The Apple Watch has changed the market of health and fitness trackers forever since its launch in 2014.
The original Apple Watch was announced on September 9, 2014, and was available for purchase on April 24, 2015.
Apple introduced the Apple Watch in three varieties - the Apple Watch, Apple Watch Sport, and Apple Watch Edition.
The Series 2 was a big deal because it added vital features to the wearable, including GPS and waterproofing, which remain key features to this day.
The Series 4 was the first Apple Watch to include ECG sensors, which allowed the wearer to take an electrocardiogram from their wrist.
The Apple Watch Series 5 was the last Apple Watch to offer the white ceramic case option, but it introduced titanium cases, a compass app, and more storage.
The Series 6 added SpO2 monitoring and basic sleep tracking along with two new colors.
The Series 7 retained the same overall design as previous models, including a big feature of a larger display size.
The Apple Watch Series 8 introduced body temperature monitoring, improved sleep-tracking functionality, and car crash detection.
Apple's budget-friendly smartwatch, the Apple Watch SE, got an upgraded S8 processor for faster performance and functionality and Fall Detection.
The Apple Watch Ultra was Apple’s first rugged smartwatch, designed for those who love outdoor and extreme activities.
