I still think the movement looks off, and not something that is Seiko produced.
Below is a comparison with a genuine 6R15D. Specifically the area where the red arrow points is way to coarse and also the print on the winding weight uses the wrong font and thickness.
Also if you look closely, there are other areas with questionable finish and fit.

Philip, it's a real bummer that Amazon sold you a fake watch. I would reach out to them and ask for the money back. They are usually interested in resolving these issues, even after 4 years have passed.
Best of luck!
