The watch can be controlled via an app. You can make calls if the watch is connected to the phone. It has a built-in speaker and microphone. It also shows notifications when connected to the phone. You can measure heart rate and blood oxygen levels. It has a calendar and calculator. The color on the side of the watch has faded slightly, otherwise, there are no issues.
