Design and Build
The Galaxy Watch Ultra 2 retains the circular dial. It weighs 61.5 grams, almost similar to the predecessor, even with a larger battery. It has a Titanium Grade 4 frame that looks and feels premium, and the matte finish doesn’t attract fingerprints. It is also 12% thinner at 10.7mm.
The smartwatch has 10 ATM+ and IP69K, so you can even wear when swimming, and it also has MIL-STD-810H and EN13319 certification, making it durable and you can now use it for diving with automatic tracking of depth, duration, and water temperature.
Additional diving features, including ascent/descent speed tracking and safe dive limits, will be available later this year through the Ultra2 Diving app developed with diving equipment manufacturer Mares, said the company.
On the back, there are heart rate sensors with glowing green LED lights when you are using them to measure heart rate, and the SpO2 sensor has glowing red lights when you start measuring. Since it has wireless charging, you don’t see any contact points.
The smartwatch has Samsung BioActive Sensor (Optical Bio-signal Sensor + Electrical Heart Signal + Bioelectrical Impedance Analysis), Temperature Sensor, Accelerometer, Barometer, Gyro Sensor, Geomagnetic Sensor, and Light Sensor.
It uses Bluetooth 6.0 to connect to Android devices and doesn’t work with iOS. There is LTE, 2.4+5GHz, NFC, L1+L5 Dual-Frequency GPS.
Coming to the strap, it is made of skin-friendly material that is designed for water swimming, and its titanium buckle is light and durable. There is a wide ripple design for easy water drainage and quick sweat drying. It uses a dynamic lug system, so it can be easily attached and swapped to suit different outdoor activities.
The band is now lighter, thinner, and more breathable with a new air pocket structure. In addition to the titanium silver color that we have, the smartwatch also comes in the titanium grey color with a matching grey color band.
In addition to the Home and Back buttons, there is a Quick button, a customizable button designed for exercise, outdoor activities, and precise input. Enhanced tactile separation and an orange accent of the quick button make each button distinct, letting you navigate the watch quickly, even with gloves on.
It also allows easy access to an 86-decibel emergency siren that can be heard up to 180 metres away by holding the button for five seconds. You can set the Quick button to perform various actions by configuring the options. This also has automatic Fall Detection or hard-fall emergency SOS calling, which is standard on the Ultra series.
You find the microphones near the button, and the speaker is present on the other side. Furthermore, you can take calls directly from the watch when you connect it to the smartphone over Bluetooth. Since this has LTE, it also works as a standalone device to make and receive calls, but you have to enable the eSIM feature.
The watch is powered by Qualcomm Snapdragon Wear Elite Platform Qualcomm SDW6100 (Penta-Core, 3nm) SoC, a change from the usual Exynos chip. This has up to 2.1 GHz, 1 x high-performance Cortex-A78 core and four efficient Cortex-A55 cores. It is said to offer 54% higher single-core and 56% higher multi-core performance than the Exynos W1000 it replaces. There is 2GB of RAM, which is enough to run several apps in the background without any issues.
Display and features
Coming to the display, the Galaxy Watch Ultra2 has a large 1.52-inch (498×498 pixels) Super AMOLED colour touch screen display with up to 5000 nits peak brightness, up from 3000 nits in the predecessor. You can set it to turn on when you lift your hand, and the screen turns off in a few seconds to save power.
It doesn’t attract fingerprints, but when the screen is off, it is reflective. The company says that it has Sapphire Crystal protection. I didn’t notice any scratches during my use. The touch screen is smooth to use, has good viewing angles, and the outdoor visibility is good as well. You can adjust the brightness from Settings → Display → Brightness or directly swipe down to access the brightness settings. You can adjust it from level 1 till level 6, but the ambient light sensor is helpful in setting up the brightness according to the condition.
It still doesn’t feature a physical bezel, so you can’t rotate it. However, with the digital bezel, you need to lightly press and drag your finger clockwise or counterclockwise using the bezel on the edge of the screen to move through a list.
There is also an easy notification shade option when you swipe from the top. This has Sleep Mode, Power, Settings, Power Saving, Always on Display, Sound/Vibration, Flashlight, Brightness toggle, DND, Wi-Fi, Find My Phone, Water Lock Mode that lets you shake the watch to remove any water from the pressure sensor that is present on the back, Airplane mode, Bluetooth Headset Connection, Volume, GPS, NFC, and Theater Mode. You can manually add the network toggle, touch sensitivity, and Bluetooth toggle from the add button.
Software
The Galaxy Watch Ultra2 runs Wear OS 7 Powered by Samsung One UI 9 Watch. This brings a refreshed interface, deeper AI integration, and advanced health telemetry based on Wear OS 7.
- Raise to Talk: Activate Google Assistant or Gemini instantly by raising your wrist to your face.
- Updated Gestures: Combine double pinch for positive actions (answering calls, music control) and shake for negative actions (declining calls, dismissing alarms).
- Knock-Knock Gesture: Make a fist and bend your wrist down to trigger quick shortcuts.
- Tap to Wake: Tap the screen directly to wake up the watch display (can be toggled off in settings)
You can customize these using the Galaxy Wearable that needs to be downloaded from Google Play. The app also lets you customize watch faces. There are few built-in watch faces and several downloadable watch faces, and you can also get more watch faces using third-party apps from Google Play. The Ultra series features an automatic or manual red-monochrome Night Mode for watch faces, designed to preserve night vision during low-light outdoor use or astronomy tracking.
The app also allows you to manage the app screen, tiles, quick panel, and notifications; customize the action button, home button, and back button, including gestures. You can also install apps directly from Google Play in the Galaxy Watch. There is offline music playback support for Spotify, YouTube Music, and more to make use of 64GB internal storage.
Fitness tracking
The Samsung Health app needs to be downloaded to get more details about your activities, fitness, food and sleep tracking. The Watch Ultra2 has several sports modes, including a new Multi-Sports mode that can be launched from Multi-Sports tiles that allow you to customize workout combinations and measure the results of different workouts, including duathlons and triathlons.
Steps tracking is accurate compared to data from a phone. GPS tracking takes only a few seconds to lock for outdoor workouts and is accurate. GPS tracking doesn’t cut out if there are some intrusions like trees or bridges.
For running, it shows a lot of data, such as pace, elevation, heart rate, VO2 max, advanced running metrics, and lots more. There is a new Trail Run mode that tracks elevation, climbing progress, and terrain impact. It has dedicated outdoor GPX features—like importing GPX route files, turn-by-turn navigation for trails, and the reverse Track Back feature—reinforces its rugged outdoor credentials against dedicated Garmin/Suunto watches.
The new Nutrition Alert feature expands the existing Sweat Loss feature by estimating sweat loss based on body weight and providing hydration guidance during runs. The Functional Threshold Power (FTP) for cycling, accurately measures maximum cycling power in just 4 minutes with AI-powered FTP metrics.
You can press the action button to pause a workout in the middle and resume it or stop it. You can also compare these with recent runs. Samsung still doesn’t show running power that is available even in mid-range Amazfit smartwatches, other than Garmin, Suunto, Polar, and other high-end smartwatches. Considering the premium price.
The Energy Score feature uses Galaxy AI that analyzes key indicators of your overall condition and gives you a daily score based on your recent activity, sleep patterns and overnight heart signals. There are fitness coaching videos in the app. Together feature lets you track the daily step count of your friends.
You can share the workout data as an image, and there is Strava support and Technogram sync, which can be enabled from Settings and Selecting Services. There is also Health Connect sync.
Fitness Index and Body Composition
Fitness Index combines data from your daily activity, workout intensity, and built-in health sensors to give you a single score that reflects your overall physical ability. You can use it to track your progress over time and get suggestions on the right content to help you improve.
This uses body composition data. For this you need to place the the middle and ring fingers on the home and back buttons and keep them still during measurement. This takes a few seconds to measure, and you need to enter the weight manually. Just like the digital weighing scales, this has sensors in the home and back buttons to send electrical signals into the body and receive it back to get back details such as body fat, skeletal muscle, body water, BMI, and BMR. You can’t say this is 100% accurate, since there are slight changes between the data from this and the Mi Body Composition Scale.
Sleep tracking
Sleep tracking is accurate, and there is also data for different stages such as REM, light, and deep with a chart. It also shows when the blood oxygen went below 90%, skin temperature during sleep, and respiratory rate. It also says the watch can detect snoring when you place the phone near your face during sleep with a microphone, but I didn’t try it.
The Sleep Coaching features are a personalized program that helps you build better sleep habits over time. This works when you wear the Galaxy Watch Ultra2 for a week to uncover your sleep type, represented as one of eight animals. Then, follow a 3- to 4-week program of simple, incremental changes designed to improve your sleep quality night after night. Overall, the watch has excellent fitness tracking and sleep tracking.
Heart rate, SpO2, and Stress monitoring
The smartwatch uses LED lights and photo-diodes to illuminate the blood vessel for a while and monitors the heart rate via the change of green light absorbed. It stores the data with date and time. There is also resting heart rate data. Compared to pulse oximeter, this is accurate. It can also measure blood oxygen and stress 24 x 7.
BP and ECG monitoring
You can also receive real-time readings and alerts for abnormally high or low heart rates with heart rate monitoring, detect irregular heart rhythms suggestive of atrial fibrillation (AFib) with IHRN (Irregular Heart Rhythm Notification), and get a deeper understanding of your heart health with electrocardiogram (ECG) and blood pressure (BP) monitoring.
However, for BP tracking, you need an upper-arm, cuff-based blood pressure monitor for calibration, and you need to do it once every 28 days for accurate results. The BP and ECG monitoring works only with Samsung phones.
Battery life
The Galaxy Watch Ultra has a huge 800mAh battery, 35% larger than the previous Galaxy Watch Ultra, and the company promises 60 hours or close to 2 and a half days of battery life with typical use with AOD off. With heart rate and stress monitoring always enabled and SpO2 monitoring during sleep, I consistently got over 3 days of battery life, which is good.
The smartwatch uses WPC-based wireless charging that requires you to use the bundled charger and doesn’t work with third-party wireless charging pads. But it also didn’t work with older Galaxy Watch chargers. Older Galaxy Watches could be reverse wireless-charged off the back of Galaxy flagship phones. Due to the redesigned rear BioActive sensor glass curvature and coil spacing, Wireless PowerShare from phones was dropped on the Ultra line.
This is the company’s first-ever Galaxy Watch with fast charging that can charge up to 40% in around 30 minutes. A full charge takes about one and a half hours, which is good. This charges one hour faster than the Galaxy Watch Ultra.
Conclusion
The Samsung Galaxy Watch Ultra2 is a well-rounded and substantial step forward over its predecessor, solidifying its place as the definitive rugged smartwatch for Android users. Samsung has addressed key areas that matter most in daily use: the move to the 3nm Snapdragon Wear Elite platform delivers noticeably snappier navigation, the 5,000-nit panel ensures unmatched outdoor visibility, and the slimmer 10.7mm titanium chassis makes it significantly more wearable despite packing a massive 800mAh battery. The multi-day endurance and faster charging curve alone resolve some of the biggest pain points of typical Wear OS devices.
Add in EN13319 diving readiness, dual-frequency GPS accuracy, and expanded health tracking, and it easily competes with dedicated outdoor watches while offering superior smartwatch intelligence. However, it isn’t without compromises. High-end runners will still lament the absence of native running power metrics, proprietary charging requirements mean your old watch pucks are obsolete, and critical health tools like ECG and blood pressure monitoring remain gated strictly behind the Samsung smartphone ecosystem.
If you already own the original Galaxy Watch Ultra, the upgrade makes sense primarily if you need proper dive tracking, noticeably better battery life, or struggle with direct-sunlight readability. For anyone stepping up from older Galaxy Watches or looking for the absolute best rugged Wear OS experience on the market, the Galaxy Watch Ultra 2 justifies its premium price tag. But I would still wait for some good deals.
