Apple Watch Series 8, Apple Watch Ultra, and Apple Watch SE 2 announced

The Apple Watch Series 8 has arrived, alongside the Apple Watch Ultra and Apple Watch SE 2, at this year's September 7 ‘Far Out' Apple Event. 

First up, the Apple Watch Series 8. It's packing new features including the much-touted skin temperature sensor, which performs the dual function of improving sleep tracking and menstrual tracking simultaneously. It can detect shifts of 0.1 degree Celsius thanks to its two-sensor design.
