A born Pepsi or “made” Pepsi. Any difference in value?

As others have said, most of the GMTs were uncoded wrt bezel insert. If for some reason one feels the needed to have a watch that was coded and has the original bezel insert then good luck. The inserts are still really cheap to acquire from Rolex. There likely more value to most buyers to have the collection of bezels as well as the watch and papers.
