I think you need to check it is actually broken first. Vostok Amfibia use a rather clever clutch so the crown is only engaged with the movement when changing the time. They are meant to wobble around like they are broken. Sent from my iPad using Tapatalk Pro

Hello guys I've been renovating quite a few 1960s Seikos recently and a couple have shown very scattered traces on the timegrapher and generally ratty running after cleaning. All three responded to a new escape wheel very well. Being unable to see the wear using normal magnification I decided to try one of the £15 USB microscopes available on fleabay. They are too light, the software is hit and miss but glue it onto a heavy base and they will do the job. The difference between a good and bad wheel became obvious. The square corners get rounded off by the fork pallet jewels and precision is lost. The first two shots are from a worn 6602B and a 7625A Auto. Note the rough finish but 50 years ain't bad - neither watch back showed any servicing marks and were bone dry. The third shot is also a 6602 but it's a good performer - note square edges. The last is from my new baby - King Seiko 4402. Very different quality. Three lessons. 1. These devices are fine for simple close examination. 2. Don't neglect oiling the escape pallets - it's tricky but worth the effort 3. Once you've handled a part with your fingers it needs cleaning again - it's horrifying how many skin particles appear.

Thanks Roberto, I also love the dial color. To repaint the bezel I read the best is to use enamel for toy models, fill the numbers and let it dry. Then with a peg wood I can eliminate the excess, am I correct? I'm a little scared i would create new "scars" in the bezel i just polished...

+1 @rogart63 and @Sopgeo. This is a design characteristic of the Amphibia and also the most common query / concern of newbie Amphibia owners. Just google Vostok Amphibia wobbly crown and you will find many examples as below; http://forums.watchuseek.com/f10/question-about-boctok-amphibia-crown-wobble-462400.html Somewhere on the net there is a really interesting article about the development and evolution of the Amphibia design which explains a lot of its idiosycracies, if I can find it again I will post a link. These are actually great watches and represent truly excellent value for money.

Hello watchlovers! My name is Peter, I am a hobby watchmaker for 25 years now, still learning...... My interest for mechanical watches started in the beginnig of the 90ties, when eastern people came to Germany and sold russian watches on fleamarkets. My first mechanical watch was a Poljot alarm watch, very nice, new an chaep! I dont´t remember, guess it was 20.- D-Marks, this time... This was just the beginning! Every weekend I went to the Fleamarket nearby, buying one or two new russian watches. (Sometimes more!) One day, you can imagine, one of this watches broke..... Damned! What is the problem? You must know, I am a vehicle machanic! So I opend the watch and had a look! OMG, a lot of tiny screws and stuff! Next day I got me some screwdriveers and tweezers for this, started to dismantle the watch. Ok, useless to say: this was the very end of this watch! :-) But, again, i took the next one....... And in went back to life! Great! From this day my skills got higher and higher, my workbech got bigger an bigger! Now I am able to repair all watches and chronographs! Ok, I can do not all, but I got many friends, some are hobbists like me and some are professional watchmakers! They give some help and so do I! In all this years I collected some watchparts and other watchstuff, my store is really huge! My dear wife helps a lot to manage all this! I you need some watchparts,ask........ That´s me! :-) Sorry for my poor english!

That is probably the gasket around the movement that is holding the movement in place. The black one . Remove that and the movement will come out. Could be hard as bakelite so could be destroyed when taking it out but there is no other way.

Congratulations. You have achieved something that many watch repairs would never be able to do. You really do have watchmaker skills.

Hey guys, FYI, here is the result. Not so bad in the end...
