    Vintage ZentRa watch issue!

    Hello everyone, I've an old vintage ZentRa hand winding mechanical watch with 144 movement 17 Jewels. But I can't find anything about it. Besides, I opened the crown using it's screw down system. Now I can't put the crown closed anymore turning the screw reverse way. I don't know what exactly happen. It would be nice if anyone can help me about this matter and also if anyone can upload the movements schematics. Thanks a lot. Here is the photo.

    Hi, your movement is an Otero 144, some spec details here: bidfun-db Archive: Watch Movements: Otero 144, although you may also wish to post your query on the Watchmaking forum.
