For a healthy movement after a full winding (40+ full crown turns) you do not need to wind a 32xx caliber for weeks or months, if you wear the watch daily. I tested that for a period of 64 days, timekeeping was perfect.
See "How to obtain excellent timekeeping over a period of several months" thread:

PS: of course it does not harm to wind your watch movement from time to time, but it is not mandatory for good timekeeping; rest position overnight and temperature are more important than frequent windings.
