Watchlists are--like all pages generated by MediaWiki software--static HTML. The display of their contents does not change as the content on the backend changes and new revisions are only viewable once the user refreshes the page or otherwise calls for it. Watchlists and certain other special pages (e.g. Speical:RecentChanges or Special:Contributions/User:FOO) should use some method of dynamically refreshing a la Gmail's inbox using XMLHttpRequest.
