OK Captain, now, put the crystal back in .. but don't do it from the backside, it snaps into place from the front of the watch ok ... so looking at the watch, snap the crystal back into place in the ring from the very front of the watch facing you .. this keeps it away from the hands. If the crystal presses on the hands or even slightly touches it, it will stop.   I did the same thing with my 992. Once I put the crystal in from the front. You will here it pop in, gentle pressure, ran perfect as it was no longer pressing on any hands ... give that a try and wind er up
