I am only a beginner and have not serviced many different caliber but those, that I have, I did it for several times.
6497/8 and a seiko nh35a, this last one a broke a barrel tooth and still waiting for a replacement.
For the 2824, I've been using chinese copies before I service a tissot with a 2824 that I own.
Here I already destroyed a Balance ( I don't think it was my fault. The quality of this movement is really miserable. Costs about 25,00€), lost a click spring e broke a escape wheel pivot in the watch cleaning machine. But now I can assemble and disassemble everything with my eyes closed.
Where I still have a lot of problems is with the Balance Jewels and oiling the escapement.
My readings for rate and amplitude are always ridiculous. It starts with +75, then I clean the jewels and replace them. Then a have a -50, after that I oil the escapement and achieve +20. Then I disassemble the balance, clean it and do it all over again. After 5 hours I get some acceptable results. And this happens sadly everytime....
