Well if that should happen I would take the bridge off and apply more. I dont remember that ever happening to me though. I always apply a big o heap. Hard to imagine the space between the jewels ever running out for how much ever you can fit in the concave before running off to the side.
You probably have a really good technique. In my experience, filling the sink doesn't come close to making the right sized circle under the cap jewel. If it works it works!

There's a commercially made "oil pusher

Oh, now I understand! I bought that thinking that it was to drop a precise amount to the end stone, Incablock specifically. When I found that it does not drag any oil I almost wanted to feature it on my topic of  tools for laugh. Happy that I didn't, because I would have been the tool to laugh at!

jewels like this are used to reduce friction. I have an image where you can see the side view Then for lubrication you can try to put a small drop on the cap and carefully put it back in place without moving it around but that usually isn't the best way.I also have an image showing how to do that. then at other option for lubrication is a automatic oiler. You can insert it through the whole from the backside the oil will flow out.

Can I ask for the source of this oiling graphic? Is this from a book or a file, I got really interested to it.

They are two separate PDFs.. One of them is an ancient Omega document that I scanned to a PDF which covers really quite a bit of what you need to know to lubricate the watch Then the other comes from a  document by Seitz Just can't quite remember which one I got it from so I'm attaching something that has the equivalent..

      Usually the coiled spring contacts the piezo sounder and the finger spring is the ground.

      How to store one dip

      By Waggy · Posted

      So I checked with my friendly local lab supplier and they can supply the following in 2.5 lt bottles: Tetrachloroethylene (B-Dip) - approx ￡65 Trichloroethylene (one-dip) - approx ￡43 n-Heptane 99% (Essence of Renata) - approx ￡35 Hexane - approx ￡45 I can't import or buy locally the 'real' products, hence the raw chemicals above. What do you think would be my best option? I'm edging towards Trichloroethylene - I know there are greater health risks, but given the very small quantities used for each treatment and 99.99% of the time it will be sealed in a jar, I think any risk is vanishingly small? This is mainly due to its assumed superior cleaning properties, or from the experience of this group, is the extra cleaning noticeable compared to its safer alternatives?

      Blew it with a coil

      By Kkramme · Posted

      Unfortunately after much investigation, apparently the coil has been discontinued! Shall I get my service guy to try the solder or the conductive paint? 🎨 Final recommendation please🙏

      Eta 2970-1 rotor mount stops watch

      By Dmitry · Posted

      Here are the pics of the bridge. Looks correct, but as soon as I screw on the rotor, the watch stops. Video here: https://1drv.ms/v/s!ArG5E62RGctxjokY5ws85BzuJLVakA   Pics. Might have figured it out. I have been working on this watch for a while and since I got it as a non runner in a terrible shape, there was no guarantee that parts were proper. I think the main screw that was used on the rotor was too long, so it was stopping the main train. As soon as I fished out a much shorter and larger headed screw, things were good again. Please celebrate with me.

      B-Dip residue?

      By KarlvonKoln · Posted

      One-dip or naphtha should be safe, but are you sure it isn't magnetized?  I would also check that.  Although, if that balance is from an Elgin 760 0r 761, I would think it would have a hairspring of non-magnetic alloy.
