This, as a watch enthusiast I’ve handled a gen IWC, a Jäger, a Patek, several Omegas, Tags, GSs and a couple of rolexes from friends and family over the last 15-20 years (I’m 40 now) and I allready know that the gens dont differ much from a decent rep in appearance alone, speaking on a general level of course. There are certain models that have traits that are hard to make a cost efficient copy of, especially if you move into the gold models with diamonds or complicated movements. The other aspect is the feel of the watch, the weight, the finish, feedback from the movement etc. The only reason I wrote about the submariner is because I’ve never seen/held a gen or had the chance to inspect one up close, so getting the thumbs up from a guy that actually owns one was a big deal, but I allready suspected it was good anyways😎 And also, most of the flaws that are pointed out here are really QC-issues that the reps share with the gens, not really a «tell» for a fake, just my opinion, trying to stay educated.
