The Series 6 Apple Watch was unveiled at the aptly named Time Flies Apple Event, held on September 15, 2020. Apple released its dual-core S6 processor on the Series 6 watch. The tech giant claimed this latest iteration to be 20% faster than the S5 processor. Apple also improved the always-on display on the Series 6, making it brighter than on the Series 5.
The Series 6 also has a blood oxygen app that works alongside a new in-watch sensor. This new sensor is the electrocardiogram app, an app to monitor sleep, and an always-on altimeter.
