Thank you to both of you! I've been somewhat derailed by this quandary for a couple of days now. I am guessing that the point of the wider tweezers is to support the whole spring at the same time in an effort to prevent it going under tension... I have already discovered the Zen of a clutter free space, and trying to keep my work well away from the edge, however the most terrifying of the flights wasn't so short, I had my work in the middle of the table and nothing else around. That particular launch was towards me. I distinctly recall feeling the spring hit my left hand as it escaped. I only found it by dumb luck, on the floor, between the legs of my chair. I need to order a pack of replacements just in case. I think I recall a thread discussing where to find them, and the differences between the clones and the authentic ETA ones, pointing out that they're not interchangeable (the clones being longer IIRC). Now I just have to find that thread again. What I haven't mastered is the zen of the search function here. I'm sure I"ll get that down eventually. So this is similar to, but different from one of the posts I had found in my original searches (or maybe I'm just hallucinating, I can't find the post I thought I remember). The bits about the corner filled in a gap in what I'd read before. At least I have a more clear picture in my head about what needs to happen now. Yes, I've learned about how touchy these springs are. What I'm not sure I have a good grasp on is the understanding of what causes the spring to flex, other than to say "the slightest little touch" I think I'm going to try a small bit of Rodico to position the spring next time. -

Hi all, needing a little help. I have an old Casio AQ-321G, but have no idea what battery it takes. I've looked around online, but cannot see anything... I see a 309 stamped on the case back, could this be it....? Can you please help, below are some pictures: -

The radial teeth are for hte seconds register, and the other (which is simple and doesn' take away significant torque from the train) for the minutes register. -
The original 6139A manual is very clear in how to disassemble and how to assemble ...... step-by-step. However I haven't seen the 3169B manual, even in the Japanese version around, which clearly highlights the difference in center-wheel. 6139A Seiko Technical Guide.pdf 6139_A.pdf 6139A.pdf 6139b.pdf 6139B repair guide jp.pdf
