Apple Watch Series 11 & Apple Watch SE 3 share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Apple Watch Series 11 rather than the Apple Watch SE 3.

Why Do I Recommend The Apple Watch Series 11?
- The Apple Watch Series 11 features an Always-On Retina LTPO OLED display for continuous visibility of time and widgets without raising the wrist, while the Apple Watch SE 3 uses a standard Retina display that turns off when inactive.
- Apple Watch Series 11 comes with a Blood Oxygen sensor for real-time SpO₂ tracking and better wellness insights, whereas the Apple Watch SE 3 lacks a blood oxygen monitoring system.
- It includes an ECG app to record electrical heart activity for detecting irregular rhythms, while the Apple Watch SE 3 does not support ECG readings.
- The Apple Watch Series 11 has a temperature sensor for cycle tracking and body temperature trends, whereas the Apple Watch SE 3 has no temperature monitoring feature.
- Apple Watch Series 11 supports on-device Siri processing for faster responses and offline functions, while the Apple Watch SE 3 relies on cloud-based Siri requiring internet access.
- It features a U2 Ultra Wideband chip for precise location tracking and improved Find My accuracy, while the Apple Watch SE 3 has no UWB support.
- The Apple Watch Series 11 comes with fast charging to reach 80% in under an hour for quicker turnaround, whereas the Apple Watch SE 3 charges at a standard slower rate.
- Apple Watch Series 11 includes IP6X dust resistance for better durability in sandy or dusty environments, while the Apple Watch SE 3 lacks an official dust-resistance rating.
Maybe the Apple Watch SE 3 price can make you comfortable because it’s a little bit cheaper than the Apple Watch Series 11. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.
