Unpacking the Galaxy Watch Ultra2
Samsung's Galaxy Watch Ultra2 is a triumphant evolution of the Galaxy Watch Ultra. This premium smartwatch serves as the ultimate personal trainer, offering support in even the most extreme sports and environments—from deep-sea diving to uphill climbs.
This guide will unpack everything you need to know about the Galaxy Watch Ultra2, from its innovative features and next-generation hardware to its improved design and customisation options.
Design
The Galaxy Watch Ultra2 boasts a stylish, durable design that's ready for all kinds of adventures.
Size
At just 10.7 mm thick, the Galaxy Watch Ultra2 is more than 10% thinner than the original Galaxy Watch Ultra.
The lightweight body is only 61.5g, allowing you to stay active without feeling restricted by a bulky watch on your wrist.
DisplayThe Galaxy Watch Ultra2 is the world’s brightest watch so far, with 5000 nits of peak brightness, ready to be enjoyed from the 1.52-inch display. This means you’ll be able to effortlessly glance and check your pace on a run, no matter how bright the sunlight is.
Durability
To support you across all of life’s adventures, the Galaxy Watch Ultra2 prioritises durability. It has an IP69K rating, meeting the highest dustproof and watertight criteria at the time of release, with the K signalling protection against high-pressure jets. This means it’s completely dust-tight and can withstand high levels of water pressure.
The Galaxy Watch Ultra2 has 10 ATM water resistance, meaning it withstands pressures equivalent to a depth of 100 metres. It also meets the internationally recognised EN13319 European engineering standard for dive compliance. This certification means it’s safe to wear the watch while diving.
BandThe Galaxy Watch Ultra2's Flexible Band is 25% lighter than the Watch Ultra's. It has an air-pocket design that reduces irritation during extended wear, even if you're sweating or underwater. The band allows unrestricted wrist movement, offering you greater flexibility across everyday wear and active pursuits like rock climbing.
Access
For added convenience, you can access many Galaxy Watch Ultra2 features through the Quick Button. With a simple press, you'll be able to instantly record a lap, launch the Compass app, or even control tracking when diving underwater.
With the Raise to Talk function, you can raise your wrist and speak to receive Gemini and Bixby AI assistance: no touch necessary. Whether you're requesting a song without breaking your stride or setting a timer whilst holding a barbell, Raise to Talk lets you enhance your lifestyle with ease.
Key features
The Galaxy Watch Ultra2 offers innovative features to support you across every aspect of your overall health.
Sports
The Galaxy Watch Ultra2 stands out with its advanced sports features, tailored for a range of specialised sports.
About to dive into your next adventure? The Galaxy Watch Ultra2 can remain on your wrist and function as a professional-grade dive computer. With the Mares Dive App, you can access real-time insights whilst underwater, letting you monitor your speed, depth, and decompression levels to help you to keep yourself safe and get even more out of your dives.
If you prefer a higher altitude, the Galaxy Watch Ultra2 provides specialised Trail Run support, including uphill climb guidance, alerts for upcoming checkpoints, and reminders to stay hydrated. Real-time route navigation lets you explore the wilderness with confidence, no matter where you go.
The Galaxy Watch Ultra2's enhanced cycling support offers the capabilities of a cycling computer and a heart rate chest strap from your wrist. With a glance, you can access key metrics such as power, cadence (wheel revolutions per minute), heart rate, speed, duration, and distance. These insights can be specially tailored to wherever you ride, with the option to select whether you’re cycling indoors, outdoors, or on rough terrain.
Health
The Galaxy Watch Ultra2 is an invaluable tool for supporting your health across the board, with advanced AI-powered health support.
The Daily Cardio Load feature analyses your training load to provide the optimal recovery time for your needs, helping to reduce excessive cardiovascular strain. Whether you’re an avid cardio-lover or training for a specific event, this useful feature will ensure you don’t overdo it.
The Fitness Index provides detailed insights into your overall physical health. You’ll receive a daily fitness score based on your body composition and exercise records, along with personalised training content suggestions to help you reach your fitness goals.
Safety
Whether you’re on adventures, playing sports, or just going about your daily activities, the Galaxy Watch Ultra2's improved safety features can assist you if situations don't go as expected.
Hard Fall Detection and Emergency SOS are two innovative features that can work together to help you keep yourself safe.
If the Galaxy Watch Ultra2 detects a fall, a simple gesture lets you send an SOS to your emergency contacts with your current location and status, or contact emergency services if necessary. The Galaxy Watch Ultra2 will then automatically switch to power-saving mode to conserve your battery whilst you wait for help.
Hardware
The groundbreaking features of the Galaxy Watch Ultra2 wouldn’t be possible without the powerful hardware packed into the device.
Performance
The Galaxy Watch Ultra2 is equipped with the Qualcomm Snapdragon Wear Elite processor, marking the first time a Qualcomm processor has been used in a Galaxy Watch. The Qualcomm Snapdragon Wear Elite was also adopted for the Galaxy Watch 9, signalling a significant shift away from the longstanding use of Samsung Exynos processors in Galaxy Watches. The Snapdragon Wear Elite enables the Galaxy Watch Ultra2 to last longer, run faster, and use less power than the original Galaxy Watch Ultra. It prioritises system and workload optimisation to ensure strong performance and top speeds.
The Galaxy Watch Ultra2 has 64GB of storage, doubling the original Galaxy Watch Ultra’s 32GB storage capacity. This means more space for what you love, from dozens of apps to suit your needs to hundreds of downloaded workout playlists.

Battery
The Galaxy Watch Ultra2 features a 35% larger 800 mAh battery that delivers up to 60 hours of use. This is a huge leap from the original Ultra’s 590 mAh battery, allowing up to 20 hours of outdoor workout tracking and up to 16 hours of route workout tracking in exercise power saving mode.
The Galaxy Watch Ultra2’s improved battery means you can spend more time out in the world instead of waiting for your watch to charge. You’ll be able to enjoy longer activities, from backpacking to multi-day hikes. There's also the added peace of mind that if an emergency were to happen, the extended battery life means you can call for help if needed.
Final thoughts
The Galaxy Watch Ultra2 is more than a regular smartwatch; it’s the ultimate personal trainer, able to assist you from the depths of the sea to the steepest of mountain trails.
If you’re an outdoor activity enthusiast wanting to get even more out of your adventures, or you’re serious about your fitness and value a smartwatch with endurance that matches your own, the Galaxy Watch Ultra2 can help enhance your lifestyle.
