Got these older Vostoks yesterday. All not running but had easy problems to fix, luckily for 4 out of 9. One Amphidia and the rest Komandirskies. I love them, they're pretty reliable thus far.

 

I've been having a problem keeping the seconds hand in on a couple. Any tips? Is there a special way to make them stay?

I'm guessing your movements are the same as my Amphibia, in which the seconds pinion is held in place by a weak cantilever spring.  Pressing the seconds hand in place simply pushes the shaft down against the spring so that the seconds hand doesn't engage properly on the shaft.  You need to brace the seconds pinion from the back to prevent it moving when you attach the seconds hand.  I just use my finger to brace the pinion but I daresay there are other more proper ways to do it.

Kayman is exactly right. Here is a photo of what we mean. The brass spring has, as you can see, a round-shaped end which has to be supported. I put a piece of rod in my mini bench vice and supported it on that.

Yeah i thought that would hold it but i guess not. Many thanks for the tip. Also i seem to have problems with the balance wheel stopping. The pivots look fine, is it just a jewel possibly broken?

I'm surprised at their robust and fairly accurate movement. Quite a bang for your buck workhorse. 3 are keeping excellent time and I'm having trouble regulating a few gaining 5mins/day at least. It's annoying there's no quick set date but i don't care. My morning isn't complete without winding these babies up. It's a successful thing when i wake up and they're (most of them anyway) are right around the exact time... It's a wonderful thing to fix these with your own two hands and see how reliable your work is.

Any guess on the date of manufacture on these? Obviously the Amphidia is pre-89 I'm guessing 70's/80's and the Komandirskies early 90's? I'm quite sure they're all 2414 movements too correct?

@Mattaphysics: It's not until now that I see your post. Did you get them all working?

It's a bit hard to see on the pictures whether they are pre-1990's or after the collapse of the Soviet Union. Of all the watches it seems that the Amphibian has a bit more sought after dial and bezel, but this depends also on the condition and what's written on the bottom of the dials. CCCP is of course before the collapse, but then you also had the military issued watches (3AKA3). To make matters more complicated, mix in watch-soup the fake CCCP dials .......

If they are all hand-wound, the movements are 2409 (without date) or 2414(with date complication), not sure if the Amphibian could have the even older 2209 movement?

Anyway, they are all quite simple to repair....... that was also the general idea behind these watches. You have enough training material and eBay is full of spare-parts :) Some parts between the 2409 and 2414 are interchangeable, but some are (sometimes) not .... I think VWatchie wrote something about that .....

For the date change you first advance the time over midnight. To acheive the quickset you should alternate the hour hand forwards (between 1 and 3) and backwards (between 11 and 9 o clock)...

      Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy

      What are these Seitz B-Jewels?

      By Jon · Posted

      I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!

      Diagram for 6497 motion works

      Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.

      So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
