Pebble (watch) was an innovative smartwatch that raised the most money at the time on Kickstarter reaching $10.3 Million between April 12 and May 18, 2012. The watch has a 32-millimetre (1.26 in) 144 × 168 pixel black and white memory LCD using an ultra low-power "transflective LCD" manufactured by Sharp with a backlight, a vibrating motor, a magnetometer, ambient light sensors, and a three-axis accelerometer.[47][48][49][50][51] It can communicate with an Android or iOS device using both Bluetooth 2.1 and Bluetooth 4.0 (Bluetooth Low Energy) using Stonestreet One's Bluetopia+MFi software stack.[52] Bluetooth 4.0 with low energy (LE) support was not initially enabled, but a firmware update in November 2013 enabled it.[53] The watch is charged using a modified USB-cable that attaches magnetically to the watch to maintain water resistance capability.[49] The battery was reported in April 2012 to last seven days.[54] Based on feedback from Kickstarter backers, the developers added water-resistance to the list of features.[55] The Pebble has a waterproof rating of 5 atm, which means it can be submerged down to 40 metres (130 ft) and has been tested in both fresh and salt water, allowing one to shower, dive or swim while wearing the watch.[56]
Some smartwatches have robust offerings of apps, either preinstalled on the watch or available for download in an app store. Apps can be as simple as a timer or stopwatch, or can control your smart-home devices, switch up your music, or provide turn-by-turn directions for walking or driving. In our testing and everyday use, however, these watch apps rarely offer a great experience. But there are some exceptions, including some fitness apps and apps that track things like water or food intake.

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]
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.

The build is fantastic with IP68 waterproof and Corning Gorilla Glass DX+, and the display looks great with a resolution up to 360 x 360 and Circular Super AMOLED tech. On the larger model, the battery sports a capacity of 472 mAh, which powers the snappy Exynos 9110 Dual core processor. You can choose between Silver, Midnight Black, or Rose Gold color options, and the bands are interchangeable to match your style. But most importantly, with the Tizen-Based Wearable OS 4.0 that Samsung has optimized to work with their proprietary controls and apps, this will be the perfect sidekick to your Samsung phone.

To round off the Gear Sport’s positives, it has very solid battery life (almost never less than 50 percent of the battery remaining after a full day), it can play offline Spotify playlists (even for free accounts), and if you have a Samsung phone, it integrates easily with most of the apps you have installed there. The Gear Sport is easier to set up with a non-Samsung Android phone than previous versions of the Gear watch, too. It still requires the installation of at least four apps and some regular updating, but it’s not the hour-long trial-and-error of other Gear watches we’ve tested, working reliably in our testing.
Wear OS’s chief problem, as we see it, is that it relies too much on input from swipes, taps, and other finger gestures. On a largish screen, such as on our top pick, this is less of a problem, but on smaller devices, trying to hit just the right button on the screen is like playing a very small version of Duck Hunt. The Apple Watch, by comparison, makes most of its buttons screen-wide rounded rectangles, which are easier to hit. On newer watches with three buttons, Wear OS also doesn’t utilize the physical controls beyond the home display (watch face), where they serve as shortcuts to apps or a list of apps.
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 Charge 2 was one of Fitbit's most popular trackers, so the company stuck with the winning formula with the Charge 3. If you're at all familiar with the Charge 2, you'll notice that not much has changed in the updated device—it's still a rectangular tracker hugged on its short edges by two parts of a band. Fitbit updated the connecting mechanism that lets you switch out the bands on the Charge 3, making it easier to press the black sliver of a button on either end to release the device's current band. The new band snaps right into place without any extra effort.
How frustrating. I really -like- the idea of a smart watch... but it's so hard to find the right one. I'm not an exercise freak so heartrate monitors etc are useless to me. I really like the design of the Samsung watches with their bezels to control it, but the Tizen OS with it's limited apps puts me right off. The Access Grayson watch is beautiful, but the lack of NFC is a deal breaker for me - Google Pay with the convenience of a watch is part of the reason I'd buy one. I don't need to be able to put a sim in it... that's what my phone's for, but GOS would be nice for when I travel, and as a motorbike rider some level of waterproofing is a must. Guess I'm waiting for the next round of watches to see what's on offer.
In order to find the best smart watch, we looked at text and call features and, of course, design. We dug into tech reviews to separate must-haves from perks. Then, we brought in 19 smart watches to test for call responsiveness, text-ability, app accessibility, and general ease of us. In the end, three watches stood out for their reliable connectivity, gorgeous interfaces, and easy navigation.
