When a user is logged in, you will see a link in the sidebar entitled "Watch this page" (on non-dynamic pages). When you click on that link, you add the current page and the corresponding talk page to your watchlist.
You can access your watchlist by clicking on the My watchlist link in the sidebar.
The watchlist basically functions as a personalized recent changes page, just for articles that you select. It gives you a list of all watched pages, reverse-ordered according to the time each page was last edited. The default cutoff for the watchlist is currently three days for users with less than 1,000 pages in their watchlist, and 12 hours for users with more than 1,000. (This is a default setting that cannot be changed by the user.)
Each line in the watchlist provides the usual details about the last edit: the date and time, if it was a minor edit (or not), the difference between the current version and the previous one, the history, the editor's user name, and the edit summary.
