The Samsung Gear S3 was our prior pick for Samsung phone owners because of its smooth dial rotation and interface. But it was notably large, with a 46 mm face, and the Frontier model was half an inch thick, notably bulky even for a smartwatch. The Gear Sport, our runner-up pick, is less bulky, less expensive, less overtly masculine-styled, and provides most of the same features, minus the LTE option.
In 1998, Steve Mann invented, designed, and built the world's first Linux wristwatch,[15] which he presented at IEEE ISSCC2000 on 7 February 2000, where he was named "the father of wearable computing".[16] See also Linux Journal,[17] where Mann's Linux wristwatch appeared on the cover and was the feature article of LJ Issue 75. Seiko launched the Ruputer in Japan - a wristwatch computer with a 3.6 MHz processor. It was not very successful, since instead of a touchscreen it used a joystick-like device to input characters (much like high scores in arcade games), and the small screen with a resolution at 102x64 in 4 greyscales made it hard to read large amounts of text. Outside of Japan, this watch was distributed as the Matsucom onHand PC. Despite the rather low demand, the Matsucom onHand PC was distributed until 2006, making it a smartwatch with a rather long life cycle. Ruputer and onHand PC applications are 100% compatible. This watch is sometimes considered the first smartwatch since it was the first watch to offer graphics display (albeit monochrome) and many 3rd party applications (mostly homebrew).
Of the scores of Wear OS by Google (also called Wear OS, and formerly Android Wear) smartwatches that function nearly the same, the Fossil Q Explorist and Fossil Q Venture are the ones we recommend for most people. Similar models that differ mainly in size and design, these two Fossil watches offer style and band options for the widest range of tastes while performing as well as (or better than) anything else out there. They handle notifications and your responses without delay, provide all-day battery life, swiftly handle voice transcription and Google Assistant questions, and provide casual fitness tracking. Their buttons and screens are responsive. They look and feel like good watches, too, which is something we think most people want from a smartwatch at this point.
In the same year, Microsoft announced the SPOT smartwatch and it began hitting stores in early 2004.[30] SPOT stands for Smart Personal Objects Technology, an initiative by Microsoft to personalize household electronics and other everyday gadgets. For instance, the company demonstrated coffee makers, weather stations, and alarm clocks featuring built-in SPOT technology.[31] The device was a standalone smartwatch[32] that offered information at a glance where other devices would have required more immersion and interaction. The information included weather, news, stock prices, and sports scores and was transmitted through FM waves.[30] It was accessible through a yearly subscription that cost from $39 to $59.[31]

The Q watches do not have built-in GPS or heart-rate sensors, and aside from one model (the black silicone strap Explorist), they are not made for heavy exercise tracking. The watches’ IP67 rating means that they’re dustproof and ready for rain, and that they can survive a short dunk in water less than 3 feet deep. For tracking your walking, movement, light bike rides or occasional runs or hikes, though, the watch does fine.


The Fitbit Versa is nearly a full smartwatch, but the way it handles notifications prevents it from being a pick. Fitbit’s sleep, step, and workout tracking features beat our current picks’, and in our testing the Versa regularly lasted for four or more days between full charges. It lacks GPS, which the Ionic has, but it has a lower price as a result. You can choose from a decent variety of band types, although the bands are an odd 23 mm size (rather than a standard 22 mm), and slot in at an angle, making it hard to know if an unofficial band will fit. You can cache Deezer or Pandora radio stations to the Versa’s 2.5 GB of reserved space, control the music on your phone (after reconnecting your watch in “classic mode”), or transfer your own music to the watch, though it’s a tedious process involving a computer and cable. Where the Versa falls short is in working with notifications from your phone. The notifications pile up, and it can be a hassle to clear them; most notifications don’t expand to show more text; and though a software update has given you quick replies to select from, you’re limited to five of them. Like the Ionic, it’s more of a smartened-up fitness tracker than a fitness-savvy smartwatch.
Samsung treads between smartwatch and fitness tracker, also packing in a heart rate sensor along with that GPS and its much-improved Samsung Health software. There's also the option of LTE (coming soon), if you wish for an untethered connection, with a standalone speaker for taking calls on the watch. It's now waterproof, too, adding swim tracking skills that are on par with the Watch Series 4.
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.
It has all the same core fitness and sports tracking as the Series 3, including built-in GPS and a swimproof design. You can also expect improvements in run tracking and new supported activities like yoga and hiking. It comes packing LTE once again so you can take it out sans iPhone and still make/receive calls, get texts and all other notifications you would on your phone. A new speaker should also make Siri chats and phone calls sound louder and clearer.

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.
Then your typical exercise activity will determine which model is the best fit. You can expect to pay $1500 - $350 for a fitness tracker. If you are simply interested in hitting your 10,000 steps a day, an entry-level Fitbit will do the trick for around $150. Garmin has fitness trackers designed specifically with runners and cyclists in mind, giving you accurate tracking of biking and cycling distance covered using GPS. They’ll cost more as a result - $350 - $800.

Tizen is a Linux-based operating system for devices, including smartphones/tablets, in-vehicle infotainment (IVI) devices, smart TVs, laptops/desktops and other platforms. Tizen is a project within the Linux Foundation and is governed by a Technical Steering Group (TSG) composed of Samsung and Intel among others. Samsung released the Samsung Gear 2, Gear 2 Neo, Samsung Gear S, Samsung Gear S2 and Samsung Gear S3 running Tizen.[86]
I have the new version Samsung Galaxy watch 46mm. It is excellent. I do not have to use spotify premium to play music. I can simply add tracks (and images too) saved on my Note 8 phone. Bixby can open the apps without turning the bezel. The battery life is not 6 days as advertised, if used all day to make calls, text, listen to music, play games, check emails, read the news, search the internet, etc, then the battery lasts at least 3 days before recharging. There are several free watch faces available through the Galaxy app. This watch can also be used to make sos calls which can be preset for 911 or any contacts you wish to add. Then these contacts can call you back on low volume mode and listen for an hour. You can use this feature with a timer so if you accidentally activate it, you have time to turn it off before it makes the call. Adding a GPS app to this phone can allow you to take a screen shot of your location and send it if in a crisis. Of course the google app for navigation is also available for travel. You can use a wifi connection without your phone, if you turn off bluetooth and select wifi connection to your watch via phone. There is no need to buy the most expensive Samsung Galaxy with the built in sim. Also samsung pay is available on the watch. Of course it has Accelerometer, Gyro, Barometer, HRM, Circular Super AMOLED (360 x 360) Full Color Always On Display, Corning® Gorilla® Glass DX+. There is also a feature that tells you when to take deep breaths while it count the duration of inhaling and exhaling. This is great when you need to stay calm. The workout features are better than on previous Samsung watches. You can monitor calories, caffeine intake, water intake, track your sleep. You can swim with this watch. There is a water lock feature. Once you are out of the water you can expel water from the speaker by tapping a button. This watch has several other functions but It’s too much to write in a quick review. Of course you can add a security pin to your watch, use locator to find your phone or vise versa. You check youtube for more of the features. Samsung doesn’t have everything listed in specs. I’m still keeping my Ferragamo and Versace watches but I think I’m selling the rest of watch collection. The Samsung Galaxy watch has all of the features I need and changing watch bands is easy. I still recommend buying a screen protector and a tpu/silicone case or shell in case you drop your watch. Some sellers are offering a 2 year guarantee which includes accidents but I have the 1 year Samsung warranty. I would love this watch more if it had a nano sd slot. Specs are 768MB RAM and 4GB Internal Memory.
Many major phone apps have Wear OS counterparts, or at least most apps that make sense to have a dedicated watch app. You’ll likely find yourself using most watch apps less than you might think, but they are sometimes convenient for avoiding a phone retrieval. I use regularly use the Nest app for my home thermostat, Keep to take down a quick voice note, PocketCasts to control podcast episodes and playlists, and Stronglifts to time and track workouts. But I use these on my watch mostly when my phone is not at hand; none is easier to use than its phone version. As noted, most apps on your phone will provide notifications that can be acted upon through your watch. For the apps that you do use, the Q watches’ screen (identical to most of the Fossil group watches’ screens) is responsive enough to work with tiny buttons pressed by big fingers.

Inside the Charge 3 are an accelerometer, gyroscope, optical heart rate monitor, and an SpO2 sensor for tracking blood oxygen levels. The Charge 3 is the third Fitbit device to include an SpO2 sensor, following in the footsteps of both the Fitbit Ionic and the Versa smartwatches. However, currently the SpO2 monitor lies dormant inside all of these devices as Fitbit hasn't made use of it yet.
Our 19 contenders all promised to give us some distance from our phones by notifying us of incoming calls and texts. But we found that some smart watches were much slower than others at letting us know we had a call. It turns out the quality of the bluetooth connection determines how quickly you’ll be notified, with our worst performers only registering the call with two seconds to spare before diverting to voicemail (yes you, Montblanc) while others simply failed to display any calls at all.
