**Design and Materials**

The Apple Watch series 8 and the Apple Watch series 7 have very similar designs, essentially looking identical between the two of them. However, there are a few small differences worth noting. One of the notable differences is the return of Silver as an option for the Apple Watch series 8, which was not available in the Apple Watch series 7. The other difference lies in the materials used to make the cases. In the Apple Watch series 7, users could choose from aluminum, stainless steel, or titanium. In contrast, the Apple Watch series 8 is only available in two materials: stainless steel and aluminum. Unfortunately, titanium is no longer an option for the Apple Watch series 8, and those looking for a more premium option may want to consider the Apple Watch Ultra instead.

The Apple Watch series 8 is available in both 41 and 45 millimeter sizes, just like its predecessor. The internal design of the watch has also undergone some changes. Apple has moved to the new S8 SIP system, which houses several components necessary for the Apple Watch to operate. These include the ultra-wideband chip, wireless components, and the CPU. However, it's worth noting that the CPU on the Apple Watch series 7 and the Apple Watch series 8 is the same, so there isn't a significant difference in terms of speed and performance.

**Sensor Upgrades**

One of the notable upgrades in the Apple Watch series 8 is the inclusion of new sensors. These include two updated gyroscopes, which are used for crash detection. The gyroscope accelerometer detects an impact or shift in orientation, while the barometer detects a sudden pressure change. Additionally, there's a rear-facing sensor on the back of the watch that faces the wrist, and an outward-facing sensor that faces the ambient room. These sensors work together to monitor basal body temperature when wearing the Apple Watch series 8 for sleep tracking.

The new temperature sensors in the Apple Watch series 8 can detect changes in basal body temperature over time, allowing the watch to identify potential issues such as excessive alcohol consumption or illness. However, it's worth noting that you cannot get an immediate reading of your body temperature on demand using the Apple Watch series 8. Instead, the watch will provide retroactive readings based on the data collected from the sensors.

**Other Features**

The Apple Watch series 7 and the Apple Watch series 8 share many similarities in terms of features. Both watches have the same watch faces, CPU speeds, battery life, and resistance to dust and water. They also support the same features such as Backtrack and Low Power Mode to extend battery life up to 36 hours.

One notable feature that is exclusive to the Apple Watch series 8 is the integration of two new sensors for cycle tracking. The watch can detect when you may have ovulated based on your basal body temperature readings, providing a more accurate picture of your menstrual cycle.

**Conclusion**

Ultimately, whether or not it's worth upgrading from the Apple Watch series 7 to the Apple Watch series 8 depends on individual needs and preferences. While the new features such as crash detection and basal body temperature tracking are significant upgrades, they may not be necessary for everyone. Additionally, the Apple Watch series 7 is still a great watch that offers many of the same features and functionality as its successor.

That being said, those who have been holding out for an upgrade from their older version of the Apple Watch may find the new features in the Apple Watch series 8 to be enticing enough to make the switch. Additionally, users who want the latest and greatest technology without breaking the bank may also consider upgrading to the Apple Watch series 8.

Ultimately, it's worth noting that many of the new features in the Apple Watch series 8 are coming in watchOS 9, which is available on previous versions of the Apple Watch as well. This means that those who don't need the latest and greatest technology may still be able to access these features without having to upgrade their watch.
