Apple Watch SE (1st Gen) vs Apple Watch Series 8
The Verdict
Apple's Series 8 justifies its $120 premium through meaningful health upgrades, delivering ECG, blood oxygen, and skin temperature monitoring absent from the SE. Display quality improves with always-on capability and higher resolution (352x430 vs 324x394), while the S8 processor offers better performance for apps and workouts. Battery longevity remains 18 hours standard, though Series 8 adds a useful 36-hour Low Power Mode. Connectivity benefits from USB-C fast charging and Bluetooth 5.3. Health-conscious users and those wanting advanced fitness tracking should invest in Series 8, while casual fitness enthusiasts comfortable with basic heart rate and sleep monitoring will find SE's value proposition compelling. For most users prioritizing comprehensive health data and future-proofing, Series 8 represents the smarter choice despite higher cost.
