These are awesome watches, but my guess is these would be way too expensive for the factories to rep accurately.
I'm not talking about the actual "DNA" materials themselves (obviously the factories don't have access to the Titanic wreckage or moon dust/space station parts :laugh
but to make the reps even "look right" they'd need to incorporate oxidized steel, carbon fiber, insanely textured dials and hands, unique case shapes, etc. All technically possible, but very, very expensive vs. the relatively small number of people who would be interested in Romain Jerome reps.
