Found the following section on the page "A deeper look at the SII NH35A watch movement":
"Now all of this is “interesting” but not very useful to anyone other than budding watch geeks who might still be enthusiastic about picking up an Invicta 8296OB or a Vostok Amphibia for cheap which are powered by the SII NH35A."
I can't recall ever having seen a genuine Vostok Amphibia with any other movement that the Vostok cal. 2415/16. The Buyalov watches on meranom.com have this SEIKO movement. Is this perhaps a misunderstanding on the behalf of the writer of the article, or did I miss something?
The 2415 automatic is a much later movement.
I'm not aware of any Vostok Amphibians with any other than these movements either ...... but maybe I missed something too .....

I think it is a misunderstanding.
Perhaps this is a rumour.
Perhaps the Buyalov models have caused confusion, although the article was written before the Buyalov models were introduced.
I have written a short response to that article in the comment section to help clear the confusion.
During the past two years or so, my number one interest has been to learn about and practice watch servicing and repair. So far, I’ve been working on the most common Vostok 24XX movements (2409/14/15/16b) where my journey began with the help you comrades, the rather impressive Poljot cal. 2614.2H and some Swiss calibres such as ETA 1080, AS 1203, OMEGA 601, UNITAS 6498. Next in line is the classic ETA 2824-2 (can’t wait for it).
I must have been tinkering with watches in a previous life as I feel such contentment and enjoyment handling tools and tiny parts. Anyway, I always seem to miss and return to the Vostok 24XX movements. Their value for money is just incredible and to me they are always going have a special place in my heart.
Anyway, the point of this post is to share the disassembly and assembly pictures I took of a Vostok cal. 2414 that I’ve just serviced (a Komandirskie with a rather different dial). Since a while back I’ve started to carefully document these steps by taking pictures for any, to me, new (or not yet documented) movement that I work on.
There aren’t any fixed rules for how to take a watch movement apart or how to reassemble it and it can be done in many ways, but I’ve learned an established practice, devised to make the process as safe and painless as possible. For example, this practice means that the balance assembly (as we all know is the most sensitive part of the movement) is removed as soon as possible, that the motion work is removed before the train wheel bridge to make it safer and easier to remove the cannon pinion, and so on. The pictures follow this established practice, but of course, don’t cover tools, techniques, and lubrication, but should be helpful to anyone already having acquired those skills. To follow along, the pictures, stored on OneDrive, should be sorted by name.
I also have a set of pictures showing my assembly steps (pictures taken during disassembly!) of a Vostok 2416b. I never really meant to share those pictures so that’s why they also include coloured arrows to suggest points (but not quantity) of lubrication. (white arrow = Moebius 9010, blue arrow = Moebius 9501, red arrow = Moebius 9104, yellow arrow = Moebius 9415). Going through those lubrication points now I have some small objections, but good enough, I guess!
Anyway, I hope that my pictures will contribute to this excellent thread and to promote our love for Vostok watches!

I really like these posts, I'm not a watchmaker, but I do find it very interesting

@VWatchie; Very well done and very good pictures too
A small remark on picture 43 & 44 keyless, the very small intermediate sprocket. Have you ever noticed that the internal bore has on one side a slight chamfer? That chamfer has to go on top. Failure to do so may cause problems and interfere with the cover-plate, not always but I had too many. Since I noticed the chamfer and placed it the correct way, never again. If unaware, you have a 50% chance to assembly it correctly
Perhaps we can combine forces again and help Matt in his Vostok repair section. I did sent him already some basic & specific Vostok tutorials of how to change hands, how to change a dial and how to change a date-wheel; this to help the "Modders" among us.
These tutorials haven't been posted jet, but Matt said he will do so shortly.
Anyway, nice to see you here again
Those tutorials will be greatly appreciated by many I'm sure! (I would have "killed" for them when I was new!) and if I can contribute with my pictures (I believe they can be downloaded), or something else I'd be glad to. Perhaps my "Differences between Vostok 24XX parts" posts over at watchrepairtalk.com can be of some use? Please feel free to use!
Thanks, and nice to be here comrades!
Sometimes using the precise description, although technically being correct, can, depending on the audience, be confusion too. I guess you know that all too well
Yes, the chamfer of the little intermediate wheel has to face up, towards the keyless "coverplate" / setting-lever-spring, facing you.
On the internet there is lots of information on how to do certain aspects of watch repair, but according to Matt there is a great need for very Vostok specific. Matt is the coordinator for these tutorials but has, as I understood, at the moment some other issues.
I guess we have to wait a little and as soon as I hear from him, we'll team up
Looking forward to it!
