We've just completed lab tests on six of the newest smartwatches to hit the market. Three run on the very promising Android Wear operating system, which Google created specifically for wearable devices—the LG G Watch, Samsung Gear Live, and Motorola Moto 360. We also tested several basic models: the Martian Notifier, Cookoo 2, and MetaWatch M1. And we included reviews of nine smartwatches that we tested previously; all are still available, and we updated their prices. Find out what we liked and didn't like about the six newly tested models.
"Sport watch" functionality often includes activity tracker features (also known as "fitness tracker") as seen in GPS watches made for training, diving, and outdoor sports. Functions may include training programs (such as intervals), lap times, speed display, GPS tracking unit, Route tracking, dive computer, heart rate monitor compatibility, Cadence sensor compatibility, and compatibility with sport transitions (as in triathlons). Other watches can cooperate with an app in a smartphone to carry out their functions. They are paired usually by Bluetooth with a smartphone. Some of these only work with a phone that runs the same mobile operating system; others use a unique watch OS, or otherwise are able to work with most smartphones. Paired, the watch may function as a remote to the phone. This allows the watch to display data such as calls, SMS messages, emails, calendar invites, and any data that may be made available by relevant phone apps. Some fitness tracker watches give users reports on the number of kilometers they walked, hours they slept, and so on.
When it comes to smartwatches, one size most definitely does not fit all. The best option for you depends on a number of factors, including the smartphone you use; whether you want strong activity-tracking features; your budget; and your aesthetic tastes. For example, many people prefer a smartwatch with a round display because it looks more like a standard wristwatch than a piece of tech. You'll want to take all these factors into consideration when you begin the search for the best smartwatch for you. So whether you’re looking for something appropriate for dinner parties or back-country trails, high-end, budget or something in between, we’ve tracked down the best smartwatches on the market this year.
In June 2000, IBM displayed a prototype for a wristwatch that ran Linux. The original version had only 6 hours of battery life, which was later extended to 12.[20] It featured 8 MB of memory and ran Linux 2.2.[21] The device was later upgraded with an accelerometer, vibrating mechanism, and fingerprint sensor. IBM began to collaborate with Citizen Watch Co. to create the "WatchPad". The WatchPad 1.5 features a 320 × 240 QVGA monochrome touch sensitive display and runs Linux 2.4.[22][23] It also features calendar software, Bluetooth, 8 MB of RAM and 16 MB of flash memory.[24][25] Citizen was hoping to market the watch to students and businessmen, with a retail price of around $399.[25] Epson Seiko introduced their Chrono-bit wristwatch in September 2000. The Chrono-bit watches feature a rotating bezel for data input, synchronize PIM data via a serial cable, and can load custom watch faces.[26]
Since the early days of modern smartwatches, we’ve sought to test as many relevant models as we can and recommend the watches that do the best job of making a smartwatch convenient and useful. We test Wear OS watches by wearing them while they’re connected to Android phones. Whenever possible, we ask other people to try out our potential picks to get an idea of how others react to a watch’s size, style, interface, and other features.
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.
Bottom line: Some fitness trackers work equally well with an iPhone or Android device, but some smartwatches are built to pair with Android phones so you won’t enjoy full functionality and pairing on an iPhone. The Apple Watch only pairs with the iPhone so is off limits to Android users. Your existing phone choice will play an important part in choosing a smartwatch.

The company claims that the SpO2 monitor will help its devices look for signs of sleep apnea and other breathing problems, potentially great features for devices that are meant to be worn 24/7. It'll be used primarily in Fitbit's forthcoming Sleep Score Beta, which further analyzes sleep quality using heart rate and breathing data. Starting sometime this November, users with devices that only have heart rate monitors can get a "sleep score" after each night's sleep. Those with an Ionic, Versa, or Charge 3 will presumably have better data thanks to the SpO2 monitor collecting breathing data.

The base model is crafted from polished stainless steel with a premium calfskin leather band. Other models are available with a titanium casing and alligator leather straps, but they do up the cost quite a bit. All models have a 46mm casing that is 12.5mm thick. Battery life is rated at a day and the watch is IP68 water/dust resistant.Pricing for the Summit starts at a lofty $870 and goes well up from there. Currently, the only place to buy the watch online is via the outlet Mr. Porter, but it’s also available anywhere Montblanc smartwatches are sold in retail locations.


While internal hardware varies, most have an electronic visual display, either backlit LCD or OLED or Hologram.[4] Some use transflective or electronic paper, to consume less power. Most have a rechargeable battery. Peripheral devices may include digital cameras, thermometers, accelerometers, pedometers, heart rate monitors, altimeters, barometers, compasses, GPS receivers, tiny speakers, and SD cards, which are recognized as storage devices by many other kinds of computers.

Like previous Gear watches, the Gear Sport uses a rotating bezel and two side buttons for most of its navigation. This works better than you’d think by looking at it, and it’s a boon to those who wear gloves for part of the year. In fact, we actually prefer this approach to Wear OS or the Apple Watch: Rotating through your home screens, notifications, lists of apps, or messages happens at remarkable speed for a tiny device. The screen is 1.2 inches and 360 pixels in diameter, but it’s brighter than our pick’s, and it looks decent enough while displaying most content, though text isn’t as sharp as on the Fossil screens. The watch itself is not small, at 43 and 44 millimeters wide and tall, respectively, and 11.6 mm thick, but it’s nowhere near as beefy as our prior pick, the Gear S3.
Samsung Gear S3 Frontier: Until we see what Google can pack into a smartwatch with its long-awaited Pixel Watch, the best smartwatch for Android users is the Samsung Gear S3 Frontier. It pretty much has everything a user with an Android phone needs in a smartwatch - GPS, heart rate monitor, water resistance, near field communications, an always-on digital display, messaging alerts and app support. I don’t see a real need to opt for the 3G version yet, which would untether you from your phone completely but adds around $100 to the price. ($549)
The primary differences with the Classic versus the standard include, first off, that this model lacks LTE. That, however, does mean that the Classic is built from a more premium “Titanium Grey” shell which has a bit less sporty look. A leather band is also installed out of the box rather than the silicone one found on other models. Pricing on the Huawei Watch 2 Classic is a bit higher than the standard model, asking $369 from retailers such as Amazon and Best Buy.
If you’re trying to decide which one is right for you, allow us to help. The Versa is smaller and looks good on most wrist sizes, while the Ionic is probably best for large wrists. The other main difference is GPS connectivity — the Ionic comes with built-in GPS, while the Versa does not. However, you can pair it with your smartphone if you don’t mind bringing it with you on a run. 
Apple Watch is crisp, beautiful, high-resolution screen that’s smaller than an Oreo cookie. No surprise, Apple knows what they’re doing when they design a home product. Much like the other additions to the Apple suite, the Series 3 is sleek and stylish. Everything from the navigation to the screen layouts has been optimized to utilize the space given rather than be constricted by it.
