Samsung Galaxy Watch Ultra: The Ultimate Rugged Smartwatch for Adventurers and Athletes

Samsung’s Galaxy Watch Ultra represents a bold entry into the premium rugged smartwatch market, delivering a feature-packed wearable that challenges both Apple’s Watch Ultra and Garmin’s dominance in the outdoor adventure segment. Announced in July 2024, this Android smartwatch features a 1.5-inch display, Exynos W1000 chipset, 590 mAh battery, 64 GB storage, and 2 GB RAM, all housed in a MIL-STD-810H compliant case with sapphire crystal glass.

Design and Durability: Built for Extreme Conditions

The Galaxy Watch Ultra embodies Samsung’s commitment to creating a timepiece that can withstand the harshest environments. The watch has obtained MIL-STD-810H Certification for high and low temperature, altitude, humidity, immersion, salt fog, dust, vibration, and drop resistance. This military-grade testing ensures the device can handle real-world challenges that outdoor enthusiasts regularly face.

Grade 4 titanium is partially applied to the front and back cover areas of the metal frame, excluding the display and physical buttons, while the remaining parts feature a mix of plastic and Grade 2 titanium. This hybrid construction balances durability with wearability, though some users with smaller wrists may find the 47mm case substantial.

The watch’s environmental resistance is equally impressive. Galaxy Watch Ultra withstands temperatures ranging from -20°C to 55°C while being worn on the wrist. Whether you’re scaling frozen peaks or trekking through desert landscapes, this smartwatch is engineered to keep functioning when you need it most.

Display: Brilliance Under Any Conditions

One of the standout features is the exceptionally bright display. The Galaxy Watch Ultra has gained a much more brilliant display at 3,000 nits, ensuring visibility on beaches or mountain tops. This brightness advantage makes a tangible difference when checking metrics during outdoor activities in direct sunlight, addressing a common complaint with earlier Galaxy Watch models.

Enhanced Button Layout and Controls

The watch has gained a new “Quick” button, which can be customized to open a specific app or function and by default opens the Workout menu to select a sport to start. Samsung’s thoughtful placement of this orange Quick button between the button guards of the other two buttons prevents accidental presses, a notable improvement over competing designs.

The top button takes you home from whatever screen you’re on, and the bottom one goes back one screen, while the center Quick Button is configurable but defaults to launching workouts. However, users should note that unlike many other watches, there’s no rotating crown or bezel—navigation relies primarily on buttons and swiping.

Water Resistance and Outdoor Features

The Galaxy Watch Ultra is consistent with 10 ATM water-resistance classification, rated for up to 100 meters of water for up to 10 minutes, and carries an IP68 rating for up to 6 feet of water for up to 30 minutes. While Samsung markets the watch for ocean adventures and water sports, it’s worth noting that the specific ISO certification differs from traditional dive watches.

For hikers and cyclists, the watch includes practical safety features. The Track Back feature must be enabled prior to every hiking or cycling workout session, while the emergency siren emits up to 86-decibel sound and can be heard up to 180 meters away maximum.

Health and Fitness Tracking: Comprehensive Wellness Monitoring

The Galaxy Watch Ultra introduces several groundbreaking health features that set it apart from competitors. For the first time on Galaxy Watch, it offers a Sleep apnea feature that requires at least 2 days of sleep data within a span of 10 days for detection. While this feature is not intended for diagnosis or treatment, it provides valuable insights for users to discuss with healthcare professionals.

The watch introduces the Advanced Glycation End-products (AGEs) index, which for the first time on Galaxy Watch allows users to see how their diet could affect metabolic health. This feature helps users monitor meal choices and maintain peak performance through lifestyle adjustments.

Additional wellness features include the Vascular Load metric, which estimates strain on your circulatory system during sleep by analyzing sleep tracking data, stress levels, and exercise patterns. The Energy Score and other Galaxy AI-powered insights help users understand their overall readiness and recovery status.

The watch can automatically detect and log various workouts including walking, running, swimming, elliptical, and rowing, with a longer list of supported activities than other Wear OS devices. The addition of multisport workout plans makes it particularly appealing for triathletes and cross-training enthusiasts.

Battery Life: Extended Endurance for Long Adventures

In normal battery mode with Always On Display enabled, battery life reaches up to 60 hours, while disabling Always On Display extends it to up to 80 hours. This multi-day battery life represents a significant advantage over many competitors, reducing the need for frequent charging during extended outdoor adventures.

For ultra-endurance activities, the watch offers power-saving modes that can extend battery life even further, though with some feature limitations such as restricted Wi-Fi connection, wake-up gestures, CPU speed, and location services.

Software Experience: Galaxy AI Integration

The Galaxy Watch Ultra runs on Wear OS, customized with Samsung’s One UI Watch interface. One UI makes several significant changes from stock Wear OS, including a more powerful notification system that retains notification bundles from your phone, making it easier to triage long lists of emails or messages.

The watch offers Suggested Replies with Galaxy AI, providing quick text-reply suggestions based on conversation context. Users can control various functions with a double pinch gesture, adding convenient hands-free operation for taking photos, answering calls, or silencing alarms.

One notable quirk: the Galaxy Watch Ultra still defaults to using Bixby as the voice assistant, though users can and should switch to Google Assistant in the settings.

Performance and Storage

Powered by the Exynos W1000 chipset built on a 3nm process, the Galaxy Watch Ultra delivers smooth performance for everyday tasks and workout tracking. The watch comes with 2GB of RAM and generous storage options. The 2024 model includes 32GB of internal storage, while the 2025 refresh doubles this to 64GB, providing ample space for offline music, maps, apps, and workout data.

Ecosystem Integration and Limitations

Some of the Watch Ultra’s features will only work with a Samsung phone, including running ECGs and detecting health issues like sleep apnea and irregular heart rhythms, along with certain Galaxy AI features like the energy score. This ecosystem lock-in may frustrate Android users who prefer other smartphone brands, though the watch remains compatible with any Android device for basic functionality.

The Galaxy Wearable app manages watch connections and settings with a sleek, modern interface that simplifies customization. Meanwhile, the Samsung Health app, though somewhat clunky initially, provides comprehensive tracking and analysis of all your health and fitness data.

Real-World Performance: Accuracy and Reliability

During testing, the watch performed well for normal workouts with automatic laps and reliable instant pace tracking during runs. The inclusion of multiband/dual-frequency GNSS and an improved optical heart rate sensor enhances accuracy for outdoor activities.

However, the watch isn’t without occasional quirks. Some users have reported activities mysteriously stopping or ending during rides, though such incidents appear relatively rare. The multiband GPS generally delivers accurate tracking, though dense tree cover or urban canyons can still impact satellite signal quality.

The 2025 Refresh: Incremental But Valuable Updates

Samsung released an updated Galaxy Watch Ultra in 2025 with modest but meaningful improvements. The 2025 model doubles internal storage to 64GB from the previous 32GB, powered by the same 3nm Exynos W1000 processor with 2GB of RAM and a 590mAh battery.

The Watch Ultra (2025) comes pre-installed with Wear OS 5, layered with Samsung’s updated One UI Watch 8 skin, including the Now Bar feature that shows context-aware controls like timers and media playback on your watch face. Importantly, most of these software features are expected to arrive on the original Galaxy Watch Ultra through updates.

New health features include Vascular Load for estimating circulatory system strain during sleep, Antioxidant Index for skin antioxidant levels, Bedtime Guidance powered by Galaxy AI for personalized sleep scheduling, and a new Running Coach mode with real-time training feedback.

The 2025 version introduces a new Titanium Blue color option alongside the existing Titanium Gray, Silver, and White finishes. The refreshed model costs the same—$649.99—as the original Watch Ultra, making it an even better deal for new buyers.

Who Should Buy the Galaxy Watch Ultra?

The Galaxy Watch Ultra targets a specific audience: active individuals who demand durability, comprehensive health tracking, and multi-day battery life. It excels for outdoor enthusiasts, serious athletes, and anyone who needs a watch that can withstand extreme conditions while providing detailed fitness and wellness insights.

However, the high $650 price tag and chunky 47mm design might make it a tough sell for some users. The Galaxy Watch 7 offers most of the same features at a lower price point with a sleeker design, making it a better choice for casual users or those with smaller wrists.

For Samsung phone owners, the Watch Ultra’s ecosystem integration unlocks its full potential, including advanced health monitoring features like ECG and sleep apnea detection. Android users with other phone brands will still enjoy excellent functionality but may miss out on some premium features.

Final Verdict

The Samsung Galaxy Watch Ultra represents a serious competitor in the premium smartwatch market, offering military-grade durability, exceptional battery life, a brilliant display, and comprehensive health tracking. While it clearly draws inspiration from Apple’s Watch Ultra design language, Samsung has created a capable device that stands on its own merits.

For adventurers, athletes, and anyone seeking a rugged smartwatch that can keep up with an active lifestyle, the Galaxy Watch Ultra delivers impressive performance and features. The 2025 refresh adds valuable storage and software improvements at the same price, making it an even more compelling choice for new buyers. However, existing 2024 model owners can largely skip the upgrade, as most new features will arrive via software updates.

Whether you’re training for a triathlon, hiking mountain trails, or simply want a smartwatch that can handle whatever life throws at it, the Galaxy Watch Ultra proves that Samsung is serious about competing in the premium wearable market.
