Hi, I dropped the crown wheel screw from an omega 625 and spent three hours looking for it to no avail. Does anyone know where I could find a spare? I've searched on eBay extensively but it's looking like I might need to buy a complete movement to replace this part. I'm also aware that two versions of this screw exist, one with 3 lines which is left handed and one with 1 line which is right handed. The one I'm missing is the left hand version. If it helps, this movement is based on the zenith 30.5

I recently found a vintage Pobeda wristwatch in my basement, model 1980-1989. Sadly, it is very old and not maintained at all, maybe since the early 1990s. It is mechanical, so I tried to wind it, but of course it couldn't wind. There is a resistant when I try to do it, so I opened its back and checked what's going on. It appears to me, that the Crown Wheel and the Ratchet Wheel are either too tight, or not lubricated/rusty or whatever the reason may be. Also I found out that when I move the watch around, it winds itself, as if it is an automatic one (it certainly does NOT have any rotor, so that is weird). So I was wondering what has to be done, at this moment I don't have any repair tools. If someone can at least give me a direction as to what has to be done, I could search for some tools. I'm not so worried about the watch itself, although it has a sentimental meaning to me, but am curious to find out what the reason for the problem is.
