our smartwatch gets a sporty twist with a comfortable black silicone strap and lightweight nylon and aluminum 41mm case. it keeps you wise to the time and comes equipped with tools to stay stylish (you can match the watch face to your outfit) and ones to stay organized, on the go or on the couch. powered with Wear OS by Google, it lets you download apps, track activities, monitor your heart rate, access google assistant, make contactless nfc payments and set personal goals. you can also get calls, messages and app alerts, toggle between function-centric screens and control music. the device is voice-activated (hello!) and pairs wirelessly with both iPhones® and Android phones. Wear OS by Google is a trademark of Google LLC. touchscreen smartwatches require a phone running Android OS 6.0+ (excluding Go edition) or iOS 10.0+. supported features may vary between platforms.
