1. Please list all the part names and part numbers that did change, and the purpose of the change. Explain in detail the application of the "G" suffix, where/how to identify it, and which model(s) it appeared in. If you can find any 8500 that has a stamped/engraved plate other than the one saying 8500A, tell us and we will all know. (E.g. 8500B, 8500G). I have found none after a year of research. This is personal, hands-on, eyeballing research. (Primary source) THE EVIDENCE IN MY HAND TELLS ME THE 8500B IN BOTH MY WATCHES SAYS "OMEGA" NOT "8500B".
2. The 2 parts I picked on were specifically noted in the video to roll out ">15,000 gauss" technology. These parts were already nickel-phosphorous (Through secondary source research, extensive articles online). Take a magnet and use it to pick up a nickel. Let us all know your results. (Primary source research). I am WELL aware many things changed, but the fact remains, the parts are interchangeable or the designation (C, G) would be clear and evident.
3. Chevrolet did not tell the world they were using a Cadillac V6 (albeit modified) for their base Camaro motor. They just did it and people figured it out later. Customers doing testing without their knowledge. (although the LFX motor did not need testing, the application did)
4. If I quote all sources and footnote/endnote as well as a bibliography, I would have another Master's Thesis. I have already been there, done that. If you don't believe me, provide the information you have PRIMARY SOURCE access to and prove me wrong. Otherwise use your brain and think it through and do your own research (you will never believe me anyway as you already have proven).
All of the is because I nominated a non-speedmaster as "collectible".
Well, lots of hostility for simply asking you to show what you claimed to have learned. There's no need to yell, to tell me use my brain, or otherwise be rude thanks...rather than see this as some sort of challenge if you are open minded you may actually learn something as a result of this discussion, but of course that is in your hands.
I'll address you last statement first about nominating something other than a Speedmaster - personally I have no dog in the fight of what the most collectible modern Omega is. I have little interest (from my own personal collector point of view) in the vast majority of Modern Omegas, so I don't really care what the end result of this discussion is with regards to that issue. However I do care about facts from a technical nature, which is why I asked you to provide some evidence. Customarily the one making the claim is the one to provide evidence of that claim. Saying "I have researched it and you will have to prove me wrong" is not evidence, even though it is a popular approach on watch forums.
Also please keep in mind I asked about specific claims, so assuming I disagree with everything you have written would be a poor assumption on your part.
The differences between the 8500 A and B versions are listed in the technical guide. Only 2 parts change between the A and B revision, and they are:
1 - Main plate changes from 7228500A1002007 to 7228500B1002007 - reason stated is "Engraved new execution" which refers to the movement revision level marked on the main plate. There is an Omega symbol and "Omega" under it - more on this topic later.
2 - Balance changes from 7228500A4005119 to 7228601A4005119 - noted at steel to Si14
If we now move to the 8500G revision, the following parts change:
1 - Main plate is now 7228508G1002007 - Omega symbol and word are now removed from the main plate.
2 - Balance - 7228508G4005119 - staff material changes to Nivagauss on the G version.
3 - Balance cock - changes from 7228500A1005818 to 7228508G1005818.
4 - Mainspring barrel 1 changes from 7228500A20010 to 7228508G20010.
5 - Mainspring barrel 2 changes from 7228500A20011 to 7228508G20011.
6 - Mainspring 1 changes from 7228500A20101 to 7228508G20101.
7 - Mainspring 2 changes from 7228500A2010019 to 7228508G2010019.
8 - Co-axial wheel (what you refer to as "the cog") changes from 7228500A30040 to 7228508G30040 - two lower levels of the co-axial wheel made of non-ferrous material on the G version.
9 - Pallet fork changes from 7228500A40010 to 7228508G40010 - fork and staff made of non-ferrous material on the G version.
10 - Upper shock assembly changes from 7228500A70530 to 7228508G70530.
11 - Lower shock assembly changes from 7228500A70531 to 7228508G70531.
12 - Upper shock spring changes from 7228500A78004 to 7228508G78004 - shock absorber spring is made of amorphous material on the G version.
13 - Lower shock spring changes from 7228500A78005 to 7228508G78005 - shock absorber spring is made of amorphous material on the G version.
Can you please show a close photos of the area near the balance on the watches you have in hand? I'm interested in the area to the left of the balance...you may be able to see an alpha-numeric code there.
Cheers, Al
