The automatic mainsprings have a slipping bridle which means they automatically slip when fully wound such that the auto mechanism can continue to wind them up non-stop.
You can usually sense when they are wound as far as they go because the feeling through the winding crown changes. It’s hard to say how many many winds due to differences in gearing. Could be 10,20, 30 turns at a vague guess.
For an auto like this with manual wind, you will want to give it a few winds if it is starting from cold, because the time keeping will not be great when the balance is swinging with a weak amplitude. Give it ten twists of the crown and you should be fine.
