Track your runs with GPS and altimeter. Pair your watch with compatible gym equipment. Apple Watch Nike+ is swim proof, so you can take a post-run dip in the pool. You can make phone calls, send messages, and get notifications. Train with Audio Guided Runs. And listen to Apple Music and Apple Podcasts—Apple Watch Series 4 lets you do it all right from your wrist. There are new Nike watch faces and two Nike bands: The Nike Sport Band with compression-molded perforations for breathability and the Nike Sport Loop is woven with a special reflective thread.
