                        1- I read CDG Rotor quite offen, what dose CDG stand for?

                         2- I got a 7750 movement, marked VAL,  dose that mean it is a genuine swiss valjoux?

                         3- When did valjoux start producin in Asia.

1. CDG (Cote De Geneve) is the striped finish on the rotor.
2. Some might have been stamped with VAL before it was integrated in the Swatch Group (ETA)
3. Clones are made in Asia and some spare parts. Otherwise the history is in this link.

Thank you HSL, Informative as usual, so mine signed VAL 7750, was produced prior to integration with swatch, therefor, genuine. I red ( on the net) the genuine ones have five ball bearing rotor, mine got seven, what is your thought on that?  Thanks in advance.

The most of the 7750 rotors I'we seen has just 5 balls from the factory, guess it's the minimum amount of balls that will make it last for a certain time.(There has to be an aftermarket too.) Then there are some third-party bearings with 7 balls in them, one could say they have upgraded it a bit. 
I am in no sence involved in Selling these so I put this link here in an informative sence ;)

The old Valjoux 7750 rotor has 7 balls from what I've seen. These have a pressed/riveted bearing, unlike the modern version with the bayonet fitting.

Thank you @nickelsilver , makes perfect sense, I bought just the movement, used, about twenty years ago, it must have worked in a watch like ten to fifteen years, seemed to me, aftermarket bearings are unlikely to have had a market then, good enough to justify costs of a new design/ production, thence, seven ball bearings could have come in old versions, now we know it did.

      I looked at it like this, I've built a lot of stuff in my time, building structures and furniture,those are my creations and they will still be here way way after I'm gone. Traditional watchmakers felt the need to pass their knowledge on, ideas that they created . I assume with them as it is with me, leaving their mark on the earth, a way of being remembered. This creation of Mark's has brought thousands of people together to pass their knowledge around,  ideas that will continue to be used for lifetimes. Ideas that should continue to be procured. If for whatever reason the forum ceased to exist, not quite like Ranfft's, that didn't disappear but much less usable. Then that is sad, such a massive loss of communication between good people and a wealth of knowledge lost. There should be something in place for when that happens which could be next week, next year or in 10 years. Might not be a topical subject for a lot of folk or boardering on controversy, i did say i talk about stuff other people dont. But if you dont talk about it and something happens then you've lost it and you ain't gonna fix it .

      I've remained silent on this thread, and at the risk of upsetting everyone, the thing that worries me the most the the apparent absence of Mark. The moderators do a great job and the members also pitch in, and the site seems to run itself, but it is a concern for the future of this forum when the owner is absent for all intents and purposes. Like many of the comments above I would hate to log in one day and things be closed down as I rely on this site for ideas and knowledge and also cheer me up. maybe the Moderators could reach out to him, assuming he does not read this thread, and express our concerns and let us know the plans going forward? some kind of WRT ark

      That was the exact reason for me starting this thread watchie. Still we haven't worked out how the regulars are going to hook up if it goes tits up. I honestly think something should be arranged to stay in contact, we all help each other so much.

      Yeah ive watched that a few times before,  i couldnt find my old school dividers to scribe it up 😅 Yep thats the guy i bought a roll from . Thanks Nicklesilver that answers that perfectly and more or less what i thought an experiment over time would prove . The jumper arm is quite thick along its length, i left it that way intentionally, i thought the original was probably very thin, i didnt see that it was already missing. Setting isn't particularly stiff as such just positive, i still need to take it out and polish where it mates with the stem release.
