I am relatively new to this forum and have been exploring the russian watches section so far (since I just bought a rocket N1!). But i have developed an interest in vintage watches. Here is one I am contemplating buying. However, I cannot make up my mind if it is an authentic piece and worth the money. My suspicion is that it is an old movement in a later case. Also, i have not managed to find out how old the movement/ case are. Could any of you knowledgeble people clear these doubts. Thanks in advance.
