Thoughts on this 1966 Seiko 62MAS bezel? I've been told by a very reputable dealer that it is an original service replacement.

Well, it's not one of the normal inserts I'd expect to see, but I don't really know how to distinguish between an aftermarket vs a service insert. As you probably know, the zeroes are usually almost square looking and the numbers are more flattened down. There are other subtle differences, e.g. small serifs missing,

You can see the differences easily by comparing the "20" and "30". Here is one of the insert styles I've often seen.
