Some things I've seen (thanks OP for link)
- "Gold" bezel and crown is too dark
- Rep crown is thinner than the gen crown
- Pearl looks funny. It's off, but out of all the parts this is probably the easiest to replace if one exists/comes around
- Case seems a bit wrong; rep side profile looks a bit fat on the ends compared to gen. Also, the top of the middle on the gen doesn't look like it slopes downward as much as the rep
- Bezel ridges aren't as well defined on rep
- Case back engravings deeper on rep (doesn't look bad though; I'd take it)
- Plating color is actually quite good
- Kind of difficult to tell, but the xtal profiles look different between the two
That's mostly what I see for now
