With the pallets removed, does the train feel like it’s running freely? And how about as you increase the winding power?
If the power delivery looks respectable, then I’d check for something else obvious like mis-locking. How do you adjust the banking pins in terms of their orientation?
I knocked up this crude little brass tool recently for correcting some banking pins on a JLC. It’s easier with modern movements are you are more or less just uprighting them.
You have a gem there! That Wittnauer is really a lovely piece, and I like the transistor symbol on the dial. Reminds me of when I was a kid in the sixties, and having a “transistor radio” was a Cool Thing. I see that the drive mechanism is very similar to the Luch electromechanicals. On a related note, one of my Luch watches is engraved on the back too... in Russian, so I have no idea what it says; but yeah, every one of our watches has a story.
