Hi everybody

I am trying to repair a Seiko 7009A and the hairspring needs to be replaced because it is beyond bending back into shape - at least by me.

Will any hairspring do or do I need to get one from Seiko?

I don't think Seiko has any hairspring anymore? Try speedtimerkollektions or thewatchcollector on Ebay . Changing  the complete balance is the easiest i think?

OK, perhaps I can get an ETA balance that will fit. The movement works up to and including the pallet lever so I think I can get it working.

Tack så jätte mycket!

I'm pretty sure that you can fit a balance complete from the 7S26. If it is from a B or C version you need to replace the balance cock.

Just found that Cousins has the A version balance complete in stock and it doesn't break the bank. The B/C version kind of hurts and is not in stock either.

Thank you - I'll have a look. It may cost a bit for shipping but it isn't exactly heavy. ;-)

Pile up stuff up to 30 pounds (as in quids not fourteenths of a stone) and enjoy lowest shipping cost; for is cheap to anywhere.
