Detailed Feature Comparisons
Design and Construction
The Apple Watch SE features a modern design with a larger screen, thinner bezels, and more size options (40mm and 44mm) compared to the smaller 38mm and 42mm case sizes on the Series 3. Both models use aluminum cases, but the SE feels more premium with a sleeker finish and edge-to-edge glass look. The SE’s case design is also more compatible with recent watch bands.
Display Quality
Both watches use Retina OLED displays, but the SE’s is larger, brighter, and offers better visibility in sunlight. The screen area is noticeably more expansive, especially useful for text notifications and apps. While neither model has an always-on display, the SE display is crisper and more responsive to wrist movement.
Performance and Speed
The SE is powered by the S5 chip, which is significantly faster than the S3 chip found in the Series 3. This leads to quicker app launches, smoother animations, and better overall responsiveness. The difference is noticeable when opening apps or switching watch faces.
Software and Updates
The SE supports the latest versions of watchOS (including watchOS 10), ensuring access to new features and app compatibility. The Series 3 has been dropped from Apple’s support list, meaning it won’t receive future software updates, which affects security and app availability.
Health and Safety Features
The Apple Watch SE includes modern safety tools like Fall Detection, Emergency SOS, and Noise Monitoring. These features are not available on the Series 3. While both watches include standard activity tracking and heart rate monitoring, the SE goes further in delivering proactive health alerts.
Sensors and Tracking
The SE includes more advanced sensors such as an always-on altimeter and built-in compass. These make it better for outdoor tracking and navigation compared to the basic altimeter in the Series 3. Runners and hikers will find the SE far more useful in real-world conditions.
Battery and Charging
Both watches offer similar battery life—up to 18 hours with typical use. However, the SE tends to deliver slightly better power efficiency thanks to its newer chipset. Charging speeds are nearly the same since neither model supports fast charging.
Connectivity and Compatibility
The SE uses Bluetooth 5.0, which offers a more stable and power-efficient connection compared to the older Bluetooth 4.2 in the Series 3. The SE also comes with GPS + Cellular variants, giving users more flexibility if they want to use the watch without their iPhone.
