Hi Brad,
thanks for the answer , and explaining the reason(s) for pointing these 2 out. I can only speak for myself here, but I am quite pleased seeing some hard to find parts being put up for sale on *bay. Recently I found a complete NOS 809 case incl. dial , case , reptile strap but its missing the movement and hands and I am very pleased that these parts *do* turn up from time to time.

These parts give me the opportunity to 'build' or 'complete' my watch , and I might even sell it later on . Does this mean it is a 'frankenwatch' or 'fake' ? (this is a general question, not specifically aimed at you

) I tend to think it is still an original , as long as it was build ('restored' ?) with original and age correct parts.
As I am getting more and more interested in vintage 806 and 809's , and recently found out how hard it is to get , for example, an all black sliderule ring , I am picking up parts left and right (dials, movement parts, sliderule rings and the occasional case) just to make sure that I do have some parts , in case I need them later on. (does someone have a set of NOS hands please

)
I thank you for the warning(s) that you give , but not all people that buy 'just the parts' are fraudsters or trying to scam

,but it is worrying to see that more and more really fake vintage watches are fetching very high prices !! .
And as you rightfully stated , there are some real experts on the board(s) and when in doubt, ask !
Rgds
