A smartwatch is a mobile device with a touchscreen display, designed to be worn on the wrist
The first wristwatch to be considered a smartwatch is the Pulsar made by Hamilton Watch Company in 1972, which featured a LED digital display and a built in calculator. Later on, Seiko acquired Pulsar and came out with the RC-1000 Write Terminal in 1984 which was powered by a Seiko Epson computer chip; it was also compatible with most PCs at that time. In 1994, the Time Datalink wristwatch came out and had the ability to wirelessly transfer data to PCs. In 1998 was when Steve Mann invented and designed the first Linux wristwatch. Shortly after, IBM decided to join the market with it's own wristwatch, which also ran on Linux in 2000. This is when the smartwatch innovations started to pick up. Many companies came out with their own versions or updated their current products.
