I can find the correct part number for the retaining ring for the day wheel on a Seiko 7S26 or 7S36 movement but not the actual size. Does anyone happen to know what it is?

The part number is contained in the movement parts list which I found in a number of places on-line. Thank you for the offer of help. The part number is 0963300 which is common to both of the movements. My reason for seeking out a part is not because I currently need one but because I wish to properly prepare for modding my SKX007 with a new movement. Yes, I've decided to keep it and upgrade it. Let me heirs (hopefully far in the future) worry about disposing of my watches. 

Hopefully, I won't lose or damage the clip when I remove and reinstall it as I exchange the day wheels. That said, I have a long and rich history of doing just that. I remove such items inside a plastic baggie if possible just to keep them under some sort of control. I'm not always successful so in addition to acquiring a NH36 movement, I'm also going to have a good idea where to find the e-clip should I need one. 

Breaking out my calipers may indeed be the correct route as I have no idea what the correct size is, except it's very small. I can't help but wonder if SII would make such a part in house or purchase it as a standard, off the shelf hardware item. If so, it should be available somewhere other than through Seiko.

      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.

      Hi there Stoller,   Caliber is generally stamped under the balance or thereabouts.  Caliber can't neccessarily be identified by bridge layout. Regs

      Unless you've got any better suggestions Isn't that what this forum is about? It still depends what state the balance is in to start with. Edit You see, it's things like this that really wind me up and make me wonder if it's worth even sticking around, think I'll say goodnight and keep well
