Smart watches are wearable devices that work with a smartphone to deliver messages, emails, and other notifications right to the wrists of users. Because Android is an open source operating system, there are multitude of smart watch manufacturers. Products include the Ticwatch, LG Watch Style, Asus ZenWatch, Huawei Watch, Samsung Gear Sport, Samsung Gear, and Fitbit Versa.

How Do Smartwatches Work?Android watches work by connecting to a smartphone and retrieving messages, notifications, and other app data over Wi-Fi or Bluetooth connection.

Most Android smartwatches will work with any Android phone as long as you are able to download and run the necessary smartwatch apps. Most of these watches can also work with iOS Apple iPhones.

Smartwatches have many features that may appeal to people who like to track their physical activity. They offer just about all the functionality of a fitness tracker such as Fitbit while also providing additional benefits such as text, call, and app notifications.The watch can keep track of such metrics as your step count, distance walked or ran, and burnt calories. Additional apps can monitor your sleep and heart rate.

A smartwatch is a wearable computer in the form of a watch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides 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, smartwatches released since 2015 have more general functionality closer to smartphones, including mobile apps, a mobile operating system and WiFi/Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth headset. Some models, called watch phones (or phone watches), have mobile cellular functionality such as making telephone calls.

Software may include digital maps, schedulers and personal organizers, calculators, and various kinds of watch faces. The watch may communicate with external devices such as sensors, wireless headsets, or a head-up display. Like other computers, a smartwatch may collect information from internal or external sensors and it may control, or retrieve data from, other instruments or computers. It may support wireless technologies such as Bluetooth, Wi-Fi, and GPS. For many purposes, a "watch computer" serves as a front end for a remote system such as a smartphone, communicating with the smartphone using various wireless technologies. Smartwatches are advancing, especially their design, battery capacity, and health-related applications.SpO2, workout, etc.

The first digital watch, which debuted in 1972, was the Pulsar manufactured by Hamilton Watch Company. "Pulsar" became a brand name which would later be acquired by Seiko in 1978. In 1982, a Pulsar watch (NL C01) was released which could store 24 digits, making it most likely the first watch with user-programmable memory, or "memorybank" watch.

With the introduction of personal computers in the 1980s, Seiko began to develop computers in the form of watches. The Data 2000 watch (1983) came with an external keyboard for data-entry. Data was synced from the keyboard to the watch via electro-magnetic coupling (wireless docking). The name comes from its ability to store 2000 characters.RS232C interface.Seiko Epson and was powered by a computer on a chip and was compatible with most of the popular PCs of that time, including Apple II, II+ and IIe, BBC Micro,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".

During the 1980s, Casio began to market a successful line of "computer watches", in addition to its calculator watches. Most notable was the Casio data bank series. Novelty "game watches", such as the Nelsonic game watches, were also produced by Casio and other companies.

In 1998, Steve Mann invented, designed, and built the world"s first Linux wristwatch,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 fully compatible. This watch is sometimes considered the first smartwatch as it was the first one to offer graphics display (albeit monochrome) and many 3rd party applications (mostly homebrew).

In 1999, Samsung launched the world"s first watch phone, the SPH-WP10. It had a protruding antenna, a monochrome LCD screen, and a 90-minutes of talk time with an integrated speaker and microphone.

In June 2000, IBM displayed a prototype for the WatchPad, a wristwatch that ran Linux. The original version had only 6 hours of battery life, which was later extended to 12.MB of memory and ran Linux 2.2.Citizen Watch Co. to create the "WatchPad". The WatchPad 1.5 features a 320 × 240 QVGA monochrome touch sensitive display and runs Linux 2.4.Bluetooth, 8 MB of RAM and 16 MB of flash memory.

In the same year, Microsoft announced the SPOT smartwatch and it began hitting stores in early 2004.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.

Sony Ericsson teamed up with Fossils, and released the first watch, MBW-100, that connected to Bluetooth. This watch notified the user when receiving calls and text messages. Though the watch was not popular as it would only connect and work with Sony Ericsson phones.

In 2009, Hermen van den Burg, CEO of Smartwatch and Burg Wearables, launched Burg the first standalone smartphone watch with its own SIM card and not requiring to be tethered to a smartphone. Burg received the award for the Most Innovative Product at the Canton Fair in April 2009

Pebble (watch) was an innovative smartwatch that raised the most money at the time on Kickstarter reaching $10.3 Million between 12 April – 18 May 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.Android or iOS device using both Bluetooth 2.1 and Bluetooth 4.0 (Bluetooth Low Energy) using Stonestreet One"s Bluetopia+MFi software stack.USB-cable that attaches magnetically to the watch to maintain water resistance capability.water-resistance to the list of features.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.

In 2013, the claim to first ever smartwatch to capture the full capability of a smartphone was laid by startup Omate with the TrueSmart. The TrueSmart originated from a Kickstarter campaign which raised over 1 million dollars, making it the 5th most successful Kickstarter to date. The TrueSmart made its public debut in early 2014.Wearable technology, such as Google Glass, was speculated to evolve into a business worth US$6 billion annually, and a July 2013 media report revealed that the majority of major consumer electronics manufacturers were undertaking work on a smartwatch device at the time of publication. The retail price of a smartwatch could be over US$300, plus data charges, while the minimum cost of smartphone-linked devices may be US$100.

As of July 2013, the list of companies that were engaged in smartwatch development activities consists of Acer, Apple, BlackBerry, Foxconn/Hon Hai, Google, LG, Microsoft, Qualcomm, Samsung, Sony, VESAG and Toshiba. Some notable omissions from this list include HP, HTC, Lenovo, and Nokia.Christopher Mims identified the following points in relation to the future of smartwatches:

Insufficient battery life is an ongoing problem for smartwatch developers, as the battery life of devices at the time of publication was three to four days and this is likely to be reduced if further functions are added.

The success level of smartwatches is unpredictable, as they may follow a similar trajectory to netbooks, or they may fulfill aims akin to those of Google Glass, another wearable electronic product.

Acer"s S.T. Liew stated in an interview with gadget website Pocket-Lint, "... I think every consumer company should be looking at wearable. Wearable isn’t new … it just hasn’t exploded in the way that it should. But the opportunity’s for billions of dollars" worth of industry."

As of 4 September 2013, three new smartwatches had been launched: the Samsung Galaxy Gear, Sony SmartWatch 2,Qualcomm Toq.Dallas, Texas, completed its crowd-funding process on Kickstarter for its HOT Watch smartwatch in September 2013. This device enables users to leave their handsets in their pockets, since it has a speaker for phone calls in both quiet and noisy environments.

In April 2014, the Samsung Gear 2 was released among the few smartwatches to be equipped with a digital camera. It has a resolution of two megapixels and can record video in 720p.

Smartwatches have risen in popularity during the 2010s. Today, they are often used as fitness trackers, smartphone entertainment or communication "companions".Fitbit, Amazfit, Huawei, Fossil and Garmin.

Many smartwatch smartphone models manufactured in the 2010s are completely functional as standalone products. Some are 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 provide full GPS support, displaying maps and current coordinates, recording tracks, and bookmarking locations. With Apple, Sony, Samsung, and Motorola introducing smartwatch models, 15 percent of tech consumersadvanced hypertargeting modules were introduced to the devices; companies aim to use advertisements tailored for smartwatches.

"Sport watch" functionality often includes activity tracker, or fitness tracker, features as included on GPS watches made for training, diving, and outdoor sports. Functions may include training programs (such as intervals), lap times, speed display, GPS tracking unit, route tracking, dive computer, heart rate monitor compatibility, Cadence sensor compatibility, and compatibility with sport transitions (as in triathlons). Other watches can cooperate with an app in a smartphone to carry out their functions. They are paired usually by Bluetooth with a smartphone. Some of these only work with a phone that runs the same mobile operating system; others use a unique watch OS, or otherwise are able to work with most smartphones. Paired, the watch may function as a remote to the phone. This allows the watch to display data such as calls, SMS messages, emails, calendar invitations, and any data that may be made available by relevant phone apps. Some fitness-tracker watches give users reports on the distance walked, hours slept, and so on.

From about 2015 several manufacturers released smartwatches with LTE support (watch smartphones or autonomous vs. connected watches), enabling direct connection to 3G/4G mobile networks for voice and SMS use, without the need to carry a paired smartphone.

Tests by UK consumer organisation Which? found by detailed testing that ultra-cheap smartwatches and fitness trackers sold online had serious security flaws including excessive data collection, data not stored securely, no way to opt out of data collection, and no security lock function to lock out thieves or other unauthorised users. Typically a watch app might request permission to collect and store "personally identifiable information and personal property information", such as information on passport, transactions, bank balances, and ID cards; the app is unusable if permission is denied. The user cannot know if information is being stored securely, and it cannot be deleted. There is no control over whether the supplier views it or sells it on, for whatever purpose. In many cases data collected is not encrypted when transmitted to the supplier.

Which? did not specifically test functionality of ultra-cheap watches, but while checking security they noticed that some displayed heart rate, blood oxygen measurements, and counted steps while not being worn or moved; they said that this "suggests they are at best inaccurate and at worst useless".
