nhoJ said:The solar Casios that I have owned have never moved from a HIGH indication on the power meter. Granted these have been digitals with low power demand, but there isn't much sun in the winter time with long sleeves and I don't bother doing any sunbathing of the watches either.
I've only owned one EcoDrive and it didn't have a power meter, so I have no idea how well the charge was kept. I never noticed the 2-second hop, though.
One thing I like on the Casio digitals is the use of a power saving feature which shuts down to minimal functions in the absence of light. This can really increase the life of the charge, especially for watches of infrequent use.
