AR very good, but not equal to Gen.
The main thing in my opinion is that the engraved numbers around the bezel are not as deep / crisp as Gen.
Some of the dial colors have inaccuracies, as well.
Date wheel will be more sunken, especially if Asian 7750.
Rep bracelet more accurate than rep strap IMO.
Bottom Line: if you like it, get one it is a great watch and one of the best reps available.
Right next to a gen you would know the difference, but other than that it looks and feels like a gen watch and is very accurate, every rep has some flaws.
Cheers,
