If an 8500 movement is completely out of power, how many turns of the crown make a full power reserve?

Curious as to what would be needed to get my AT with the 8500 to it’s full 60 hour power reserve.

Count the turns until you ear the “click”?

I tried this before when I got my PO 8500. My POs power reserve exceeded 60 hours, around 64-66hrs when fully wound. It was 100 to 120 turns if i remember correctly but may be more than that. However, try to “feel” where the point of resistance would be somewhere within the stated range and slightly lessen the force you apply when turning until you reach a point where it doesn’t turn further. If you had experience with handwound watches, I’m sure you know what I’m pointing at. Good luck.
