The good news is it's super simple: The chronology of the movies matches up with the release order, so you can watch "Jaws," "Jaws 2," "Jaws 3-D," and "Jaws: The Revenge" in that order.
But the best way to watch "Jaws" might be with a live orchestra playing that iconic score. The New York Philharmonic plays for four movies a year at Lincoln Center. Almost every showing is sold out.
