I am looking at a Seiko Spirit which has the refererence 5M22A on the movement. This watch has seen water ingress at some stage and the movement is badly corroded and beyond saving (although case and dial etc. are fine). I've looked to see if i can find a 5M22A on somewhere like ebay but no luck. There do seem to be other '5M22' references though e.g. with suffixes like 7B30, 6C30 etc. I usually only work on (Swiss) mechanical movements so am unfamiliar with Seiko nomenclature ... I don't know what these suffixes mean and whether they'd be suitable.
So basically can someone point me in the right direction and tell me what Seiko movement references I can look at to see if I can find a replacement for the 5M22A please?
I'm really bad as far as vocabulary goes in this area but here goes:
Judging from the incabloc slot it sure looks like a triple/trior or whatever you call it spring should go in there. I remember working on one quite recently and it had the same system. You'd fit in one "foot", rotate slightly and insert the 2nd and then the 3d.
There's quite a couple of variations so maybe they don't use a "traditional" triple spring.
