Well fiddle sticks!!!! I have corrected one problem but created another. I figured out that I didnt have the hammer mounted correctly. I fixed that and things seemed to function a bit better at least between depressing the buttons. I got a little confident and figured the crazy reading I was getting on the time graph was due to a bunk balance. So I decided to look into it. I have two assemblies. After a closer look these too seem to be different. I noticed the hair springs didnt seem to have a nice concentric layout when put in place so I decided to try and tweak them. That was a mistake. So far the only thing that really makes me a bit nervous is when I start messing with the hairspring. If I can find a good balance assembly id rather just drop the coin on it rather than try to fix them. Ive included pics of them. I will order a complete balance assembly, if I can find one. I have a hunch that the grinding im feeling when turning the stem is due to a bad sliding gear so I am going to swap that out as well.
It's my own homemade balance tack. Took a prescription pill bottle cap and some odds and ends lying around and voila. You can buy them too but there's something special when you make your own tools. You appreciate them more I find.
That is certainly an option. They should be available, and hopefully not eye wateringly expensive either, however it may be possible to fix the one you have. Just put on your safety specs and crack it open.
I think a 2770 series barrel and mainspring would be correct, but check before you purchase.
Something like this perhaps - https://www.ebay.co.uk/itm/ETA-Calibre-2770-Part-182-Complete-Barrel/222524899179?hash=item33cf847f6b:g:NLkAAOSw4CFYwvVt
Also confirm with the supplier that it includes the spring.
