Why is the Apple Watch SE 3 so much cheaper than the rest of the lineup?
The Apple Watch SE 3, launched in September 2025, costs $150 less than the Series 11 by sacrificing features like ECG, blood oxygen monitoring, and longer battery life.
The Apple Watch SE 3 was released in September 2025 alongside the Series 11 and Ultra 3. It is $150 cheaper than the Series 11, with the price difference explained by several trade-offs.
Design differences
The SE 3 comes in 44mm and 40mm sizes, while the Series 11 offers 46mm and 42mm. The Series 11 has a brighter and more durable display, useful for outdoor use. The SE 3 uses a recycled aluminum case, whereas the Series 11 is available in titanium.
Missing features
The SE 3 lacks ECG and blood oxygen apps, as well as a depth gauge and water temperature sensor. There is no Precision Finding for iPhone. However, it still tracks heart rate, including resting and workout zones.
Battery life and charging
The Series 11 boasts up to 24 hours of battery life (38 hours in low power mode), compared to the SE 3's 18 hours (32 hours in low power). Charging is also slower.
Who should buy the SE 3?
The SE 3 is the best budget Apple Watch available. It's ideal for first-time users, students, and seniors. It includes the same usability and tracking features as other models, such as advanced sleep tracking with sleep apnea notifications, wrist temperature sensing, Workout Buddy, vitals, and watchOS 27. However, regular Apple Watch users might prefer an older Series model or save up for the Series 11.
