Samsung Galaxy Watch Ultra 2, Apple Watch Ultra 2, and Google Pixel Watch 3 are three powerful smartwatches designed for different types of users. Here’s a simple comparison of their design, display, performance, battery, fitness features, software, and overall experience.
The smartwatch market has become much more interesting in recent years. Samsung, Apple, and Google are all trying to build watches that can do much more than show notifications.
The latest Samsung Galaxy Watch Ultra 2 brings a rugged titanium design, a huge battery, a bright AMOLED display, and Wear OS 7. Apple's Watch Ultra 2 continues to focus heavily on outdoor activities, fitness, and deep iPhone integration. Meanwhile, Google's Pixel Watch 3 takes a different approach with a cleaner design and strong health-tracking features.
So, which one deserves a place on your wrist? Let's compare them. 👇
The Galaxy Watch Ultra 2 has the most rugged appearance of the three. It comes with a 47mm titanium body, Sapphire crystal protection, IP69K protection, and 10ATM water resistance. It is designed to handle outdoor activities while still looking premium.
The Apple Watch Ultra 2 also follows the rugged smartwatch approach. It features a 49mm titanium case and a flat Sapphire crystal display. Apple designed the Ultra series with hiking, diving, running, and other outdoor activities in mind.
The Google Pixel Watch 3 is much more understated. It comes in 41mm and 45mm sizes with an aluminium body and a rounded display. At 37 grams without the band, the 45mm version is also considerably lighter than the large rugged-style watches.
Design winner: It depends on your taste. Galaxy Watch Ultra 2 and Apple Watch Ultra 2 are better for rugged use, while Pixel Watch 3 is more comfortable for everyday wear.
The Galaxy Watch Ultra 2 features a 1.52-inch AMOLED display with up to 5,000 nits peak brightness.
That extremely high brightness is especially useful outdoors. If you frequently use your watch under direct sunlight, this can make a noticeable difference.
Apple's Watch Ultra 2 has a 49mm LTPO2 OLED Retina display with up to 2,000 nits of brightness.
The Pixel Watch 3 uses an AMOLED LTPO display with up to 2,000 nits of peak brightness and supports an always-on display.
Display winner: Galaxy Watch Ultra 2, especially for outdoor visibility.
Samsung's Galaxy Watch Ultra 2 runs Wear OS 7 with One UI 9 Watch and uses the Snapdragon Wear Elite 3nm processor. It also has 2GB RAM and 64GB storage, along with on-device AI features.
Apple's Watch Ultra 2 runs Apple's watchOS and uses Apple's smartwatch ecosystem. Its biggest advantage is how closely the watch works with an iPhone.
Google's Pixel Watch 3 uses Wear OS 5 and is powered by the Snapdragon W5 Gen 1 with a Cortex-M33 co-processor. It includes 2GB RAM and 32GB storage.
This is where your smartphone matters most.
If you use a Samsung or Android phone, the Galaxy Watch Ultra 2 makes the most sense. Pixel Watch 3 is also designed for Android users. If you're an iPhone user, Apple's ecosystem remains the obvious choice.
Software winner: Apple for iPhone users; Samsung and Google for Android users.
Battery life is one of the biggest differences between these watches.
The Galaxy Watch Ultra 2 has an 800mAh battery and is rated for around 60 hours of usage. Its larger battery is particularly useful for people who spend long hours outdoors or track lengthy workouts.
The Apple Watch Ultra 2 is rated for up to 36 hours of normal use.
The Pixel Watch 3 is rated for up to 24 hours with the always-on display, or up to 36 hours with Battery Saver mode. The 45mm version has a 420mAh battery.
Battery winner: Galaxy Watch Ultra 2, quite comfortably.
All three watches offer serious health and fitness tracking, but their strengths are slightly different.
The Galaxy Watch Ultra 2 is designed for people who want a combination of everyday health tracking and outdoor fitness. Its rugged construction and larger battery make it particularly interesting for hikers, runners, and adventure enthusiasts.
Apple's Watch Ultra 2 is also heavily focused on fitness and outdoor activities. Its larger case, diving capabilities, GPS features, and workout ecosystem make it a strong choice for athletes and outdoor users.
Google's Pixel Watch 3 takes a more everyday health-focused approach. It includes sensors for heart-rate tracking, ECG-compatible measurements, blood oxygen monitoring, skin temperature, body-response tracking, and other health features.
Fitness winner: There's no single winner. Apple is excellent for iPhone users and serious fitness tracking, Samsung offers a strong Android/outdoor combination, while Google provides a clean health-focused experience.
Storage can matter more than people expect.
The Galaxy Watch Ultra 2 offers 64GB, giving it twice the storage of the Pixel Watch 3's 32GB. Both Samsung and Google watches offer access to the Wear OS app ecosystem.
Apple's Watch Ultra 2 comes with 32GB storage.
For most people, 32GB is already enough. However, Samsung's 64GB gives users more breathing room for apps and supported content.
There isn't one perfect smartwatch for everyone.
Choose the Galaxy Watch Ultra 2 if you want a rugged Android smartwatch, a very bright display, long battery life, large storage, and on-device AI features.
Choose the Apple Watch Ultra 2 if you use an iPhone and want a premium outdoor smartwatch that works deeply with Apple's ecosystem.
Choose the Pixel Watch 3 if you prefer a smaller, lighter design and want a clean Wear OS experience with strong health and fitness features.
The Galaxy Watch Ultra 2 stands out for battery life, brightness, ruggedness, and storage. The Apple Watch Ultra 2 remains a strong choice for people already invested in Apple's ecosystem, especially outdoor and fitness users. The Pixel Watch 3 is the more compact and understated option for Android users.
In the end, your smartphone ecosystem may matter more than the specifications on paper.
And one more thing: despite the title often being searched as “Galaxy Watch Ultra 3,” Samsung's current 2026 model is the Galaxy Watch Ultra 2. So if you're shopping today, that's the Samsung model you should compare against the Apple Watch Ultra 2 and Pixel Watch 3.
