I've been pleased to see swim-tracking trickle down into more affordable devices over the past few years. Fitbit's Flex 2 remains its most affordable device with swim-tracking features, priced at $60. But the $150 Charge 3, with its big display and smattering of smartwatch capabilities, is for a different audience than those who would gravitate to the tiny, quasi-cylindrical Flex 2. Even if you don't swim often, water-resistance up to 50 meters means users don't have to worry about showering with the Charge 3 or dropping it in the pool by accident.
The new Diesel Full Guard 2.5 has a 47mmx56mm casing which is bigger than most Wear OS watches, and there’s a 1.39-inch display at the center of that. This new refresh of the watch also includes NFC for Google Pay support, a heart rate sensor, and built-in GPS. Diesel also says this watch will last two days on a charge from the 300mAh battery. The watch also has 3ATM water resistance.

The claim to fame on the Ticwatch Pro is battery life. The Pro offers up to 30 days of battery on a single charge. Of course, that all depends on how you use it. Mobvoi’s trick to improve battery life comes with the addition of a layered screen that acts as two displays. One is designed for use when the watch is idle, only showing crucial information such as the time to sip power. Under that is a standard OLED display that delivers the full Wear OS experience.


It doesn't get better than the Apple Watch Series 4. The new slimmer body and bigger screen make it sleeker and more stylish than ever before. The unique modern design works for both men and women. The smartwatch comes in 40mm and 44mm styles to fit wrists big and small. You can buy it in several finishes to match your style and there are dozens of Apple-made and third-party watch bands to make the Watch your own.

In 2003, Fossil released the Wrist PDA, a watch which ran the Palm OS and contained 8 MB of RAM and 4 MB of flash memory.[27][28] It contained a built in stylus to help use the tiny monochrome display, which had a resolution of 160×160 pixels. Although many reviewers declared the watch revolutionary, it was criticized for its weight (108 grams) and was ultimately discontinued in 2005.[29]
If you’d prefer your smartwatch looked more like a piece of jewelry than a small computer on your wrist, you’ll like Skagen’s Falster range. The straps of these slimline watches come in a few different leather or stainless steel options but coupled with the included minimalist watch face designs, they all look sleek and stylish in a way few other smartwatches manage.

When you do switch to the OLED display, you are in TicWatch Pro’s Smart Mode, and you can perform all of the features and functions that are available in the smartwatch. However, switching to the low-power FTSN LCD display puts the watch in its Essential Mode. The nice thing is that when you switch back to Smart Mode. all of the heart rate and steps info gathered by the watch’s Essential Mode are synced up and transferred to the onboard Wear OS. As you might expect, the battery life in Essential Mode can last up to 30 days, while using the smartwatch in Smart Mode cuts that battery life down to just two days.


I’ve worn a smartwatch almost daily for nearly five years as of this writing. I often feel that it keeps me alert to what’s happening, especially for things like texts from my wife and close friends, alarms that a parking meter is nearly expired, or reminders that dinner needs to start marinating or roasting. It has also encouraged me to get moving and take a walk when I’d otherwise stay in place. Sometimes it has made me feel rude, distracted, or overly attached to whatever little blip comes next. It has come in handy on my bike, and it has distracted me when I’m driving my car. Some of this can be better handled through settings and filters, but some of it comes from human nature.
Apple has announced the Apple Watch Series 4. It’s the first real redesign of the wearable since Apple introduced it in 2014, but the changes aren’t so drastic that you won’t recognize it as an Apple Watch. The Series 4 comes with an upgraded display, and you can choose either a 40mm or 44mm model. Even though the screens on the new models are bigger, the overall body of the Watch is roughly the same as previous models, so you shouldn’t notice much of a difference on your wrist.

Apple Watch Series 3: If you are an iPhone user and generally exist in Apple’s ecosystem, it makes sense to get an Apple Watch. The design quality is exceptional and the Watch makes a nice pairing with your iPhone as materials and design elements are common to both. Apple’s Health app covers most of the bases when it comes to tracking your essential fitness and activity indicators - nutrition, sleep, physical exercise, but Apple has gone further with HealthKit, which allows health and fitness apps downloaded from the App Store to share data with each other. Apple has committed to Watch, and its attention to practical and eye-pleasing design as well as useful tracking features is commendable. ($529)
The Explorist and Venture cases are an average thickness for a round smartwatch (at 12.5 and 11.5 millimeters, respectively), with widths of 45 mm and 42 mm, respectively. Neither watch feels too heavy or awkward on a larger wrist, though even the smaller Venture watch is still quite chunky on a smaller wrist. Each model’s battery regularly lasted a whole day in our testing, and the voice-dictation functions are on a par with those of most smartwatches; the same goes for Google Assistant’s accuracy. Both watches and their Google Fit system track day-to-day activity, and although Wear OS apps don’t have quite the buy-in from app makers that the Apple Watch does, you can likely find your favorite apps in Google’s Play Store, and most phone apps provide rich notifications that you can interact with through the watch. Both show signs of good build quality, with thoughtful attention to detail on all surfaces and no cheap connectors or pieces.
In China, since around 2015, smartwatches have become widely used by schoolchildren. They are advertised on television throughout the country as a safety device whereby the child can call in case of emergency. The devices are commonly colorful and made of plastic. They normally have no display unless a button is pushed. These smartwatches have limited capability compared to other smartwatches; their main functions consist of being able to conduct calls, displaying of time, and sometimes have air temperature sensitivity. They cost around $100 to $200 USD.

Bottom line: If health and fitness tracking is your priority, opt for a dedicated fitness tracker that gives you basic time and date information but includes the essentials of health tracking - accelerometer and altimeter, heart rate monitor and GPS chip to track distance and location. Carefully consider your exercise habits to match them to the right fitness tracker.
For a device that gives you more of the functionality you enjoy with your smartphone, you’ll want to opt for a dedicated smartwatch. The leading players at the moment are the Apple Watch for iPhone users and the Samsung Gear S3 for those with Android phones. Apple Watch has its own operating system, Samsung employs its Tizen OS, and a host of other smartwatches use the Google Wear operating system.

Wear OS comes with a focus on fitness features, but unfortunately Huawei managed to simultaneously move too far in this direction and also fall short of it. It doesn’t come with a rotating side button for navigation, which is a shame as we really love the button on the LG Watch Sport. It does, however, come with great battery life and a stellar feature set otherwise.
The era of the smartwatch is upon us – just look at the multitude of colourful straps and elongated or squarish screens people are wearing. From fitness trackers like the Fitbit and Garmin to the Samsung Gear and Apple Watch, there are a host of great options to combine fitness and activity tracking and message alerts on your watch, which incidentally will still tell you the time, along with the weather and even play your favourite music.
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.[72] At IFA 2014 Sony Mobile announced the third generation of its smartwatch series, the Sony Smartwatch 3 powered by Android Wear.[73] Also, the Fashion Entertainments' e-paper watch was announced.[74]
Built-in GPS and a great workout coach make the Huawei Watch 2 a great companion on long runs and intense workouts. You can leave your phone behind, too, thanks to onboard music storage and the ability to connect Bluetooth headphones to the watch. Like the LG Watch Sport, the Huawei Watch 2 has an LTE version, but unfortunately, Huawei isn't selling that model in the US yet.
If you like traditional analog watches and want just a few smart features, the Cookoo 2 might be more appealing than its more full-featured rectangular competitors. Behind its hands is a monochrome display that delivers basic notifications: incoming calls (with Caller ID), missed calls, texts, e-mail, social media alerts (for WhatsApp, Line, QQ, WeChat, Skype, Facebook, Twitter), and calendar alerts. Just bear in mind that it's a very basic smartwatch, with little configurability.
The Huawei Watch 2 was one of the first smartwatches to launch with Android Wear 2.0 (now known as Wear OS), so delivers the handy Google Assistant straight to your wrist. Other improvements include more ways to respond to messages from your wrist, including a new on-screen keyboard. Wear OS doesn’t quite rival Apple’s watchOS for app support, but it has a decent stable of apps you’d expect.

Apple is back with the Apple Watch Series 4, the latest in the smartwatch game that's focused on helping wearers live a healthier lifestyle. Running on Apple’s S4 64-bit dual-core processor and the new WatchOS 5 operating system, it’s twice as fast as its predecessor. Available in two sizes — 40 mm and 44mm — it has a 30 percent larger display than the Series 3 and comes in six different aluminum and stainless steel finishes. New improvements include Walkie Talkie mode and a speaker that is 50% louder than in the Series 3. The microphone has been moved to the watch’s opposite side to reduce noise and create clearer phone calls. The bottom, now made from black ceramic and sapphire crystal for better radio wave transmission, is intended to help with cellular reception and call quality.
Fitbit Versa: The Fitbit is the health tracker for the masses and they have a model for every need. But the best option for adults who do a moderate amount of exercise and just want to keep tabs on their general fitness (ie: most of us), the Fitbit Versa is a great choice. It's an entry-level smartwatch. For more on the Fitbit Versa’s various attributes, read my in-depth review. ($350)
We test every new smartwatch to gauge its design and comfort. If it’s not stylish and comfortable enough to get you from an early morning workout to the office to a night out, you probably won’t wear it every day. Most smartwatches are also fitness trackers, so we put all of its sensors to the test, from step counts to heart rate to GPS (when applicable).
