I don't know why they charge you . . .
When I went to Wempe (Germany) they checked the serial number and even told me that the watch was sold by one of their stores . . .
The only thing they told me that the watch was 99.9 % genuine . . .
If I really wanted to be 100 % sure they would send it to a one of their service centers . . .
We'll for .01 % it's fine for me . . . I can live with it ;-)
Now a vintage watch is really something different . . . but I just wonder if they can really give you a 100 % authenticity . . . .
What I read here on TRF is not every time all the best . . . about RSC's I mean
I bet that there are people (independent) who know a lot more about watches than some RSC's . . . ;-)
Just my .02
