Definitely, his dials have problems. This 1 (below) arrived with the T SWISS T painted white (which is incorrect for a 3-color Newman dial - I re-painted it red), the subdials are a bit too small (leaving a wee bit too much space between their outer edges & the dial's outer minute ring), the coronet was crap (it looked like it was hand-made (with an axe) by a blind man, so I replaced it with a gen) & the subdials are a bit too shallow (the subdials on the gen are set so deeply into the face of the dial that they cause a shadow to appear around their circumference under all but the most direct lighting conditions). But, it got the all-important long-tail 3 correct & the fonts (crisper) & colors (truer) are more gen-like, so, overall, using my rule-of-thumb (does it look gen from an arm's length away or from the next table in a small restaurant?), I bought 1 & replaced my DW with it. As it is now, if he fixed the subdial issues, I would have trouble (reliably) ID'ing this watch as anything other than a gen
Beware that the printing quality of his dials (I am talking about samples of the same dial) varies ALOT & I passed on a number of his previous auctions for the same dial until this 1 came up.
Addendum
1 of NDT's PN dials gets the subdial depth nearly correct. Unfortunately, the rest of the dial is crap
