Click on the WATCH button at the bottom-left corner of the window. If you are viewing the mobile page, make sure to switch to VIEW FULL SITE (at the bottom of the page) before.

To see the recent changes on your watchlisted pages go to Special:Watchlist on your wiki. That also should be linked on the bottom bar.
