Your Walkthroughs and Techniques

Post descriptive walkthroughs of watches you have stripped down and serviced and/or repaired, parts you have made or techniques you wish to share.

This is an interesting section where we post our challenges and how we have over-come them. You can also post walkthroughs and share your techniques.


SECTION RULES

This section is strictly for those posting real step-by-step walkthroughs of actual repair or servicing techniques relating to watch repair and/or horology in general. The idea is that we help each other by describing or sharing our repair techniques, or telling a story of how we have progressed.
If you are not posting step-by-step walkthroughs, such as - you would just like to showcase a completed repair job, then please choose a more appropriate sub-forum for your content. If your post is not deemed to be a legitimate walkthrough then a moderator will move your post to the appropriate section without notice. Thank you for your co-operation.

    • @JohnR725 that's very helpful.  I appreciate the time you took to give those instructions and post the pictures.  below is a picture of my staff, which looks identical to the ones you posted.  The approx measurements I got are: .772 on the left part of the staff; .715 on the right side of the hub; the hub is 1.107; and the overall length (minus the broken pivot) is 5.248; which seem to line up with the measurements you posted.  I didn't think to measure the pivot, which I'll do if there's enough of one left on the staff.  Thanks again.
    • 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.
    • I think it's stamped on the inside cover. 309 I think.
    • 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.
