Personally I prefer to bend the balance bridge when it's out of the watch. Although typically I'm doing American pocket watches and it actually takes quite a lot of force to bend the bridge. But if you would like a lever and it's a wristwatch or something smaller than a pocket watch the Swiss have you covered as they have a lever or two. I remember somebody pointed this out to me and I looked at the tool and can't remember why but I was not impressed. I suppose the real question is why do we either method? In other words the watch left the factory without a shim unless of course it's a Russian watch and then it definitely had one plus a few other companies also had them but typically the watch doesn't need them at all. But with anything of vintage things have happened things have well things aren't always where there supposed to be. Then people change balance staffs and don't realize that pivots can be shortened. I saw a picture of a Russian balance staff and noticed they have extremely long pivots but apparently nobody has a lathe Or fail to grasp why the pivots are so long and shimming. But it would really be best if you didn't have to. Then for doing any of the things like we talk about you really should be practicing on a practice watch. Or even pieces of watches you don't even need a complete watch you just need the balance wheel on the bridge in the main plate see them practice bending things and see how much worse it takes to break etc. As everything requires practice and practicing on a watch you want to keep when you have no experience isn't necessarily what you want to do as it will lead to probably what were seeing where things are going to get much much worse before they hopefully get better hopefully Then I'm attaching a PDF on balance wheel truing. If you work on American pocket watches with bimetallic balance wheels your destiny will be to always have to true them. Typically there almost always out of flat or they been squeezed which has undesirable timing consequences and really screws up the poise. Plus typically American pocket watches have just had a lot of undesirable repairers over the years. Joseph Bulova School of Watch Making - Unit 2 balance wheel truing.pdf -

Get a piece of brass plate stock and mark on it where the indicating pins on the balance cock are, and drill them out. Then mark out where the screw would go, then drill and tap it. Then do as nev said, and bend the cock gently. In my opinion, shimming is an unacceptable repair, as its only a timesaving method. Too many bad previous repairs I've seen, I'd rather do it right the first time. Maybe that's why I have the clients watch now, and not the repairman who shimmed the balance. -
What makes you think that your meter needs to be restored does it have a problem? Unfortunately I don't have time to do this but I'll have to come back to the discussion and restore the links because it looks like the links up above are broken and I think they do exist they are just not pointing to where they need to point Then it's good that you gave the number there's actually two separate meters I believe is a 600 and a 700. The preferred approach today is not to restore but to modify with the simplest modification to change the meter to working with silver cell batteries which have a higher voltage than Mercury cell batteries. But a preferred approach would be to make use of the meter movements because that is a very nice analog meter which works really well for tuning fork watches and to produce a variable voltage power supply to use with your very sensitive microamp meter. I did find the missing links from up above their down below and on one of the links if you poke around far enough you will find the schematic for your meter but just in case. Is Then the link to how to properly phase with silver cells although what's interesting is that Bulova actually did check their watches at a much higher voltage. In a case here's one of the ways the phase at a higher voltage Which is I believe one of the broken links up above https://www.accutronwatchpage.com/accphs.htm Here's a webpage where someone modifies their meter which is a wild guess is probably the same person who drew the schematic up above based on his name and the initials on the schematic https://www.accutronwatchpage.com/700meter/700meter.html I really hate websites that do not link to their home page but here's the homepage L notice that both links above are actually on this website https://www.accutronwatchpage.com/

One thing that I struggle with is visualising sizes without seeing it, yes I can get out and tape measure but I would prefer to see it in person. The toolbox is smaller than I thought but will suffice, mops etc currently at work, will add tomorrow. -
mike your skill have constantly improved from the start. Manipulating tiny coils is just another level of improvement, must say its painstaking. When you feel ready to attack the next tiny coil, be confident your dexterity 🧐 is practically on the improve and you will get proficient at it, and come to give good advice. Best regards.
