Looks good. The date font is a little thin. The case/polishing/crown width no one will notice unless comparing next to the gen, and even then probably not. The truth is that most people don't know what a Patek is, the few that do never held a Patek in-person, and the very few that held a Patek (or the .000001% that own one) don't spend time reading RWI to know that the angle of the polish on the lugs is imperfect.
In short, no one you run into in real life will distinguish this from a gen as long as your lifestyle affords such a timepiece, and you don't take it off to display the movement to someone proficient in high-end watches.
IMO, for the price the white 3KF delivers on most counts. I ordered the 3KF with an SWF green dial, but sometimes wish I would've just saved the time and money and ordered a stock white dial.
