A smartwatch is a wearable device designed to be worn on the wrist that combines timekeeping with advanced digital features to support daily life and fitness. It connects to a smartphone to deliver notifications, calls, messages, and app alerts while also offering health and activity tracking such as heart rate monitoring, step counting, sleep analysis, and workout modes. With a touch display, customizable watch faces, and rechargeable battery, a smartwatch blends style, convenience, and smart functionality into a compact, everyday accessory.
