Track your runs with GPS and altimeter. Pair your watch with compatible gym equipment. Apple Watch Nike+ is swimproof, so you can take a post-run dip in the pool. You can make phone calls, send messages and get notifications. 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 exclusive straps: the Nike Sport Band with compression- moulded perforations for breathability and the Nike Sport Loop woven with a special reflective thread.
