The RC-1000 Wrist Terminal was the first Seiko model to interface with a computer, and was released in 1984. It was developed by Seiko Epson and was powered by a computer on a chip. 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". 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. The RC-4000 PC Data graph also released in 1985, was dubbed the "world's smallest computer terminal". 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.
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.
The Nixon Mission is a rugged 'action' smartwatch, and we really like it. The durable casing can take a bashing, while the Qualcomm Snapdragon Wear 2100 keeps things ticking inside. It runs Android Wear, but also comes with some useful pre-installed apps which track real-time surfing and snowboarding conditions. It's water resistant to 10ATM (roughly 100m), and best of all, it comes in Orange.

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. 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. Bluetooth 4.0 with low energy (LE) support was not initially enabled, but a firmware update in November 2013 enabled it. The watch is charged using a modified USB-cable that attaches magnetically to the watch to maintain water resistance capability. The battery was reported in April 2012 to last seven days. Based on feedback from Kickstarter backers, the developers added water-resistance to the list of features. 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.
Out of a vast field of similar watches, we picked the Q Explorist and Q Venture because of their middle-of-the-road prices, wide availability, and variety of styles. These two models are flagships for the Fossil Group’s collection of 14 style brands producing more than 300 planned smartwatches. This means that if you find a smartwatch from Diesel, Skagen, Tag Heuer, Kate Spade, Movado, or another Fossil-connected brand that fits your style better, you should feel free to buy it, because it will have roughly the same internal hardware as our picks.
The top smartwatches that debuted at the 2017 Consumer Electronics Show included the Casio WSD-F20, Misfit Wearables Vapor and the Garmin Fenix 5 series. Apple released on September 22, 2017 their Apple Watch Series 3 model which offers built in LTE cellular connectivity allowing phone calls, messaging and data without relying on a nearby smartphone connection. 
As a piece of hardware, the Gear Sport is probably the best smartwatch we’ve used. It’s not stylish, it has deep flaws in its voice software, and it’s only a beginner-level fitness tracker. But if you want a smartwatch that has a bit of fitness motivation—and if you also happen to have a Samsung phone, or might get a deal on a bundle of phone and watch—the Gear Sport is a good option.
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.
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 LG G Watch was the first one we tried that uses Google’s Android Wear OS (the Moto 360 and Samsung Gear Live do as well). It includes Google Now, the company's Siri-like "intelligent personal assistant." Say “OK Google,” and you can do Google searches, compose texts, and make requests of your watch (“Show me my steps” or “Set an alarm”). Google Now also offers up a stream of "cards" on the watch's face, with information it determines is relevant to you. If, for example, the card tells you how many minutes it would take you to get home from your current location, you can click on the card and get specific traffic and navigation information.
Smartwatches are still a relatively new electronics category, but these devices are poised to hit the mainstream. This year we saw major players such as LG and Motorola throw their smartwatches in the ring, along with Samsung, Sony, and a host of smaller companies like Pebble and Martian. And Apple finally confirmed its entry, the innovative Apple Watch, expected to arrive early in 2015.

Google confirmed to Tom's Guide that the company won't be releasing its own Wear OS smartwatch this year. The news comes after months of rumors that a Google-branded Pixel Watch running on Qualcomm's latest processor would be launched at Google's October hardware event. Instead, Google plans to focus on adding features to Wear OS on the software side and support the companies who are currently making Android smartwatches. Google's hardware event is Oct. 9.
