That's the reason why I always make sure that the crown on my SKX007 is screwed into the tube tightly. It's much better and a lot safer to have the SKX007 crown screwed tightly into the threaded tube rather than it being screwed in loosely and for it to accidentally get loose.[/QUOTE] That is one reason the SKX007 is so good & popular. The crown at 4 with case protection is designed just to minimize knocking by accident. Whereas the crown at 3 is prone to being knocked about. A bad position in my book.
