A smartwatch isn’t going to replace your smartphone. The screens are too tiny and they can’t stream Netflix. Plus most smartwatches don’t have LTE, meaning they can’t receive calls or texts when not tethered to your smartphone or connected to wi-fi. But smartwatches do have some advantages. Many effectively make your Fitbit, Misfit or Jawbone fitness tracker obsolete. They show you who’s calling, texting or emailing you without forcing you to look at your phone. And some look pretty cool. Whatever your lifestyle and which smartphone you use, you’re bound to find something that suits you.
Apple Watch Series 2

For the iPhone Owner: The Apple Watch Series 2 is a significant improvement upon the first iteration of the smartwatch. iMessage, Twitter and Instagram all work smoothly, and you can adjust all your HomeKit gadgets from the watch. It has a heart rate monitor to accurately keep track of your fitness metrics, even when your iPhone isn’t nearby. Unlike the Apple Watch Series 1, the Series 2 also has a built-in GPS and is waterproof. The main downsides of the Apple Watch Series 2 are that it doesn’t really look like a traditional quartz watch and that it doesn’t come in an LTE version, so you can’t receive calls or texts without your iPhone. And if you have Android, no Apple Watch, Series 1 or Series 2, will work with it.
Samsung Gear S3 Frontier

For the Galaxy S7 or S8 Owner: The Gear S3 runs on Tizen OS — not Android Wear 2.0 — and seamlessly works with all of Samsung’s apps: Samsung Pay, S-Health, and the S-Voice assistant. Newer Android smartphones, like the Google Pixel or LG G6, can work with the Gear S3, but it’s probably not worth it since not all Samsung apps will carry over. The Gear S3 comes in two models, Frontier and Classic, but the Frontier is a better option, as it’s water resistant and has a built-in GPS. Plus, the Frontier comes in an LTE model, meaning you can call and text people without your smartphone. (Although, a separate data plan has to be set up and it only works with AT&T or T-Mobile.) Other nice features include a 2- to 3-hour battery life and tactile rotating bezel.
