• A little progress of sorts with the hand-winding Vostok Komandirskie.
    I looked under the loupe at the hairspring which seems okay.
    I noticed it was running uninterrupted with the crown unscrewed, so I removed the crown stem and cleaned it up with a cotton bud and isopropyl alcohol.
    Put it back then ran fine for a couple of days on the bench. However out and about on the wrist it stops randomly.
    So I think it will need a strip down, clean, lube and rebuild. Back in the drawer for a bit until I find time to learn how to do this!

  • I have a Sturmanskie that could be a donor watch too if you want another low-risk movement to play with. Same issues as the one you describe - winds fine, keeps good time - stops randomly but a tap on the face will get it moving.
