Your question sir is one for the ages. The definitions seem to be quite flexible depending on which forum you visit, and whether you are a buyer or seller!! I believe that we here on this forum are a bit stricter in our definitions, but they are definitely open to interpretation! But to partially answer your question, I would say that a franken has several crucial genuine parts, let's use Rolex for example. I have a Rolex day/ date it has a genuine dial, Tudor hands, genuine bezel, crystal and crown. Is it a super franken? Not in my estimation, as it has an after market case and movement, also an aftermarket strap w/ a gen buckle. It's a very nice watch, and highly frankened,but not a super franken.
Most folks here believe that to have a super franken, the preponderance of parts have to be genuine. So let's say you build a Rolex 1680, MBW case, bezel, genuine insert, pearl, dial, hands 1570 Rolex movement w/ gen open 3,9 Silver DW,gen crown, gen 580 endlinks, gen 9315 or or 93150 bracelet/clasp. That sir is a super franken in my estimation.
In the truest sense of the word, to a purist on a genuine forum, a "Frankenstein is composed of all genuine, but non matching parts. We obviously have a somewhat looser interpretation here.
Hope this helps.
