Franken, in my mind, conjures up a pieced together watch. Usually with a combination of Gen & Aftermarket parts. Franken, to me, also has a faint air of meant to deceive. YMMV.
Like Dr. Frankenstein's Monster, an arm from here, a leg from there -or- a dial from here, a case, bezel from there.
In the case of RSC performing ALL work on watch -NO- it should not be considered a Franken. No different than taking your car in for service or a recall, and the dealership retrofitting some new part.
I would NOT call a watch a Franken that:
1.) Contains all Genuine parts that a given model would have used (over its lifetime).
1a.) as above but fully maintained by RSC that might contain a retro fit (i.e. Lumi Dial where a T dial used to be).
2.) Is an honest to god "Variation" that came out of the factory.
I would call a watch a Franken that:
1.) Contains parts from various models. (i.e. a 16800 dial in a 1680. A "conversion" of a 16610 into a Two-Tone 16613.) Brozak called these "Swap-Jobs" in his book.
2.) (Per Rolex Definition) Contains aftermarket parts. (Personally, I think some of that is crap as certain parts should be excepted, especially if Rolex stops producing them).
Technically, (per Rolex) adding a Hirsch Leather Strap, makes it counterfeit! Crazy!

Final thought. I have collected various other things in the past. ONLY in the Rolex world have I seen a general disdain of potential variations -vs- an actual INCREASE in value and collectablity of said variations. (at least until some big-wig in the Rolex community "blesses" the variation, usually after they own it.)
