The top smartwatches that debuted at the 2017 Consumer Electronics Show included the Casio WSD-F20, Misfit Wearables Vapor and the Garmin Fenix 5 series. Apple released on September 22, 2017 their Apple Watch Series 3 model which offers built in LTE cellular connectivity allowing phone calls, messaging and data without relying on a nearby smartphone connection. 
The headline features are the new ECG monitor that unlocks the ability for serious heart health monitoring. It's been FDA cleared, so the feature can be used to detect heart rhythm irregularities - however, it's only in the US only for now. There's also a new fall detection mode that can let users access Siri to contact emergency services or a emergency contact. Apple's new smartwatch offers groundbreaking features and an improved design that makes it the standout option for iPhone owners right now.
But your phone will play an important part if you do get a Fitbit or Garmin device with the aim of tracking your activity. It will be the place where your health data is synced to, you can tinker with your tracking settings and review your progress. There’s also a whole ecosystem of health apps that plug into tracking devices, combining them with exercise and diet advice - MyFitnessPal, Runtastic and Strava are three of the most popular ones worth checking out.
Smartwatches are still a very new thing to a lot of people, and for good reason. You don’t absolutely need one to get through the day, and some of the best smartwatches are much too expensive for many folks out there. With that said, they are good for a lot of things. They can provide you with an easy way to get information, allow you to dismiss or reply to new messages without having to pull out your phone, and much more.
The launch of Samsung's Gear S smartwatch was covered by the media in late August 2014. The model features a curved Super AMOLED display and a built-in 3G modem, with technology writer Darrell Etherington stating on the TechCrunch website, "we’re finally starting to see displays that wrap around the contours of the wrist, rather than sticking out as a traditional flat surface." The corporation commenced selling the Gear S smartwatch in October 2014, alongside the Gear Circle headset accessory. At IFA 2014 Sony Mobile announced the third generation of its smartwatch series, the Sony Smartwatch 3 powered by Android Wear. Also, the Fashion Entertainments' e-paper watch was announced.
Being able to customize the watch faces and layouts, made the Series 3 a shoo-in for our list of best smart watches. Much like you can customize the homescreen on your iPhone, you can change the layout of apps and even display the weather. While you can’t opt for third-party designs, you do have 12 different watch faces to play with. Tinker with color schemes, add or remove widgets (called “complications” on the app), and decide whether you want to have all twelve faces available on your watch (we always like having options), or cut back.
For deeper integration with your Android phone, you can give Google's Wear OS platform a try with Fossil's $275 Q Control touchscreen smartwatch. It lacks GPS and support for NFC payments, which is why the Gear Sport is a better fitness-focused smartwatch for Android users, but Fossil's Google Assistant integration and stylish design make it a solid contender. However, smartwatches with Qualcomm's new Snapdragon Wear 3100 processor start shipping in October, so you may want to hold off until we put them to the test.
