I've ordered the rep and I'll do a side by side comparison. I also have the gen F series. So it should be pretty interesting
My early reflections on the quality of this piece are EXTREMELY positive. The only real tells that I can identify are:
the bezel pips: my gen has a very sharp edge on the pips, with almost no bevel. The rep appears to have the typical soft edge on the pips. Also they should be perfectly mirror polished, providing an amazing contrast with the brushed bezel. Rep pips typically aren't very well polished.
The hand color: as usual too yellow. I actually do have a set of gen sub hands that appear that yellow, but this is very rare. Ideal lume color should be a greenish C3/vintage yellow mix. Ironically the color from the PAM243M is a perfect match for gen tritium color.
The CG: although not terrible by any means, the inner corners appear far too square.
Overall this looks to be an amazing rep. I'm very excited to see it in person.
