Nice. Thanks for sharing. Size of date-window appears to be the biggest difference, everything else could conceivably be attributed to different gen batches/years.
Next on my list, still waiting for more comparisons. That's very close, couldnt tell the diff for a sec. The dial also has different engraving depth and size, not that noticable unless beside a gen i guess. Thanks for sharing mate.
Tbh it’s quite obvious if you know what you are looking for. The dial on the zf is way too shiny, the pattern on the gen’s strap is more rigid and refined, datewheel window is a tell as well, and of course zf is thicker than gen. However I’m surprised the clasp on both gen and rep sucks, the polishing is on point for both.
