What is the difference between a self-winding and a manual-winding movement?
The difference between these two movements is the way in which the watch is wound up. Manual-winding watches must be wound by hand every day. Self-winding watches are wound by an internal rotor, which responds to wrist movements. Self-winding watches usually have a power reserve of at least 40 hours and therefore have sufficient energy reserves to maintain a stable rate when the watch is not being worn (e.g. overnight).
