Morphology
self-winding = winding (transparent) = self + wind + ing
Formation is a straightforward prefixation of 'self-' to the participle 'winding', meaning 'winding itself', which learners can derive from known parts.
Etymology
Self-winding comes from putting together self ('by itself') and wind ('to turn'), like when you 'wind' a watch by hand. So a self-winding watch turns its spring by your movement and you don't need to wind it by hand.
