in setting mode while doing a date gear repair setting the hands got harder to turn to the point it binded up, so i took the movement apart down to the train wheels and removed the balancing wheel watching a video how to service an automatic watch,i got everything back together but now it will not run, the balancing wheel will rock back and forth a couple of times if i hit it but that's it,every thing seems to work correctly accept it wont run,what can i check?
Thanks
