Apple Watch Series vs Ultra 3
The Ultra 3 actually feels like a small computer on your wrist because it is made from titanium, with extra-long battery life and dual frequency GPS that can guide you through mountains or deep sea dives.
The Series 11 makes things simpler and even smoother. It’s best for daily use, comes in fun colors, and still tracks everything from heart rate to oxygen levels.
So, in short,Ultra 3 is about endurance; while Series 11 is about everyday balance.
Apple Watch Series vs SE 3
The SE 3 actually keeps all the core features like notifications, fitness tracking, fall detection and so on, but it skips some high end sensors like ECG and SpO₂.
If what you want is an affordable and a reliable smartwatch, then the SE 3 will cover all the basics beautifully.
But if you care so much about deeper health insights or a brighter screen, then the Series 11 is worth the extra cost.
