Basically until you've compared a DSN with another PAM rep its very difficult to explain the added value that you have from one of his watches. I agree that there is some questionabilty regarding the swissness of some of his movements but the overall quality of most of his reps is of an exceptional standard.
The crystal on yours looks good as does the CP, the dial is not to shabby either. But yours is a fantasy model there is no original version of this watch. The crown is painfully fugly and I disagree that the case back is OK , it again does not stack up, though its rarely seen it may not be an issue.
It may be the angle of the pictures but your bezel just doesn't look right. It seems to be very cone like and a tad out of proportion with the rest of the watch.
For the price its a reasonable start but if you were to invest in a DSN you would notice the difference.
Anyway I don't think DSN is trustworthy I think you'll find that's Andrew , DSN is actually Davidsen. Hope that clears things up
