It's really not a good Idea to wind are reps at the crown,best to use the swirl method. I think It's a good idea to give the main spring more time to build power. I would spend about five minutes swirling the watch then try to start the(stop watch) chronograph by pushing the top pusher,wait for the stop watch hand to go past the 12,maybe to the 5,then push the top pusher to stop It,then hit the lower pusher to reset. BTW the 20 40 60 sub dial Is your running seconds hand. It would help to read up on automatic movements,A7750 etc,there is a ton of Infomation here. Hope this helps,It has worked for me In the past,good luck. Mike
