I just checked and compared my 126610 LN with my 5 year old Sea Dweller under a halogen light and it definitely has NO AR. The magnification and color of light bulb in the crystal is the same in both watches. I think I know what I am talking about, I used to do AR for AP some years ago.
This is good input as well, especially given your experience in the area. Are you saying that the Sea Dweller has no AR or the 126610? or both?
