Yesterday, I accidentally dropped my watch. It's a Noobmariner Ceramic Rolex GTM II with asian 2836 clone. When i opened, i saw the rotor was not fixed, it's out of the center screw (that is fixed in its place), moving free into the watch. When i try to put in its place and close the watch, another time the rotor fall out. How Can i fix in the center, please? The watch runs whitout problem, but the automatic function is loose.
