this movement seems kinda unpopular because not a load of results for it pop up. It’s labeled as a 2220A, whatever that means. I’ve dealt with a seiko style barrel before, but this one has 2 seems and I don’t know which one to pry. 

 

I did see another post about this barrel type and oldhippy said that you’re supposed to buy new ones instead of dealing with cleaning it, or atleast that’s the way I understood it.

 

any help is appreciated. Thank you.

its the seam on the brass side. Seiko does want you to replace them, but for the 2200 series they are hard to find now. you can open it and service it.

 You are correct that is when parts were plentiful. These days you have no option but to open them. Look at the side and you will see a very thin mark around the barrel, you need a very thin blade a razor blade is best to open it. Be careful with the teeth and the cap as it is thin you do not want to distort it.

When I had my compressor set up, I just used my compressed air gun and pump air around the gap between the arbor and the barrel, and the the cap would just pop open. Have a look at the video below on how to do it 

Now that I've retired, I use a brass rod to pry the cap off.

The compressed air is a clever idea.

      Tissot case back removal

      By Neverenoughwatches · Posted

      It's not really shown here , but the blade flips over, so it faces the other way. The knob and threaded case holder then pushes the caseback seam into the blade. Once the blade starts to penetrate into it, the lever and blade are lifted , which should hopefully pop the back off. A lot of fashion style cases have very tight seams and need a sharp blade to start separating them.  Don't buy the cheaper plastic versions of this tool, the posts with the pins through for blade holder break easily if the apply extra force to blade.

      You will still be looking for a balance complete I’m afraid, this is the balance staff, balance wheel and hairspring in one package. Hairspring and the balance wheel are matched in the factory. Whilst we can change a balance staff the hairspring and balance wheel stay together.   Tom

      The hairspring end has come adrift from the small terminal barrel.  I have tried to remove the taper pin to relocate it, but the task is beyond my skill set, eyes, hands and being in my 70s, probably beyond my life expectancy.  It is not too badly mangled on the end.  On the ebay offer, that really is a bit on the rich side.  I'll keep looking, maybe a good hairspring will turn up with a shot balance staff. As for time spent on knees.  I made up one of these from 3M magnetic tape and a piece of wood.  It works well for magnetic parts. Other things I have suffered with.  I found lubricants so very expensive that I bought some very small syringes and tiny needles.  I just decant a drop into my oiling pots when I start a movement and the remainder keeps really well in the syringes. Finally identifying the correct screw for the part led me to make up the board in the final pic.   Thanks for the info. Kind regards   Chris

      Yes that's the type @watchweasol is referring too but I don't like them as you don't get any feel to what's happening.
