geestyleed Posted January 26, 2009 Report Share Posted January 26, 2009 Hi guys!. Just a short question. After I haven been searching in the forum I haven't found a good answer. I have three watches with a A7750 mvt(Hublot BigBang, Chopard GTXXL and Porsche Flat6). The rotor of the Hublot and the Porsche is often spinning so fast that I think that this cannot be good for the movement. Does anybody know if that can damage the movement? I'm a bit worried....

freddy333 Posted January 26, 2009 Report Share Posted January 26, 2009 Spinning fast due to inertia is normal on a 7750, but if the rotor spins when the watch is manually wound, then the movement requires servicing. Quote Link to comment Share on other sites More sharing options...
geestyleed Posted January 26, 2009 Author Report Share Posted January 26, 2009 Ah OK thanks! The rotor doesnt spin when manually wound via the crown. Quote Link to comment Share on other sites More sharing options...
Toadtorrent Posted January 26, 2009 Report Share Posted January 26, 2009 Ah OK thanks! The rotor doesnt spin when manually wound via the crown. You can read the threads on the noisy rotor linked in my Noob Guide linked in my signature for more details...and so you don't feel alone.

Shundi Posted January 26, 2009 Report Share Posted January 26, 2009 I recall The Zigmeister stating somewhere that the rotor cannot spin fast enough to damage/stress the click wheels the way manual winding can on a poorly serviced movement. As Freddy stated: the watch should be fine- especially if the rotor isn't spining while you manually wind the watch. Quote Link to comment Share on other sites More sharing options...
