Found a really interesting Chrono for sale, but not sure if dial is original, or if it was re-lumed perhaps. I asked seller and he believes it is all original. He got it 2 years ago from grandson of original watch owner. It looks too clean, so that is why i am not sure if it is a re-dial or refinish in any way. What do you think?




Thanks for the help
