I'd vote for manually winding it.
I bought a winder and quit using it. For the modern pieces that could run constantly and I wouldn't care it's just not all that hard or time consuming to set everything; besides if you are a anal freak like me the time after a couple of days will have to be adjusted anyway on most watches. For the vintage stuff that takes more effort to set up I decided I didn't want to add the mileage. The winder now sits there just holding watches on display.
