··His Holiness Puer SurdusGood progress. I notice that the lift angle in the software is set at 44 degrees; what is the reasoning for that value? The lift angle affects resultant amplitude values.

That's the lift angle for the 6497...
I dont know how reliable the results are. The amplitude seems to look not that fancy at almost full wind, otherwise i tested the results in 4 positions (head up, head down, crown up, crown down) and it looks surprisingly not so bad 😀
Well, glad you have the setting working now. As you state, the balance amplitudes are quite low. By the way, is this a clone of a 6497-1, or 6497-2?
If it's the former, the beat rate is 18,000, and if it's the latter, it's 21,600. Unclear if this is a parameter you have to set, or if the software picks that up automatically. No idea how reliable the readings are with that sort of set-up. honestly although they have serious drawbacks, the cheap Chinese timing machines may be better than the set-up you have there.
By the way, I just had a look at the link that Jim mentioned when you asked about lubrication. Do not follow what's in there - it's really not good!
If you followed that advice and oiled the pinions of the wheels 🤦 it's no wonder your amplitude sucks. So much bad watchmaking in one spot - truly is amazing how bad that is...
Cheers, Al

··His Holiness Puer SurdusUnclear if this is a parameter you have to set, or if the software picks that up automatically.
What caught my eye is the long tail after the drop/banking pulse on the acoustic graph; could there be something rubbing -roller jewel or safety dart? It would explain the lower amplitude...no?

Not really. if the CP is too tight when you get it on an lubricated,
So i applied some a small amount of oil at the cannon pinion before fitting it. thats what i thought you meant i should do.
Good to know not to follow the Service instruction from the link! you saved me some time i guess!

Few days ago i went to a watchmaker who works at the local store (Omega certified) and asked him, where he did his education and if he could advice me some literature for learning. He said i could get the "Die Uhrmacherschule". Thats what they use at the watchmakers school here in Austria i think. It looks a bit dated, but maybe it is fine to start with it. Unfortunatelly amazon only offers 2 out of 5 books..

·It does both. You can set it on automatic or a fixed rate. Currently it is set at 21600. All the displays would show gibberish if the rate was incorrectly set.

··Melbourne AustraliaMy apologies for the "Oiling Instructions".
I just grabbed a pic from the net to show the centre wheel jewel.
When I linked to the site I should have explained that I hadn't checked anything there for accuracy or commonsense.
If @Eve sends me a PM I can provide a copy of the complete ETA technical guide, including correct lubrication details.
