was looking for.  Not having to have batteries replaced is wonderful.  Each time a regular watch is opened up to replace the batteries, it is vulnerable to things going wrong.  I love the two toned effect.  The only thing I would have wanted, would be for the hands to have a glow in the dark effect.  All in all it is great.
