Checking the condition of a Citizen AS2031-57E , H461 movement, just purchased and stopped for a long time, I found the solar panel of the eco-drive in these conditions (see photo) Probably due to an overheating or infiltration of water inside, I don't know. With the new battery the watch works perfectly, I just have no idea if the solar panel is recharging the accumulator. I wonder if there is a way to verify the correct functioning of the panel And possibly if I can replace only
