There are no DEFINITIONS for these concepts. The evaluation of a replica in completely subjective, and some flaws tolerated by you can be not tolerated for other owners and vice versa.
This is a "system" trying to clasify the quality of a replica.
Anyway in PAM GUIDE Section 5.2.1, I'm explaining some criteria to get the evaluations, but I repeat that is very subjective.
SUPER REPS – reps very close to the gen in materials, external look (even in side by side comparison), and reliable
FIRST CLASS REPS- reps very close to the gen and reliable, but with some difference in materials, functions… or little differences in external look or colours only remarkable in side by side comparisons.
BAD-LOW GRADE REPS- reps with evident differences with the gen, different materials, functions, colours, very different movement with a display caseback. In general all replicas which have not any good version and are not at all recommendable to buy them.
I will consider the rest of non classified replicas as GOOD OR MEDIUM GRADE REPS
As you can see this "Evaluation system" is not very strict and there is not a fix rule and less an exact DEFINITION.
Please TAKE the EVALUATIONS as a SIMPLE GUIDE to know something about the quality of a replica.
In general Super replica is a quality accepted in general
Low grade replica is a quality not accepted in general
I know I took a risk with these evaluations, and sorry for the possible confusions, but I think, sincerelly, that it is better these Evaluations than nothing when you are choosing a replica.
