Brought it to my local rolex guy, he has the timing machine for various movements(although not co-axial.) Verified with him that if there was a fake movement (asian or swiss ETA) in there his machine would be able to record the beats no problem. The read out came all gibberish using all four readings, which means it's a co-axial movement. I didn't feel like driving 30 miles just to have a guy tell me the same thing, and I don't want to open the case back and void the warranty just yet. Was 90% sure thanks to you guys, now I'm 99.9% sure
