You will be surprised at what gens I have seen QC problems on and I have seen QC issues on a Patek 5980 and a 5990. Also plenty of PP's with movement problems with timekeeping, chronos not resetting and also dates getting stuck when changing. Common issues.
Regarding not seeing alignment issues with the naked eye that is probably true 90% of the time but take a loupe to anything and you WILL find problems with anything at x15 zoom. Increase that to x20 zoom or more and there will be QC issues you see. Like I said and I think you know I handle and deal with PLENTY of gens on a weekly basis and have a big gen collection myself especially Rolex. I've seen shit some people never would expect to see on a $100k gen let alone a $300k gen.
You can look on the Rolex Forums and there are plenty of examples of QC issues on there. I've seen a plethora more of other QC issues in real life in my dealings with gens.
These QC pics that are being debated are at least 20 x zoom on a $500 rep. Relax and enjoy our not going to see a 1mm alignment issue with the naked eye.
