A smartwatch is a wearable digital device that we wear on our wrists like the traditional analog watch. Being a computing device, the smartwatch offers applications that let us track fitness, emails, calls, messages, and more.

Notable details
Smartwatch has hardware and an operating system. It is like a very small computer on our wrist.
It is waterproof and can last 5 feet underwater for around 30 minutes. We can comfortably wash our hands, without worrying about getting the smartwatch affected.
The UI (display) consumes most of the battery. Smartwatch has a small UI, which makes the battery last for a long time.
Because of its small UI unlike smartphones and computers, the usage of smartwatches is mostly limited to some functions.
