CASIO DURO200 SPEED MEMORY ana-digi wristwatch Battery replaced, operation confirmed. Backlight did not turn on. The silver and black asymmetrical body, the covered bezel, and the digital layout are very cool. It's a very rare model. I don't think working ones come up for sale very often. There are signs of use, scuffs, and scratches. The belt has been replaced with a new one, so it is clean and beautiful.
