These two ways of navigating are formalized in pilot training (VFR).
The first one involves landmarks, and the training consists of finding good ones. They need to be highly visible, not ambiguous, and preferably referenced on maps. Following highways is a good strategy.
The second, called dead reckoning, uses the watch and compass. With knowledge of your airspeed, wind speed, and heading, you can estimate your position after a set amount of time.
Usually, a combination of the two is used: dead reckoning between landmarks.
