This is to differentiate watches you have to wind. It's automatic winding rather than manual winding. It's lingo that has stuck around since watches became a common item. All watches were manual winding at first. Then the automatic winding watches came out. Then the quartz battery. We still have all these types of watches but to differentiate they're called quartz, automatic, manual.
