Friedhelm Posted November 29, 2009 Report Share Posted November 29, 2009 (edited) hi members, I think I've done a mistake. For reduce the spinning noise of the rotor, I gave it a little watch grease.(A 7750) I removed it and put a little bit grease on the rear side of the bearing. I've tighten the screw handwarm. If I try to wind the watch with the crown it's very hard and the rotor spins. Automatic winding with the rotor seems to be normal. What have I done wrong with it ? Can anybody help me ? Thanks Friedhelm Edited November 29, 2009 by Friedhelm Quote Link to comment Share on other sites More sharing options...
andreww Posted November 29, 2009 Report Share Posted November 29, 2009 You shouldn't really hand wind an automatic movement. I think what has happened is coincidental to your greasing the rotor. What has happened is that the winding gears ha worn out from hand winding. This causes the rotor to spin when winding. You can either use it without hand winding, or service it and have the winding gears replaced. Quote Link to comment Share on other sites More sharing options...
kbh Posted November 29, 2009 Report Share Posted November 29, 2009 Although I'm not an expert but since I just got a watch back from repair that was doing the same thing Ill try to explain. There's apparently two anti-reversing gears or clutch system that are often sticky or dirty. They're not necessarily broken or it's not necessarily from hand winding. Also it's relatively common problem with A7550 movements according to my watchsmith. It was an inexpensive fix for me. Hopefully that's your problem also. There's a tutorial about this problem, I think in Francisco's section. Quote Link to comment Share on other sites More sharing options...
Jkay Posted November 30, 2009 Report Share Posted November 30, 2009 Did you get grease in the two anti-reversing gears? :/ They are the little gears directly below the rotor. Quote Link to comment Share on other sites More sharing options...

I don't think so, but maybe ? The gears looking clean. Thanks Friedhelm Edited November 30, 2009 by Friedhelm Quote Link to comment Share on other sites More sharing options...
FxrAndy Posted November 30, 2009 Report Share Posted November 30, 2009 The part in question is called the reversing wheel and id two gears on top of on another in one direction they stay together and in the other they slip, the parts are not interchangeable with the swiss ones with out a lot of work and Francisco has done a tutorial on changing them and modding the swiss one into Asian Quote Link to comment Share on other sites More sharing options...
Friedhelm Posted December 1, 2009 Author Report Share Posted December 1, 2009 Thank you all for the helpful replies. The watch works perfectly with automatic winding. I think I'm leaving my fingers away, but it's nearly impossible to find a watchmaker in germany who's servicing a rep. Or do you know someone?

nikki6 Posted December 1, 2009 Report Share Posted December 1, 2009 You have one of the best right on your doorstep my friend!! Try Bricollio, I think thats how you spell it, he is in Germany and does most of the servicing for the EU guys. If you can't find him, look for Star69, he has his details in his sig!
