The RC-1000 Wrist Terminal was the first Seiko model to interface with a computer, and was released in 1984.[10] It was developed by Seiko Epson and was powered by a computer on a chip.[12] It was compatible with most of the popular PCs of that time, including Apple II, II+ and IIe, the Commodore 64, IBM PC, NEC 8201, Tandy Color Computer, Model 1000, 1200, 2000 and TRS-80 Model I, III, 4 and 4p. The RC-20 Wrist Computer was released in 1985, under the joint brand name "Seiko Epson".[13][14] It had a SMC84C00 8-bit Z-80 microprocessor; 8 KB of ROM and 2 KB of RAM. It had applications for scheduling, memos, and world time and a four-function calculator app. The dot-matrix LCD displayed 42×32 pixels, and more importantly, was touch-sensitive. Like the RC-1000, it could be connected to a personal computer, in this case through a proprietary cable. It was also notable in that it could be programmed, although its small display and limited storage severely limited application development.[10] The RC-4000 PC Data graph also released in 1985, was dubbed the "world's smallest computer terminal".[10] It had 2 KB of storage. The RC-4500 (1985), also known as the Wrist Mac, had the same features as the RC-4000, but came in a variety of bright, flashy colors.

The Charge 3 works continuously throughout the day to track steps, distance, calories, floors climbed, and heart rate—the standard array of activity data. Fitbit has been tracking these metrics for so long, without making many significant updates as of late, that they are business as usual on the Charge 3. I appreciated that most of the watch faces available for the Charge 3 show your real-time heart rate, either in a corner or at the bottom of the rectangular display. I like being able to glance down and know my pulse.

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.


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
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]
The Sport’s built-in fitness features do a decent job of motivating you to move more, tracking a Fitbit-like set of metrics: Stairs climbed, steps taken, and minutes active. It reminds you to get up every hour or so and suggests stretches and movements you can do at your desk if you’re stuck there. While the Sport can track your movement and exercise, and start doing so automatically, it is not accurate enough for dedicated runners or cyclists (who should get a GPS running watch instead): Influential fitness gear tester Ray Maker (aka DC Rainmaker) clocked “the worst GPS track accuracy I’ve ever seen on a run” wearing the Gear Sport. We didn’t see quite the same entirely-different-street discrepancies in biking tests, but the Sport is nevertheless not a competitive training tool, providing only a rough guide to distance and speed.
A smartwatch is a wearable computer in the form of a wristwatch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides for management and telemetry (such as long-term biomonitoring). While early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing, 2010s smartwatches have more general functionality closer to smartphones, including mobile apps, a mobile operating system and Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth or USB headset. Some models, called 'watch phones' (or vice versa), have complete functionality of a typical smartphone using LTE technology.[1][2][3]
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.

Many smartwatch models manufactured in the 2010s are completely functional as standalone products.[6] Some serve as being used in sports, the GPS tracking unit being used to record historical data. For example, after a workout, data can be uploaded onto a computer or online to create a log of activities for analysis or sharing. Some watches can serve as full GPS watches, displaying maps and current coordinates, and recording tracks. Users can "mark" their current location and then edit the entry's name and coordinates, which enables navigation to those new coordinates. As companies add competitive products into the market, media space is becoming a desired commodity on smartwatches. With Apple, Sony, Samsung, and Motorola introducing their smartwatch models, 15% of tech consumers[7] use wearable technologies. This is a dense market[clarification needed] of tech consumers who possess buying power, which has attracted many advertisers. It is expected for mobile advertising on wearable devices to increase heavily by 2017 as advanced hypertargeting modules are introduced to the devices. In order for an advertisement to be effective on a smartwatch, companies have stated that the ad must be able to create experiences native to the smartwatch itself.[8]

I go for a middle-of-the-road approach—I enable alerts for most of my installed apps, save for ones that are niche (mostly shopping apps that alert me to coupons) or ones I don't use regularly. All alerts make the Charge 3 vibrate and show the message on its screen, and all past alerts live in the notification drawer that you can access by swiping down from the top of the Charge 3's display.
A smart watch is nice to have and it can be a neat buffer when deciding if you want to answer an incoming call or let it go to voicemail. Smart watches with apps for fitness and travel are also a lot more convenient in some cases than having your smartphone. However, if you prefer to use your iPhone for these and other activities, you probably won’t get much more out of a smart watch.
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.

Finally, Wear OS has a problem that’s seemingly random and hard to understand: “Can’t reach Google at the moment.” Having tested at least a dozen Wear OS watches, we can say that an unexplained failure when using voice commands is the most common negative trait for all of them. It’s impossible for the layperson to understand which part of the watch-to-phone-to-Internet relay is falling down, but it can happen at any time, even right after you’ve used the watch to do something else successfully. When Google Assistant is made the center of Android watches, not being able to reach Google Assistant lowers the value of that watch considerably.

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.
The Apple Watch Series 4 is now on sale, and it's the best smartwatch you can buy right now. The redesigned device, which starts at $399 for the GPS model and $499 for the cellular version, is the best smartwatch you can buy. It has a larger display and slightly bigger case size while retaining the same rounded square design the watch is known for. Even more importantly, Apple received FDA clearance for a new electrocardiogram feature that can take a 30-second EKG and diagnose atrial fibrillation.
