The document summarizes the history and features of smartwatches. It notes that the idea originated from Dick Tracy's communicating watch in comics in the 1940s. Early smartwatches were introduced in 2004 but discontinued by 2008. Modern smartwatches allow users to access news, weather, sports and messages from their wrist and receive phone calls and text messages without their phone. They also track health and fitness metrics like calories burned and heart rate. While useful, smartwatches must be synced with a user's cell phone to function.
