Thanks guys. It's a Seawolf 10ATM pre spring bezel. The case knife stressed me a bit, but eventually got it off and cleaned - nearly seventy years of grime. Thanks. Cheers John

Exactly. This is a pic of the hairspring I'm working on. My horizontal v vertical rates are all over the place. There is no discernible terminal curve. My problem is that the outer coil is (possibly) hitting the regulator pin. It's hard to tell but it looks to be getting very close. Also getting close to the stud, which could be @VWatchie's problem. You can see that I need to adjust the inner coil to centre the collet. That will hopefully solve the problem. But then I'll take the spring off and attach it to the cock to see how it looks. I don't know if it's causing your problem @VWatchie, but I would say your inner coil looks like this

@SargentColon according to the Seitz book the id run from 8-32 hundreds of a mm, so not all would possibly be needed however there were more manufacturers of jewels than Seitz. I’m sure the professionals here would know more than me. This may help Tom Seitz book 3.pdf

Yes this is what I was looking at. I have a 10 year service award from my company with some Amazon vouchers so I was going to splurge on the Starrett set and keep the quality high, but are there standard sizes of holes in Jewels? Would you need all these 91 sizes? is this overkill?
