You have the right idea, buy another and keep practicing. I can't find a new balance wheel, so go ahead and try to repair the one you have. Watch plenty of videos first. -
Thank you @Jon, much appreciated! 🙂👍 What type of hammer are you using and is the type of hammer important? -

Hello, I am just starting to learn how to hopefully service mechanical watchs Right now I started by acquiring a bunch of tools and a first practice movement (ST36). Since I got it last week I have been practicing disassembling and reassembling it (I don't yet have the tools and products for washing and lubrication as I estimated that the first step is the manipulation required for assembly and disassembly). To be quite honest the result have been interesting. My first step was breaking the setting lever screw when I was trying to remove the stem (OK practice movement won't be able to set time, oh well). I did manage to mostly disassemble the movement (I kept the balance together, didn't open the barrel and didn't remove any jewels). I messed up the balance spring a bit when removing the balance (I think the impulse jewel was still in the fork or something). There was a small tangle. I reassembled everything and surprise the movement came back to life. I disassembled it again and decided I will try to fix the hairspring. So with lots of trouble I removed it from the balance and when trying to fix it I made more of a mess. After reinstalling everything the balance won't oscillate (likely the spring rubbing on things, either the plate or the cock). Right now I wait for my second st36 and continue practicing while slowly buying what I need to wash parts and lubricate them. Any of you think there is a chance I can repair that spring or find a balance complete for that movement which will cost less than the whole movement?
