Apple released the new Apple Watch Series 8 and Apple Watch SE last week which is probably and very minor upgrade from the Apple Watch Series 7 and the original Apple Watch SE.
Some of the new features includes the new S8 chip which has minimal performance upgrades from the S7 and S6 chips, crash detection, and international roaming.
There's also a new temperature sensor on the Series 8 which helps with menustrual cycle tracking for females.
The Apple Watch Series 8 and the second generation Apple Watch SE have very minimal upgrades compared to the new Apple Watch Ultra with many new features. Our review on the Apple Watch Ultra will be available soon.
