Apple Watch Series 11 has officially arrived, and along with it, Apple has also unveiled the new Apple Watch Ultra 3 and Apple Watch SE 3. At Apple’s much-anticipated “Awe Dropping” event, the company introduced its latest smartwatch lineup with significant hardware and software upgrades that make these watches more powerful, more health-focused, and more future-ready than ever before.
This is Apple’s most comprehensive smartwatch update in three years, and the big question for users is simple: do these new changes make the Apple Watch Series 11 and its siblings must-have upgrades? Let’s dive into a detailed look at what Apple has brought to the table.
Apple Watch Series 11: The Center of Attention
The Apple Watch Series 11 is Apple’s mainstream flagship smartwatch for 2025. It builds on the success of the Series 10 but introduces notable health, performance, and durability features that make it stand out.
Key Features of Apple Watch Series 11:
- Hypertension Detection: A new blood-pressure notification system that alerts users when signs of high blood pressure are detected. This feature marks Apple’s biggest step yet in preventive health monitoring.
- Sleep Score: Apple has added a detailed sleep score system to track sleep quality and provide actionable suggestions for better rest.
- Improved Battery Life: The battery now lasts up to 24 hours on a single charge, compared to 18 hours in the Series 10.
- Stronger Glass: The Series 11 features glass that is twice as scratch-resistant as the previous generation.
- 5G Cellular Connectivity: With faster data speeds, the watch supports stronger connectivity for calls, music, and apps even without a phone nearby.
In hands-on testing, the Apple Watch Series 11 feels polished and premium. It carries the same sleek profile as its predecessor but with upgraded internals and meaningful health features that push it beyond being “just a smartwatch.”
Apple Watch Ultra 3: For Adventurers and Power Users
While the Series 11 focuses on mainstream users, the Apple Watch Ultra 3 is designed for explorers, athletes, and outdoor enthusiasts who need top-tier durability and functionality.
Key Features of Apple Watch Ultra 3:
- Satellite Connectivity: For the first time, Apple brings satellite access to its watches. This is crucial for hikers, campers, and adventurers who travel to remote areas without cellular coverage.
- Bigger Display: The Ultra 3 has a slightly larger screen with narrower borders, making it easier to read outdoors.
- Hypertension Detection & Sleep Score: Like the Series 11, it gets advanced health monitoring with high blood pressure notifications and detailed sleep analysis.
- Massive Battery Life: The watch offers 42 hours of regular use (up from 36) and an incredible 72 hours in low-power mode.
- Upgraded Chip: Powered by the S10 chip, the Ultra 3 delivers faster performance compared to last year’s S9 chip in the Ultra 2.
For serious adventurers, the Ultra 3 is the ultimate tool, combining rugged design with cutting-edge technology. Its satellite connectivity alone is a game-changer, especially for safety in isolated environments.
Apple Watch SE 3: Affordable Yet Powerful
Apple has not ignored its budget-conscious audience. The Apple Watch SE 3, starting at $249, brings many features previously reserved for higher-end models.
Key Features of Apple Watch SE 3:
- Always-On Display: For the first time, the SE model supports always-on mode, making it feel much closer to the flagship watches.
- New Sleep Score Tracking: Users can now monitor their sleep quality with detailed insights.
- Wrist Temperature Sensing: A feature previously seen in Series 9, now available on the SE 3.
- S10 Chip: Faster and more efficient performance compared to the older SE 2.
- Fast Charging: Charges twice as fast as its predecessor.
- Stronger Glass: The front cover is now four times more resistant to cracks.
- 5G Support: Bringing faster cellular speeds to the entry-level model.
In fact, during hands-on testing, the SE 3 felt surprisingly close to the Series 11 in terms of design and user experience. Unless you look closely at the profile and color differences, you might mistake one for the other. That’s a huge achievement for Apple at this price point.
Apple Watch Lineup 2025: Feature Comparison
Here’s a quick look at how the three models stack up:
| Feature | Apple Watch SE 3 | Apple Watch Series 11 | Apple Watch Ultra 3 |
|---|---|---|---|
| Starting Price | $249 | $399 | $799 |
| Display | Always-on (new) | Always-on | Larger, narrow borders |
| Processor | S10 chip | S10 chip | S10 chip |
| Cellular Support | 5G | 5G | 5G + Satellite |
| Battery Life | Up to 18 hours | Up to 24 hours | Up to 42 hrs / 72 low-power |
| Hypertension Detection | No | Yes | Yes |
| Sleep Score | Yes | Yes | Yes |
| Glass Strength | 4x crack resistant | 2x scratch resistant | Rugged Sapphire Crystal |
| Charging Speed | 2x faster | Fast charging | Fast charging |
Health and Safety at the Core
The most notable upgrade across the lineup is Apple’s deepened focus on health features. By introducing hypertension detection and detailed sleep scoring, Apple is taking proactive health tracking to the next level. These features go beyond simple step counts or heart rate checks—they aim to prevent long-term health risks.
The new blood pressure notification system is particularly important. Hypertension often goes unnoticed but can lead to serious health issues. With Apple Watch Series 11 and Ultra 3 now capable of alerting users about potential risks, the device becomes not just a fitness tracker, but a genuine health companion.
Connectivity Gets Smarter
Another major shift is the universal adoption of 5G connectivity. Faster speeds make Apple Watches more independent from iPhones, and for the Ultra 3, satellite connectivity makes it life-saving in areas without network coverage.
Apple has also ensured that older models like the Series 9, Series 10, and Ultra 2 will benefit from hypertension detection through the watchOS 26 update, proving that software continues to play a huge role in keeping Apple devices relevant for years.

Should You Upgrade to Apple Watch Series 11?
For users coming from older models like the Series 7, Series 8, or even the SE 2, the Apple Watch Series 11 offers a meaningful leap forward. With better health features, improved battery life, stronger build, and faster 5G connectivity, it feels like a complete package.
