Who Is This Model Perfect For?

• Active Users Who Want to Leave Their iPhone Behind: The GPS + Cellular functionality is the main selling point. It allows you to make calls, send messages, stream music, and use data apps even when your iPhone is not nearby (requires a separate cellular plan with your carrier).

• Runners & Cyclists: Perfect for outdoor workouts where carrying a phone is inconvenient, but staying connected for safety or music is important.

• Those Focused on Women’s Health: The temperature sensing for advanced cycle tracking was a key innovation of the Series 8.

• Anyone Wanting a Premium, Feature-Rich Watch (at a potential discount): As a previous-generation model, it may be available for a lower price than a Series 9 while still offering most of the core health and connectivity features.

Important Considerations

1. Previous Generation: This is not the latest model. It lacks the Double Tap gesture and the faster on-device Siri found on the Series 9.

2. Requires an iPhone and a Cellular Plan: You need an iPhone 8 or later with a compatible version of iOS to set it up. To use the cellular features, you must also activate it with a supported plan from your wireless carrier (usually a monthly fee).

3. Bands are Interchangeable: You can easily swap the band with any other Apple Watch band of the same size (41mm/45mm for Series 8) for style or function.

Comparison to Other Models

• vs. Apple Watch Series 9: The Series 9 has a brighter display (2000 nits), the new Double Tap gesture, on-device Siri for faster and more private requests, and Precision Finding for iPhone 15 models. The core health sensors (ECG, SpO2, Temperature) are otherwise identical.

• vs. Apple Watch SE (2nd Gen): The Series 8 is superior with its Always-On Display, ECG & Blood Oxygen apps, temperature sensing, and crash detection.

Final Verdict

The Apple Watch Series 8 (41mm, GPS + Cellular, Red) is a powerful and independent smartwatch that remains highly capable.

Its standout features are the cellular connectivity for ultimate freedom from your iPhone and the temperature sensor for advanced health insights. If you find this model available and the lack of the Series 9’s newest features is not a deal-breaker, it represents an excellent value for a full-featured Apple Watch.
