These Poljot's are good looking chrono's in my book, they're kind of on my long list but if one pops up at the right money.... So I'm very much looking forward to following your progress on this Simon so I can refer to it when I eventually score one.
I have the Okean variant dial of this watch. The Russians did an unabashed copy of the Valjoux 7734 for the 3133 movement and mine had a Valjoux part directly swapped into it no probs. Cousins UK for parts.
If it makes you feel any better my movement had been messed up too. I think the Russian military serviced them with WD40, brute force ignorance. It means you have a genuine Russian watch when they’re that badly maintained 😜
I'm interested to see the result of this resto, I have been trying to get hold of a Swiss style chrono to pull down and see how they work, trouble is they are always too expensive for my purpose, it would actually be cheaper to buy an Alpha with a Seagull movement than a clapped out Swiss watch.
The Seiko 6319 seem so simple in comparison with the Swiss chrono.
The chronograph driving wheel separates from the third wheel and will allow you to clean the jewel properly. It's a friction fit and it's worth buying one of these if you plan to be working on more of these movements.
Does your watch have any kind of shim to fit between the crystal and the inner rotating bezel? Mine came with a heavily bodged crystal that was basically no good, once the AM crystal was fitted it developed a rattle which appears to be the inner bezel moving up and down and rattling against the crystal. The thinnest of rubber gaskets stopped the rattle, but also stopped inner bezel from rotating. In my online research I remember seeing a stripped down one with a very thin metal shim that should be inserted. Can I find one? Can I heck.
