I would also include the SkyD for it's bezel control system.
The D Blue is simply a Deepsea with a blue gradient dial so me for that is not quite original but just a change of dial. The AK could be considered original but again Rolex just changed out the dial from a Milgauss case.
As for the 126719BLRO meteorite dial, Rolex has been using meteorite in other models such as the Daytona, Day Date, DJ, etc...so adding it to the GMT is not original IMHO.
