Sure...
ALS is often considered to be as good or better than even Patek, however the extent of the perlage is lacking in these photos when compared to a Patek main plate:
Note these are not done yet - I took the photos just after the perlage station so additional steps are done after this. But this drawing gives you an idea of how completely the finishing is done in this operation:
Completeness is not the same as quality of course, but I was surprised to see significant areas that were left unfinished.
Cheers, Al
