Apple Watch is a line of smartwatches designed, developed, and marketed by Apple Inc. It incorporates fitness tracking and health-oriented capabilities with integration with iOS and other Apple products and services.
Apple Watch relies on a wireless connection to an iPhone to perform many of its default functions such as calling and texting. However, Wi-Fi chips in all Apple Watch models allow the smartwatch to have limited connectivity features away from the phone anywhere a Wi-Fi network is available.
As of 2019, five generations and five series of Apple Watch have been released. The last two series are currently produced:
Apple Watch (2015–2016)
