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. 
Why we like it: Apple Watches are the best smartwatches overall because they make it easier than any other wearable device to interact with the messages and notifications relayed from your iPhone. The Series 1, specifically, has all the features most people need at a reasonable price. It looks better than most smartwatches and fitness trackers, on wrists both large and small, thanks to two sizes and an array of finishes and bands (both official and third party). While not every major iPhone app has an Apple Watch partner app, many do, and most respond quickly and are optimized for the watch’s small screen, unlike many of the apps available for Android watches. And the Series 1 Apple Watch does a good job of independently tracking most kinds of workouts where accurate distance tracking isn’t vital,1 and encourages non-workout fitness (like standing and moving every hour). We also like that the Apple Watch lets you easily make contactless payments using Apple Pay, and if you own a Mac, you can unlock it by just getting close to it with your Apple Watch.
The MetaWatch M1, like the Cookoo 2 and Martian Notifier, is a basic smartwatch. It shows alerts for texts, e-mails, social media updates, calendar appointments, weather, and Caller ID, and can control your phone's music app. The notifications are configurable in terms of what you are alerted to and how: whether via a vibration or on the watch’s display. Also built in are a timer, a stopwatch, and an alarm
Get connected and stay up-to-speed with Misfit smartwatches, a family of complex timepieces that have been designed to help you live, work and play a little smarter. If you're looking for a smartwatch that can do far more than just tell you the time, consider a timepiece crafted from premium materials that showcase both its strength and its style. With a variety of customization options, you can personalize any Misfit smart watch to suit your unique personality, and then configure it to stay in-sync with your day-to-day activities.
Apple has continued its focus on its health focus with the Series 4. In addition to being able to detect a fall, this new Apple Watch introduces three heart-rate tracking features that will be available later this year. It lets you know if your heart rate is too low, it can detect irregular rhythms (which may indicate atrial fibrillation), and most impressively, it serves as an FDA-cleared electrocardiogram.
Having a miniature computer strapped around your wrist is no longer a pipe dream. The Apple Watch and other options from popular manufacturers, like Fitbit, Samsung, LG, and Fossil, have been gunning to craft the best smartwatch. Now a few years more mature, the smartwatch market offers more than ever, whether you’re after a particular style, iOS and Android phone compatibility, or just a bunch of features.
Unlike the Apple Series 3, you can get third-party watch faces along with the default options. Many of these third-party faces also come with customizable widgets so you can manage layout without cluttering up your watch. From the homepage (which displays the time and date), you can twist the bezel to access fitness tracking data, like steps taken and calories burned, check the weather, change the song you’re listening to, or use any number of custom widgets.
But the Ionic, the first of Fitbit's devices to include an SpO2 monitor, came out more than one year ago. It's frustrating to hear about exciting features that are "coming soon," when "soon" ultimately means not weeks or months, but years. While I understand it takes time and effort to develop features like this (especially if Fitbit hopes to pursue medical device clearance or approval from the FDA in the future), I don't think Fitbit should hype features that it isn't ready to let users put to the test.
The SmartWatch 2 is a streamlined version of Sony's first smartwatch (which went on sale in 2013) with a number of new features. The SmartWatch 2 has a thin bezel; it's almost all screen, which gives it a modern, sleek look. You choose from one of two strap designs, black plastic or black stainless steel, or you can swap those out for a leather strap in one of seven colors ($20 each). We tested the model with the plastic strap, which is light and flexible and can fit close to your wrist.
When we compared the storage space of the Samsung Gear Sport with the other contenders, it didn’t have the most. With 4 GB — only a quarter of what you’ll get with the Apple Watch Series 3 GPS — you will have to manage your apps so you don’t run out of room. If you like to carry all of your music with you and you have an extensive library, you might run out of space with the Gear Sport.
Garmin, known primarily for its GPS and fitness devices, has taken one step closer to full-featured smartwatches with their Vivoactive 3 Music. This model doesn't run on Wear OS (Google's increasingly-popular OS for wearables), but it does offer thousands of free apps, watch faces, and more via Garmin’s ConnectIQ store. The Vivoactive 3 Music also comes preloaded with 15 sports apps to monitor your progress whether you're running, swimming, lifting, or doing yoga — because, at its core, Garmin is still all about fitness tracking
Our top pick for most people is the Apple Watch Series 4 with GPS (starting at $399), which has a huge display, ultra-fast processor, Raise to Speak Siri, fall detection and a built-in electrical heart rate sensor for taking on-the-go electrocardiograms. It also runs watchOS 5, which makes the watch even more useful with automatic workout-tracking, offline podcast playback and a Walkie-Talkie voice chat feature.
