Casio is my default for cheap and durable. I have a HDD-600 still running on its original battery for at least 15 years (it outlived the original strap which had rubber rot). And when I do change the battery it will be 4 screws and a gasket.

Solar-powered as far as I understand is a gimmick since the solar cell won't necessarily even work well after 10-15 years. Not worth avoiding such a small amount of maintenance.

Yeah, I forgot to mention that the longevity of the solar models is indeterminate due to new technologies. I imagine they will get better and better, though, as solar tech is constantly improving.
