Comparison of Apple Watches in 2025: Which Smartwatch to Choose Among the New Models

On September 9, Apple held its long-awaited presentation and unveiled its new gadgets. This year, all smartwatch lines have been updated, resulting in the Apple Watch SE 3, Apple Watch Ultra 3, and Apple Watch Series 11. Their basic functionality is the same, but they have different specific options and sizes. In this article, we will compare the differences between the Apple Watch SE 3 and Apple Watch Series 11, take a look at the flagship series, and help you choose the model that is best for you. 

What do the New Apple Watches Have in Common? 

All three models run on the S10 chip and confidently handle basic tasks: they sync with your iPhone, display notifications, accept calls, support Apple Pay payments, and track your daily activity. You can use Apple Watch for sports: built-in sensors track calories burned during workouts, steps taken, and heart rate. 

What else can smartwatches do: 

• Monitor heart rate and heart rhythm 

• record low activity levels and suggest a warm-up; 

• assess sleep quality based on duration and physiological indicators. 

The Apple Watch Ultra and Apple Watch Series models can now detect signs of hypertension — the watch will warn you if it notices such a trend. The device determines your location and supports SOS signals. Among the new options is Workout Buddy, a feature that analyzes your workout using AI and encourages you. However, it is only available if you are paired with an iPhone that supports Apple Intelligence and Bluetooth headphones, and the device language is English. 

Which Apple Watch to Choose: Differences 

The new series differ in terms of hardware and battery life, specific features, case materials, and device dimensions. These characteristics determine the price of the Apple Watch in 2025. 

Flagship Apple Watch Ultra 3: Functions for Extreme Activities 

If you need an Apple Watch for travel and an active lifestyle, the third generation of the flagship series is what you need. The Apple Watch Ultra 3 is worth buying for those who spend a lot of time hiking, on expeditions, and enjoying extreme sports, including high-speed ones. The watch is suitable for diving, allowing you to dive to a depth of up to 100 m. 

For the first time in the line, there is support for satellite communication with an SOS function — a useful option for cycling trips far from civilization, climbing, or long routes. But keep in mind that it does not yet work in all regions: the service is available in the US, Canada, Australia, Japan, New Zealand, and some European countries — see the reference guide for a complete list. 

Dual-frequency GPS perfectly determines your location in difficult conditions: whether you are in the mountains, forest, or dense urban areas. 5G support has also been added. These are the best smartwatches of 2025 also because of their long battery life: they last up to 42 hours in standard mode and up to 72 hours in energy-saving mode. The screen has retained its brightness of 3000 nits and now has wide viewing angles, while remaining the leader in size at 49 mm. 

Balanced Apple Watch Series 11: an Overview 

When comparing the Apple Watch Ultra 3 and Apple Watch Series 11 for everyday use, the latter definitely wins. It is a full-fledged flagship for every day: the watch is suitable for morning runs, snorkeling, and relaxing in the mountains. The Apple Watch Series 11’s versatile slim case packs in a maximum of features. 

The main changes in the new generation are related to health, battery life, and ease of use. The watch supports 5G and LTE cellular connectivity and is available in seven colors and two case options — aluminum and titanium (sizes — 46 and 42 mm). Battery life is up to 24 hours in normal mode and up to 38 hours in energy-saving mode. And Ion-X glass is twice as scratch-resistant. 

You can use Apple Watch for fitness and health monitoring. They support personalized workouts, track key metrics, perform ECGs, and can warn you about high blood pressure. 

Basic Apple Watch SE 3: Features 

If you don’t need specific options and just want to track your activity and health metrics on your watch, you should buy the Apple Watch SE 3 — this series supports basic options. The watch tracks activity, sleep, and body temperature and is controlled by gestures. However, it does not perform ECGs or measure blood oxygen levels. 

The new generation features an Always-On display (screen size — 44 and 40 mm), fast charging, 5G support, and sleep apnea tracking. The case is now stronger, and the glass is four times more scratch-resistant. 

The Apple Watch SE 3 can also be considered as an option for children: the watch can be set up via a parent’s iPhone, supports a separate phone number, and helps monitor geolocation. The device holds a charge for up to 18 hours in normal mode and up to 32 hours in energy-saving mode. 

Which Apple Watch to Choose: Conclusion 

All the models listed will remain relevant for many years to come, so when choosing, you should first and foremost focus on your own priorities. For daily activity tracking, you can buy the Apple Watch SE 3. The Apple Watch Series 11 is considered a universal option for all tasks. And the Apple Watch Ultra 3 is ideal for anyone who takes their activity beyond the usual gym.
