Hi guys, this looks pretty darn good. No disrespect meant here, just answering the question based on my limited knowledge.
The texture on the insert is not as refined and the fonts look a little thinner. Pearl and triangle look pretty good but on the gen, the pearl actually sits below the metal surround and appears opaque. Texture on the dial is similar to the insert in that it is close but not as "textured/refined" as the gen. Lume plots on the gen are flatter/cleaner and more creamy white. Rose gold versus yellow gold on the indices and hands. Bevels slightly more pronounced on the gen. The SEL middle ridge is sharper on the gen.
All very nitpicky, this looks like a very nice rep to me. I will put up some macos I took the other day with my phone here in a second.
