OK, here is my take on all of this. You can NOT expect the same level of finish and quality control on a $100 - $400 replica as you should expect from a $2,000 and up GEN. There is a reason that the gen costs more. If I get a small microscopic splotch on a rollei rep that goes for $200, I'm not as upset as I would be if I found the same flaw on a $4,000 rollie gen.
The reps we see here are mind blowing. The quality is amazing for the money. But, we need to remember that these are reps. No matter how much you pay for that slightly better date font, and no matter how much you mod the watch, (listen carefully) IT WILL NEVER EVER EVER BE A GEN!!!!!!!!!!
Some people here are very appreciative of what they are getting for their money. I have had other customers that are insane in their expectations.
I inspect all of my watches when I pick them and I hand pick them. I use an eye loupe, and I check several points on the watch. I check for alignment, as in magnifiers being over the date, and the small 6:00 crown being over the 6. I check the silkscreening to make sure the letters are not broken, I test the crown, and the date wheel to make sure that it works properly. I make sure the crown screws in smoothly. I can go on and on, but you should have the picture by now.
Now, I also don't have a lot of time to do this all. so sometimes I may miss a small flaw. However, these tend to be VERY small flaws. This is to be expected, as these watches can't be inspected for everything.
Still things do get missed, and that is to be expected. Also, occasional problems do tend to happen. I can only check a movement b y winding the watch, and setting the time. If the watch keeps good time for a day or two, I expect it will continue to do so. I had one watch that kept great time when the watch was sitting, or on the watch winder. It did not keep time when it was on the wrist. I exchanged the watch. That is where the service of the dealer comes in.
So, be realistic in your expectations, and you will enjoy your hobby a lot more.
