So one thing I've noticed on Speedmaster reps that aren't the moonwatch (i.e. The ones with the manual hand wind) is that the reps are pretty expensive and there are a few subtle flaws. I know from experience because I have a rep of the Speedmaster 57 (the watch to the right in your picture above). I looked at the rep at the link you posted and it seems that that the price point is exactly the same and the small flaws are still evident. 6 and 9 markers are slightly mis-aligned and the left Lume marker the the left of the 12 o'clock marker is also mis aligned. The 6 marker tends to lean closer to the "Swiss."
The 3 o'clock sub dial is also most likely faux and not functioning. One thing you could do is get a watchsmith to freeze both the hands of the subdial at 12. Probably the biggest flaw is a sunken date wheel although the ones in the photos in your link don't look terrible. However the font is too thin as compared to the Gen.
IMO it's a great rep and is a fantastic looking watch if you are willing to look past the flaws. Granted these watches retail at $9,000 (at least the 57 model does) and you're paying $498 for a replica.
I actually compared my rep to the gen in a boutique and when you're casually looking at it the similarity is pretty good. You wouldn't be able to tell the flaws if it was on someone's wrist. It's only under close and careful observation that you would notice the subtle flaws.
Some users in this forum might be able to modify the hour markers so they are in proper alignment to help reduce the visible flaws.
