Galaxy Watch Ultra2

By comparison, the Galaxy Watch Ultra2 is built for adventurers, athletes, and anyone who needs a smartwatch that can keep up no matter where the day takes them. Its titanium frame is made to take a beating, and it's rated to handle everything from a sweaty trail run to a swim in the sea, even a dive¹.
With 64GB of storage, the Watch Ultra2 lets you carry more music, apps, and workouts directly on your wrist, so you can leave your phone behind during training or outdoor activities. It's faster and smoother to use thanks to a new chip, and its screen is the brightest yet on a Galaxy Watch, so you can still read it clearly under direct sun². The battery goes the distance too, lasting up to 60 hours on a charge, and when you do need to top up, a quick 30 minutes gets you back to 40%³.

Just raise your wrist and ask Google Gemini⁴ for help, whether that's checking the weather or getting quick answers on the go. Out on the trail, built-in GPS and route tools like Climb Guidance and a Compass watch face take the guesswork out of navigation. And once you're back, Fitness Index⁵ gives you a clear read on how fit you're getting, Daily Cardio Load⁶ tells you when to push and when to rest and Running Coach⁷ helps you build up to your next goal, one guided session at a time. The Galaxy Watch Ultra2 comes in Titanium Silver and Titanium Gray, so you can combine performance with personal style.

What are the different series of Samsung smartwatches?

Samsung has released several series of innovative smartwatches over the years and each comes with unique features. Some models are more focused on fitness tracking, while others are designed for a more traditional watch look and feel. We explore each in more detail below.

Watch5 Pro

The Galaxy Watch5 Pro debuted in 2022 and remains a standalone model in Samsung's smartwatch lineup, boasting sophisticated features including 4G connectivity and active GPS that has been optimised for outdoor adventurers.
The Galaxy Watch5 Pro features a tough Sapphire Crystal display and a titanium frame, measuring in at 45mm, the largest case size Samsung has offered on a Galaxy Watch.

One of the standout features of the Galaxy Watch5 Pro is its advanced health and fitness tracking capabilities. It includes a workout feature which lets you import GPX workout routes from your smartphone straight to your watch, while syncing your route list¹ across devices. When it's time to return, the Track Back feature keeps you on the right path thanks to voice and vibration navigation. Plus, with fall detection technology², it can send alerts to emergency contacts if you take a tumble while you're out cycling or hiking.

The Galaxy Watch5 Pro has a battery capacity³ of 590mAh. It also supports fast charging, allowing you to charge up quickly when you're on the go. It's water-resistant up to 50 metres⁴, making it the perfect companion for swimming and water sports.

It cannot detect all falls. The more physically active you are, the more likely you are to trigger Fall Detection due to high impact activity that can appear to be a fall.
3. The typical capacity has been tested under third party laboratory conditions. The typical capacity is the estimated average capacity considering the deviation in battery capacity among the battery samples tested under the IEC 61960-3 standard. Rated capacity is 573mAh. Actual battery life may vary depending on network environment, usage patterns and other factors.
4. Water resistance rating of 50 metres under the ISO standard 22810:2010. It is not suitable for diving or high-pressure water activities. If the device or your hands are wet, they must be dried thoroughly prior to handling.
