A smart watch is a digital wristwatch equipped with advanced technology, making it significantly smarter than an ordinary wristwatch. It functions much like a smartphone, with features such as internet connectivity, GPS, Bluetooth, and the capability to run a wide range of mobile apps. Depending on the model and make, smart watches can make phone calls, send and receive messages, play music, monitor health and fitness by tracking heart rate, steps, sleep, and more. They essentially serve as a wearable computer or an extension of one’s smartphone, offering timely, personalized notifications straight on the user’s wrist.
