I always found them compelling, but my biggest regret, if I am not mistaken, is that these dials are simply stamped and not produced by real guilloche techniques which is not worthy of PP.
My beliefs regarding these dials were driven by close examination and paperwork in a complete boxed set indicating artisanal guilloche. That's the extent of my understanding, so please don't take my word as a Vatican-style "infallible" statement. It's just my best understanding of the 5022 based on what I've seen. Best, Tim
We don't take you for an infallible pope, don't worry about that, but we know that you do your job seriously, with the information you have! And we greatly appreciate your work. Best, Emmanuel
