Apple Watch Series 4

The Apple Watch is a line of smartwatches developed and marketed by Apple. It has fitness tracking, health-oriented capabilities, and wireless telecommunication, integrating with watchOS and other Apple products and services. The first Apple Watch was released in April 2015, and quickly became the world's best-selling wearable device. 4.2 million were sold in the second quarter of fiscal 2015, and more than 115 million people were estimated to use an Apple Watch as of December 2022. Apple has introduced a new generation of the Apple Watch with improved internal components each September – each labeled by Apple as a 'Series', with certain exceptions.
