A smartwatch or smart watch is a computerized wristwatch with functionality enhanced beyond timekeeping, often with features comparable to a PDA. While early models were capable of performing basic tasks like calculations, translations, or playing games, modern smartwatches are effectively wearable computers. Many smartwatches run mobile apps, some run on a mobile operating system, and a few have full mobile phone capability, while others function as mobile media players, with playback of FM radio and audio and video files, with sound via Bluetooth headset.
