What's the difference between the Galaxy Watch8, Watch7, Watch6 and Watch Ultra?

Yes, all models provide access to notifications, apps, and everyday smart features directly from the wrist when used with a Samsung Smartphone. 

Many features work best within the Galaxy ecosystem, but core smartwatch functions like fitness tracking, notifications, and apps can still be used with compatible Android devices.

Galaxy Watch Ultra2 is built for the even more extreme, offering a hefty 800 mAh (typical) battery, the biggest yet. This means it can go for longer between charges and gather deep insights across an entire adventure weekend. A tougher titanium-cut case is able to handle atmospheric pressure to depths of 100m, while updated Google Gemini offers a natural raise-to-talk gesture. 

Galaxy Watch9 has even more on board to ensure 24/7 easy monitoring. It features a 20% larger battery than the previous model and a range of smart sensors capable of tracking workouts, reporting sleep quality and monitoring your heart health. A new Snapdragon® processor boosts battery longevity and delegates power to certain apps, so you can squeeze in an extra 10K, or grab another night of expertly monitored sleep.
