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)...

      Down the rabbit hole!

      By fnick · Posted

      Hi all Thought I'd show my small and trying to keep under control watch collection! Apart from the Enicar all were under £12! At least if I destroy them in the process then I won't be too worse off. A few pics to start off with First of all my first attempt. A Thuya pocket watch. It was only running face down and would stop when vertical. So now it still works face down and only slows down when vertical so at least an improvement! 😄  I only have a generic watch oil at the mo so that won't help but I'm hoping to get some more appropriate oils in a couple of months for my birthday. I did have to get a crystal for it since it didn't come with one. It didn't look as though it would friction fit (and I don't have a crystal press in any case) so I glued it to the case with PVA. So far so good. Next up above are a sekonda and citizen automatic. Both non runners. Both with broken balance wheels amongst other things. I'm hopeful the citizen will start when I get the new one I ordered but the sekonda is being kept for spares and trial of new techniques. And finally the Enicar and the timemaster. Both running when I got them. I wanted to get running watches so that at least I stood a fighting chance of still having a running watch after the service! It was all going well on the Enicar until I dropped the balance wheel during reassembly...😔. Unfortunately they are quite expensive to get so for now I'll won't do anything with it but I would like to fix it at one point. The timemaster is still running (yeah!) but I managed to break a dial foot during the deassembly. First repair attempt failed so now I am looking at soldering it back on... So there we go. My initial foray into this great hobby. Thanks for sticking with this tale so far.  I'm hoping that once the balance wheel arrives for the citizen I will be able to say I bought a non runner and fixed it! So fingers crossed. Thanks for looking, Nick

      Like losing Ranfft. That was a wake up call. We took his website for granted. Miss him terribly.

      Its 4 o'clock in the morning here in the Uk, i cant sleep, i dont sleep, not much ever really. My brain never shuts off to rest, I'm just a constant thinker, i have to be very tired to be able to sleep,  i guess eventually it will be my undoing and my health will suffer because of it I'm sure. But while I'm here i want to get as much out of life as i can, and give as much as i can, to help,maybe to make a difference to someone's life if that is within my capability,recent events have made that need even more clear to me. I'm not sure where I'm going with this or why i bring it up , or if its relevant to want i want to talk about its just in my head right now. What i do want to talk about is something thats been on my mind for ages. I like to be prepared,  I'm not fond of surprises because surprises take control away and i am a bit of a control freak at times. This forum, Our Forum if i can call it that, is here because of two reasons. The guy that created it and keeps it funded and the people that joined it.  Without either, it would not exist, and lets face it one day it won't ( I'm a realist and i talk about things others dont or who are afraid to in other words folk that dont particularly prepare for the inevitable). How many of us visit here regularly ?  How many among us almost depend on the forum as a way of socialising because they are stuck at home and how many of us has it become part of a daily routine to check in and see if they can offer advice or get help with something they are working on or just to have a chat and engage in some banter. The members here are in the thousands and thousands have disappeared over the years many had just a fleeting visit. But there are a good few of us that know each other quite well and visit regularly. I dont know about you but i wouldnt want to lose that communication with you all, in all honesty it has become an important part of that side of my life and helps to feed my passion for all things watches. Some of you may think differently and thats ok, some of may stop and think # what would i do " Without Our Forum " #

      Gamblin Gamsol for cleaning?

      Naptha appears to be a general name and its content can be varied depending upon what it's specific use is. Lighter fluid as an example can be light or heavier also with other ingredients to help it burn. Try sesrching for benzine ( as opposed to benzene which is linked to causing health issues ) . There are other fluids such as ethanol that you could try and also methylated sprirts, mostly ethanol with a small percentage of methanol added. Experiment with any new chemical to see how quickly schellac dissolves in its presence. I have tried a few things but hexane is not one of them, i understand it does evaporate very quickly.  Be sure sure to check out any safety data on chemicals you try. Toxicity of fumes and flash point information, ultrasonic machines can heat up fluids even without a heater function. And of course always ask here for personal opinions when trying a new substance.

      What tools does ebay have to offer this week.

      By GuyMontag · Posted

      I have that set and really like it. I prefer that crystal holder over the one that came with my Bergeon claw tool and any time I use the claw I use this one instead of the Bergeon one, just an additional bonus with this tool.
