Okay I figured I go back to something I thought I "was" pretty good at tonight, and give the 6309 a rest. I had a watch in the drawer with an AS1686 that was running fast and needed a service/crystal etc.
This movements was a bit different than the other 1686's, in it had a three prong shock spring not unlike the Seiko or even Citizen spring. Only smaller. So when it pinged the one from the balance off into g knows where I grabbed a complete balance cock from another 1686. It has the more traditions Swiss "incabloc" spring that you squeeze slightly and hing up. I figure since I had the plate stripped and parts in the US I would just be more careful on the dial side shock and not loose the three pronged spring. While I managed to remove the spring as soon as I set it down it disappeared going to hide with its partner. Not a good night.
Back to the drawer. I pulled a partial movement from my spares so I could finish. Now I go to free the incabloc on the dial side of the second plate and it breaks. The hing stays in the setting but an arm broke...(IIRC I was able to make a go of a movement once with just one arm) Since I have no shortage of 1686's I thought I'd remove the rest of the spring; but for the life of me I can't figure it out. Does the setting need to be removed, to allow the hing side to slide to the outside? There is no twisting or pulling that would free it. I have looked at google for some time without luck. I see that the "KIF" style springs just pull free. The design of the incabloc does not allow for that. I remeber having to change one once on a balance and I had to strip that all the way down, a real PITA. I just could imagine I'd have to do that for the one on the plate???
If the setting needs to come out I'm going to need a "staking set"? which I'm not ready to buy.
So is there a "trick" to replacing these springs without removing the setting? I'm going to pack it in for the night and try again tomorrow.
