Nokia Brings Self-Winding Watch Concept Into the 21st Century

Some of you might remember the days when self-winding watches were common. These watches were great. Instead of winding a stem or a battery to power watch gears, all you needed to do was walk around or swing your arm (or just the watch) to power the watch. What could be easier? It looks like Nokia is bringing that old concept into the 21st century by actually generating electricity instead of simply gear motion.
