Valjoux 7750 problem

Recommended Posts

Whenever I work on a watch that has the valjoux 7750 chronograph movement I’m always faced with one problem - removing the centre chronograph second hand!

Its always so tight on that the collet will break off or the hand just generally ends up damaged, I’ve tried numerous times with different sized levers and presto tools but still can’t seem to do a great job of it. Anyone any tips on getting it off?
