I know this might be getting a bit off-topic but the term "franken" can be applied to just about any watch that has had it's visual or internal components altered. I think if a watch was creatively altered without disclosure to boost it's value then yes, but to replace a faulty part, whatever that part is to make the watch more useful or reliable is ok. same with changing dials in certain mainstream models. I say mainstream as opposed to something uncommon or highly sought after. for example, if someone had the datejust in question but wanted a more readable dial-hand combo and had original and compatible rolex components for that model installed, then that's understandable as the replacement combo really wouldn't be boosting the market value as much as simply making the watch more useful to it's owner. replacing a weak/damaged case with one that merely addressed that weakness without otherwise altering the appeal or value is also ok. these are old watches and are gonna need some help at times
