Seiko have case numbers, I can't see it on your photos. If you can find that we can look for a genuine crown. If not, you need to measure the diameter of the stem, the distance between the lugs and the depth of the lugs. The case number will be something like this. -
I'm not sure what kind of movement this is, but I'm curious to know if you're using the word "lever" as a synonym for "pallet fork"? -
Actually kind of rough, maybe munute wheel pinion problems? Is the 2.73mm canion oinion which seems rarer and not availble on Cousins UK. The seconds hand works and suprising nice amplitude but don't know the lift angle and BE this one says 17 j but is a pin pallet as well. Cap jewels on the escape and drive train pivots. Interestingly in has both water proof and shock resistant on the caseback and dial. Puts this around 1969 or '70? The double bezel that works independently is cool has the pi symbol on each. Wonder if it can be used like a slide rule ir something... -
Any info on matching a new crown to replace the old one would be great -

Thank you, but sadly this did not help. Thank you! There is a handy flowchart. But I don't don't know what the "time rate measuring instrument" is, nor how I confirm my output signal. I'll have to dig further when it's not midnight.
