To the topic - the movement in my VSF 126610LN is shit. The date quick set broke after about two months, the power reserve is nowhere near the advertised amount (when fully wound it lasts about a day, but strangely in the night it looses 3-4 hours and runs normal again then) and it's also not super accurate. So I guess I will get a replacement movement if possible as soon as VSF starts again. If I can't get a new movement, I will probably just get a new watch.
I had back luck with mine also. It wasn't running well, maybe -20 s/d so of course I wanted to regulate it. The first time I touched the regulator arm, the movement became completely unstable. I couldn't get it to settle back down even after a servicing and hours of tinkering. In the process it stopped winding manually and I had to make a replacement washer to fit on top of the intermediate wheel. I was able to procure a new balance M2M.
After servicing before new balance, best I could achieve
After new balance
Intermediate wheel that permits winding -original rep part
Rep washer on right, homemade replacement on left
Replacement installed
Then as a result of many removals and installs of the train bridge the top pinion of the escape wheel broke. I replaced it with a gen part but it wasn't compatible with the rep pallet fork so that had to be replaced with a gen also.
A new movement is about $250, so I still came out ahead but it was a bit of an ordeal to get it working right. Bosshua007 and Trusty both said they could get the movement, but that was before the raids.
