Why would you even remotely care about the serial number on the movement? Do you see the movement? Because I certainly do not, crazy I know but the stainless steel back of ALL Rolex cases sort of prevents that.
As for you have doing research, I and others here are sceptical at best. To me, you look like you're waiting to be spoon-fed just like the other 123123123213213 new members daily think they can ask.
Go on the search bar, type in ARF - Submariner / whatever you're looking for. Eg. "ZZF submariner, Noob v10." Find the thread... read the last 20-30 pages of each thread that you're interested in. If you're then struggling for information, go back to page 1. After that, you'll be able to ask specific and pertinent questions.
Not made up mumbo jumbo about serial numbers, you're fooling no-one. Go read.
