Aftermarket vs genuine GMT Master bezel inserts

[rattyray]

Hi folks, would appreciate some help determining whether this bezel is an aftermarket or genuine Rolex bezel - I took a look at some resources on the forum but I have a terrible eye for these things - would appreciate your thoughts.

I’m no expert but I’ve seen enough 1675 posts here and on other forums and I’m going to say get an expert opinion. Some are blue or red or mix color on the rear and it’s a bit confusing especially if you’re about to drop $2k or more on it.

Helpful context - for reference, these are 5 digit reference bezels (16700, 16710, etc.)

It’s genuine, non serif.

Got it - are you aware what period these non serif dials were from?
