A smartwatch is a wearable device that combines traditional timekeeping functions with advanced features such as fitness tracking, mobile payments, and notifications from your phone. It typically connects to your smartphone via Bluetooth and can provide alerts for calls, texts, emails, and other apps. Some models also offer voice commands, GPS tracking, heart rate monitoring, and even the ability to make phone calls independently of a connected device. Smartwatches are often designed to be fashionable as well as functional, with a variety of styles and colors available.
