If you can live with the limited apps available, the Gear S2 is one of the best smartwatches available.
Memory 512MB RAM, 4GB internal storage // Connectivity Bluetooth 4.1, Wi-Fi, NFC // Sensors Accelerometer, gyroscope, heart rate monitor, barometer, ambient light // Battery 250mAh // Dimensions 42.3 x 49.8 x 11.4 mm (Gear S2), 39.9 x 43.6 x 11.4 mm (Gear S2 Classic) // Weight 47g (Gear S2), 42g (Gear S2 Classic) // URL www.samsung.com/my predecessors; there isn't a camera and you can't make phone calls via speakerphone. What you do get: message notification, information apps, fitness tracking, playing music via the internal 4GB storage through a paired Bluetooth wireless headset, and respond to messages or trigger voiceactivated actions using a built-in microphone. The watch vibrates but there's no speaker.
Still, Samsung has done a really good job of streamlining the UI and making it intuitive and easy to use. Turn the bezel to the right from the main watch face and you can scroll through information widgets like your physical activity for the day or the weather, and turn it to the left to see your notifications. Notifications can be filtered and are interactive, just like on Android Wear. You can respond to incoming messages with preset responses, voice dictation, or tap out a response on a miniature keyboard.
Two buttons on the side of the watch also aid navigation, the top one is a back button, while the bottom one acts as a home button and brings you back to the watchface.
The biggest drawback to the Gear S2 is the lack of apps. Running on Tizen restricts it to a limited library of compatible Gear apps, and many of the big names are missing right now. Nike has its own watch face, and there's an ESPN app for sports scores, but you won't find Facebook, Twitter or Uber here. One move Samsung has made towards getting more developers on board with Tizen is making the S2 compatible with any phone running Android 4.4 KitKat or newer with at least 1.5GB RAM.
Both the standard Gear S2 and the S2 Classic are equipped with a 250mAh battery. On both watches, battery life was better than expected, and you can easily go two days of light use without a recharge.
Overall, the Gear S2 is welldesigned, stylish, innovative, elegant and easy to use. It has the best display I've seen on a smartwatch and it has, by far, the most natural and intuitive way of interacting with your smartwatch so far. It's the best round-faced smartwatch I've used; but not the best overall smartwatch. The apps just aren't there right now, and without that ecosystem backing it up, it's missing a huge part of the smartwatch experience.
The Gear S2 Classic has a knurled bezel, similar to a diving watch.
