GW500A-1V G Shock Atomic Solar Watch.  least expensive of the Casio atomic solar that i found.  buttons are pretty accessible.  i had an earlier version which had buttons recessed so much into the body that they were almost impossible to access.  this one is pretty good.  also this one has a little bit more metal in its body.  still an ugly watch, but maybe a little less so.  all in all an excellent buy.
