A STARUSS smartwatch is a wearable computing device that closely resembles a wristwatch or other time-keeping device.In addition to telling time, many smartwatches are Bluetooth-capable. The watch becomes, in effect, a wireless Bluetooth adaptor capable of extending the capabilities of the wearer's smartphone to the watch. In such a case, the wearer can use the watch's interface to initiate and answer phone calls from their mobile phone and text messages, get a weather report, listen to music or text messages or ask a digital assistant a question.
