Apple Watch Series 8 has an innovative sensor that tracks your temperature while you sleep, so you can see changes over time. Cycle Tracking uses this data to provide a retrospective estimate of when you likely ovulated, which can be helpful for family planning.

The ‌Apple Watch SE‌ is a low-cost option that still offers many of the Apple Watch features that have made the device so popular over the years, while the Apple Watch Series 8 offers a more feature-rich experience with additional health monitoring capabilities.

Size and design The Apple Watch Series 8 looks the same as the Series 7, with the same thin bezels. The size also stayed the same. You can choose between 41mm and 45mm. The Series 8 aluminum is available in the 4 colors Midnight (black), Starlight (white gold), red, and silver.

There are essentially two main new additions with the Apple Watch Series 8. Firstly, there's a new temperature sensor that monitors your skin temperature. Many fitness trackers use this to identify an incoming infection, but Apple Watch Series 8 uses it to help with cycle and fertility tracking.

Overall, the Apple Watch Series 8 is a very minor upgrade over the Series 7, with the body temperature sensor and Crash Detection being the only significant changes, meaning that it is difficult to recommend upgrading.

The Verdict: which Apple Watch is right for me? As you can see, the two models presented are very similar. If you don't need the temperature sensor or accident detection, opt for the Apple Watch 7 or even the Apple Watch Series 6 for that matter. The price difference between models is sometimes substantial.

While the Series 8's extra health sensors are the biggest reason to potentially choose it over the SE, there are a few other extras to consider. The Series 8 can charge more quickly than the SE, as it inherits the fast-charging capabilities of the Series 6 and 7.
