Help with rotor on A7750

[craustin1]

Hi guys, been here for a bit, but have not posted much. I do need some help, maybe someone can chime in. The rotor on an A7750 has fallen of my watch. I took the back off, and can see the rotor was not attached, and there was a small ring, possibly a retainer ring loose as well. What is needed to get the rotor reattached? Any help greately appreciated, thanks.

Sounds like the bearing is still attached to the movement, which should be held in place with one central screw. That ring you mention is indeed a retainer ring, you need an oscillating weight removal tool for refitting it correctly, but if needed, you can get away with doing it with some tweezers.

Yes, the bearing is still attached. I will play with it see if I can get it on there. Thanks
