Hey everyone! 

I bought my first automatic watch, a 7s26, a little over 5 years ago. Recently, I picked up some vintage Russian watches and fell in love. I'd love to be able to buy old Russian treasures on the cheap and service them myself! But first, my plan is to start with Nickolas Hacko's 7s26 tutorial.

Welcome here.

Nick takes some steps that are debatable in his incomplete tutorial (calendar re-assembly wasn't ever done). I suggest that you look first at the "servicing walkthrough" on this forum, and Mark Lovick's videos on YouTube.

Wow, thank you for the heads up! I'll definitely reconsider my decision to go with Hacko.

Don't get me wrong, he's surely a good watchmaker and commendable for having published his work a long time ago already. But the 7S26 is so popular that you can easily find multiple sources of information and learn even from the small differences that there are.

Nothing wrong with Russian watches.actually they are quite good.if you get one that hasn't been too severely abused.I would tell you to start on them..simple no date versions manual wind.then move to the more complex.

      Any tips to correct a sloppy error?

      By rjenkinsgb · Posted

      Two pins or screwdrivers angled out slightly, pressing through from the barrel centre from the opposite side so they contact just clear of the hole in the lid? eg. Strap pin driver needles or similar.

      That's a good idea - shrinking down the nut and wrench size from the old casebook trick!

      Movement holder made with 3D printer

      I missed this earlier. The dial isn't going into the holder, it should sit proud of it. This is what I am currently using which I print for each different movement.

      Setting lever spring

      By Neverenoughwatches · Posted

      I didn't think pulling to set position would work harden the spring, in that position it is stressed where the arm starts. By work hardening i meant rapid polishing at that point, a bit like polishing a pivot work hardens as it compresses the steel. I doubt polishing by hand would achieve much in that respect though. Its finished, arm polished up mostly at the join to the bridge's main body. I'm ok with it, the screw holes aren't great as i had to open them up by redrilling and positioning it was difficult, I'm not much use with a loupe, opening up with a file might be a better option for me or i could just use the correct drill size 😅. And the detent is way too deep, i had to guess that with the stem release out of position and sat on top, but i only took one measure and went for it, no slowly slowly catch your monkey 😅. First go I'm happy , well sort of, it works and thats a big thing for me, next one will have a bit more finesse.  Anyone thats interested, after filing, i used a 2000 grade home made diamond  micro file and then 20 micron film, the film is much better than wet and dry, more stable to use and doesn't shed cheap grade grit everywhere , then auto polish on a sponge pad.

      I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong.
