Once upon a time (i.e. a few years ago), a franken meant any watch that was put together out of genuine parts--ALL genuine parts. This standard has been relaxed considerably, to the point where a Noobmariner with a Rolex crown is sometimes called a franken. Some say that you need at least a gen dial or movement before you can say you have a 'true franken'. But until the Franken Regulatory Commission of Geneva rules one way or another, it's a tedious argument over semantics. All I care about is honesty over the parts you've got.
And maybe some guys could take it easy with calling their watches "super franken", "hyper franken", and "double secret franken"!
