Answer 1

Springs! You would have to wind your watch to keep it working. I’m not a horologist but there would be a spirally wound spring connected to gears that would spin at the correct speed to keep the watch displaying the correct time. Every so often you’d have to wind up the spring like you wind up those little toy cars that drive across the floor.
