I did the same on the same watch too...and I'll agree it's tough to tell the difference.Swapped crystals on CF 126506... and I'll be honest, while I am a fanatic for details and insane, I could barely notice the AR difference. Maybe in the sunlight and in office lighting it's a tad clearer but it wasn't a shell shock difference like the 116x series.
I had one helluva time trying to fit a strap with end links on mine. I gave up lol looks good
