I heard they have concluded that it was to no fault of the track that this kid died. Give me a break. Given all of the crashes already, I can't imagine that no other athlete is going to go over the side wall when all is on the line in competition
The Asian 6497 movements are prone to clicking on winding. Ziggy can tell you all about it. It isn't that big of a deal unless it starts slipping when you are winding it. Then you replace the movement.
The more Swiss the movement, the smoother the wind. Also a freshly serviced Asian will wind smoothly in my experience.
