A smartwatch is a portable, wearable computer designed to be worn on the wrist.

While they resemble traditional wristwatches, they function as much more than simple timekeepers. Most modern models operate via a touchscreen interface. They typically rely on mobile applications that run on a connected device, such as a smartphone, to provide core functions. Some high-end models include cellular capabilities. This allows users to make and receive phone calls directly from their wrist.

The internal mechanism of a smartwatch involves a complex integration of hardware and software. Most devices are powered by a rechargeable lithium-ion battery. The visual interface usually consists of a backlit liquid-crystal display (LCD) or an organic light-emitting diode (OLED) display.

To interact with the physical world, smartwatches use various internal and environmental sensors. These include accelerometers to measure motion and gyroscopes to track orientation. Altimeters and barometers measure changes in altitude and air pressure. Many watches also include GPS receivers to determine geographic location.

Smartwatches can be categorized by their specific functional strengths. Many serve as activity trackers by incorporating body sensors. These sensors include pedometers to count steps, heart rate monitors, and electrocardiogram (ECG) sensors. Some even feature galvanic skin response sensors. Other models focus on communication or media. They may act as portable media players or FM radios. Some devices, like the Sony Ericsson MBW-100, were specifically designed to connect via Bluetooth to notify users of calls and texts.

The history of these devices began with the first digital watch, the Pulsar, introduced by the Hamilton Watch Company in 1972.

By 1982, a Pulsar model could store 24 digits, marking a likely first for user-programmable memory. In 1984, Seiko released the Data 2000, which could store 2,000 characters. This device required an external keyboard for data entry. Data was transferred to the watch using electromagnetic coupling, a form of wireless docking. During the same era, Casio marketed successful "computer watches," such as the Data Bank series.

Innovation continued through the 1990s with unique data transfer methods. The Timex Datalink, introduced in 1994, was the first watch capable of wireless data transfer from a computer.

It used an optical sensor to detect patterns of visible light displayed on a computer monitor. In 1998, Steve Mann designed the world's first Linux wristwatch. Mann was later recognized as "the father of wearable computing" at a 2000 presentation. In 1999, Samsung launched the SPH-WP10, which was the world's first watch phone. It featured a monochrome LCD and provided 90 minutes of talk time.

The 2000s saw the rise of specialized operating systems and standalone features. IBM displayed the WatchPad prototype in 2000, which ran the Linux operating system. It featured 8 MB of memory and was later upgraded with a fingerprint sensor. In 2004, Microsoft released the SPOT smartwatch. SPOT stands for Smart Personal Objects Technology. This device used FM waves to transmit news, weather, and stock prices.

In 2009, Hermen van den Burg launched Burg, the first smartphone watch to include its own SIM card. This allowed the device to be "standalone," meaning it did not require a tethered smartphone.

Recent years have focused on connectivity and massive consumer interest. The Pebble smartwatch, funded via Kickstarter in 2012, raised $10.3 million. It featured a transflective LCD and a battery life reported at seven days. The device was also water-resistant up to 5 atm, allowing for swimming or diving. By 2013, analysts suggested it might be the "year of the smartwatch" because components had become small and affordable. However, developers still face challenges, such as insufficient battery life. As of 2013, many major companies, including Apple, Google, and Samsung, were actively developing wearable technology.
