Apple Watch SE (1st Gen) vs Apple Watch Series 10
The Verdict
Apple's budget-friendly SE (1st Gen) delivers core smartwatch functionality at an attractive price point, featuring heart rate monitoring, sleep tracking, and GPS with up to 18 hours of battery life. However, the Series 10 ($399) represents a significant step forward in health capabilities, adding ECG, blood oxygen, and skin temperature sensors that serious fitness enthusiasts will appreciate. Display technology differs notably,the SE uses standard LTPO OLED without always-on, while Series 10 boasts a brighter 2000-nit LTPO3 display with permanent always-on capability. Performance advantages favor Series 10's newer S10 chip and watchOS 11 versus the SE's dated S5 processor running older software. Battery life matches at 18 hours, though Series 10 adds a useful 36-hour Low Power Mode. For basic fitness tracking and notifications, the SE remains excellent value. For comprehensive health monitoring and modern features, Series 10 justifies its $120 premium.
