I put my MTG-920DA out in the Florida sun to charge up the battery. It charged up to full, but then went down to half charge again. So I put it out for some more rays. When I came back the second time the entire face was blacked out, it looked like the ink or whatever its is had blead all over the face.
I brought it into the shade and a few minutes later the blackness began to blead back to where it came from. Now it looks perfect and is still fully charged, days later.
ever see that happen? i thought the watch was ruined, but it seems to be fine
