...up to my knowledge there are no black dials with Cyrillic letters...Experts, please correct me if I'm wrong, but I believe the black dial was available under the brands "Poljot" and "Sekonda" and only with latin letters. There are (rare) versions of the Poljot in cyrillic, but so far I have only seen cream colored dials and not with the paddle hands. Cyrillic and black dial is a combination that I have not seen so far. But my interest in Soviet horology is very young, so I might be mistaken.
did you find one with the cyrillic letters?It is Strumanskie, and it is not so nice like 3133..
