How do you rotate your multiple watches?

[nyyankees]

I know I've seen it discussed before but for those of you who have 3 or more watches how do you rotate them? I'm trying to decide if I should spend cash on a 3 or 4 watch winder or keep just handwinding when I pick the one I'm going to wear. Maybe I should just rotate by week or even month. I'm curious what you guys do and how often you change up what your wearing and whether or not you use a winder to keep them ready to go.
