Smartwatches are wearable-technology devices that maintain a wireless connection to a device, usually a smartphone. The watches can alert users to text messages, incoming calls, instant messages, social network updates and more coming into device. Some smartwatch models also allow you to accept and take phone calls. Smartwatches can also run apps either through your smart phone or on the watch itself.
