Apple Watch Series 8 Aluminum – 41mm
The Apple Watch Series 8 isn’t reinventing the wheel — nor is it going to a circular design. In fact, the Series 8 looks exactly like the Series 7 that can before it. That means it’s available in both 41mm and 45mm sizes. The Apple Watch Series 8 retains its crack-resistant front crystal and its Aluminum and Stainless Steel finish options.
It is also certified IP6X dust resistant and water resistant up to 50 meters, as well as swimproof.
Apple Watch Series 8 Aluminum: Display
Series 8 features the same 41mm and 45mm display options with an edge-to-edge Always-On Retina display with up to 1000 nits of brightness.
The rumors are true; Apple has included a temperature sensor in the Apple Watch Series 8. The sensor is sensitive enough to sense a 0.1 degree Celsius temperature change in your body. Plus, the Series 8 take your wrist temperature during sleep every five seconds. A big part of the sensitivity is the two-sensor design — one sensor on the back of the watch, near the skin, and another under the display. Apple states this helps eliminate interference from the outside environment.
Thanks to two new and improved sensors: a 3-axis gyroscope and a G-Force accelerometer, the Apple Watch Series 8 will be able to tell when you are in a crash.
Apple Watch Series 8 Aluminum: Battery Life
The Apple Watch Series 8 has the same battery life as the previous model when using it like normal; however, there is a new low-power mode.
