I can remember reading somewhere that the 18s Elgin Ball watches had a balance wheel of a different outside diameter than a standard Elgin design. Anyone else know anything about that? I also wonder if the Ball ones had meantime screws in them, since most 18s Elgins didn't have them. Thanks, Ted

Thanks for the help Lindell.I don't see any meantime screws on that beautiful Ball watch, I guess that answered my question.Thanks again, Ted.
