Very sweet Elgin! The dial is in amazing condition - I don't think I've ever seen one that clean on a watch that's over 50 years old. I wouldn't worry too much about the overdue cleaning. I know the experts say you should have a vintage watch cleaned and oiled every 5 years, but I have a sneaking suspicion that's a bit of mythology begun and spread by watchmakers. IMHOP, as long as a watch is running fine and keeping accurate time, the oil hasn't started to gum up and all's well. If it ain't broke, don't fix it.
