Winding problem

 

It depends on how much the crown move in anticlockwise direction.

I have tried to wind up a few manual winding PP in an auction preview, and found that for most manual watch, the crown will actually move back slightly in anticlockwise position (i.e. a few degree) after I wind it up in clockwise position and let go the crown.
But the power reserve of 24hrs seems to be a bit short.
The 5170J should have 65 hr power reserve.
Have you wound it up fully, till the point that the crown cannot be further wound?
Certainly it will reassure you by asking the advice from a PP service center.
Cheers
Henry
