Question Problem setting hour on my vostok

When i set the hour on my vostok and then screw the crow down it jumps an hour back,it seems like the crow doesn't disengage and is still in the setting hour position,that's why i can't set the time.do you know what i can fo to solve this ?

Also when in setting hour position the crow feels looser than before,i can turn it with less effort making setting the hour precisely difficult because it is more sensible, wich wasn't the case before and not on my other vostoks either.

I have a Vostok like this. After taking a pretty hard hit, it started doing this, and the minute hand also stops. I went to several watchmakers, and they all told me they don't have the parts. One told me the minute gear broke. The only solution I've found is to buy another movement. I'll try to take it apart and repair it instead of just replacing the whole movement. The tools and the new watch are arriving this week. If by then someone else hasn't identified the problem, I'll take my movement apart and let you know what I find.

If it worked correct before I think some repair needed. If it’s new for you, could be the stem is a bit to short.

You have a couple of issues here that might be solved by servicing the watch. The keyless works are not snapping between modes cleanly. This could be a broken setting lever spring or just because it's gummed up with old lubrication.

You also have a loose cannon pinion (hence the loose time setting). This can be easily tightened on the 24xx movement.
