CRAP! The watch started to act funny tonight after I used the chrono and let it ran for a couple of minutes. It then completely stopped. I opened her up and found the clutch spring loose inside...
Argh....

nicely done!!! mine I took to the store today, the watchsmith said one of the screw or spring was loose and dropped to somewhere in the movement.....he didn't want to fix it for me, guess I will have to go to one of the modders on the forums.
Sounds a lot like what happened to mine! If you have some mechanical skill and a some watch tools, look at my article from the here above post, you probably just have to remove the balance wheel assembly. Make sure to hack the movement by putting in in time setting mode before removing the balance wheel bridge.

The rotor was floating and I found the small o ring floating under it. Can any one identify? I just removed both for now and the watch seems to work fine
I did not find any. How small are they and do I risk further damage if I open the case and shake it upside down to see if they fall out?Looks like the bearing cage seperated. Did you find micro ball bearings in the movement?
